GBW 2022: Empowering Diversity in Science

16th February 2022, Several locations/Zoom

The NordCO2 consortium is fully committed to promoting diversity in science. Our group has about 30% women, and an unknown number of nationalities (frankly, we never counted!). Very few of our members are originally from the country their work in, less than 5 among our total of 66 people.

We will most likely organise a digital seminar with a physical breakfast at some (hopefully all) of the institutions participating in the consortium, details will be communicated at a later date.

Monthly Seminars

The NordCO2 Monthly Seminars is a series of lectures by experts in the fields relevant to the NordCO2 consortium as well as student talks about their recently published works. The seminars are organised each month by a different institution from the NordCO2 consortium, and the lectures are often accessible to the public. The seminars are held in Zoom, and registration links are in the description of each event.

Lecture by Pr. Marc Robert from the REACTE group at the Laboratoire d’Électrochimie MolĂ©culaire of UniversitĂ© Paris Diderot, France.

Title of the lecture:
“Molecular (photo)electrochemical Reduction of CO2 with Co and Fe Complexes.
Hybrid Catalysis, Highly Reduced Products”

 

Abstract:

Reduction of carbon dioxide has as main objective the production of useful organic compounds and fuels – renewable fuels – in which solar energy would be stored. Molecular catalysts can be employed to reach this goal. They may in particular provide excellent selectivity thanks to easy tuning of the electronic properties at the metal and of the ligand second and third coordination sphere. Recently it has been shown that such molecular catalysts may also be tuned for generating highly reduced products (beyond CO and formate), leading to new exciting advancements.

Hybridization of these catalysts with conductive or semi-conductive materials may lead to enhance stability and new catalytic properties, as well as inclusion of molecular catalysts in devices for applications. This approach bridges between homogeneous and heterogeneous, and it raises new fundamental questions that may further lead to breakthrough in CO2 reduction chemistry.

Our recent results in these various areas will be discussed.

Title of the lecture:
“Theory-Aided Comprehension of CO2 Conversion on Heterogeneous Catalysts”

 

 

 

Abstract:

A transition using sustainable energy sources requires the replacement of fossil-based fuels by
synthetic energy vectors. The conversion of CO2 to generate high-energy-density
(oxy)hydrocarbons catalyzed by heterogeneous catalysts is one of the most attractive routes for
this purpose since such materials are highly active in related CO2/CO conversion reactions.
Theoretical calculations are crucial to understanding heterogeneous catalysts at the atomic
level. This talk will provide an overview of our recent works in the field in thermally promoted
CO2/CO conversions,1-7 highlighting the activity of 2D-Mo2CTx (MXenes)6 and Cu single sites
supported on them (Cu@Mo2CTx).7 Theoretical calculations reveal that Cu@Mo2CTx enables
the simultaneous H2 heterolytic cleavage and C-H bond formation steps. We suggest this is due
to the electronic nature of Cu single sites and the oxyphilic character of the support.7

Title of the lecture:

Metal-organic frameworks for electrocatalytic CO2 reduction

 

 

 

Abstract:

Metal-organic frameworks (MOFs) are materials consisting of metal ions connected via rigid organic ligands. MOFs exhibit permanent porosity and the exposed metal sites render MOFs promising candidates for catalysis. To date, a number of MOFs have been reported to be active for the electrocatalytic CO2 reduction reaction. While MOFs resemble single site catalysts, they show high activity relative to the metal content, but the application of MOFs in electrocatalysis is often limited by their intrinsic poor electronic conductivity. Moreover, MOFs often have lower thermal and chemical stabilities in comparison with e.g. the corresponding metal oxides.
In this talk, approaches to increasing the electrical conductivity will be presented. Moreover, the consequences of the lacking chemical stability on the structure and electrocatalytic performance will be discussed.

Lecture by Professor Julio Lloret-Fillol from the Institute of Chemical Research of Catalonia, Spain.

Title of the lecture:

“Well-Defined Catalysts for Reductive Transformations; From Solar Fuels to Fine Solar Chemicals”

 

 

 

Abstract:

One of the most appealing research areas is the mechanistic understanding of multi-electron multi-proton processes, which is a central part of activating small molecules such as CO2 and H2O.1 Further understanding of how these mechanisms operate is essential for developing effective catalysts for sustainable energy conversion and storage.2

During the presentation, we will mainly focus on well-defined metal complexes as model systems to gain mechanistic information on CO2 and H2O reduction.3-7 We will also disclose factors that could affect the catalytic activity and improve it, such as the effect of the light6 or inhibiting the formation of off-cycle reaction intermediates.7

Title of the lecture:
Fundamental properties of iron–porphyrin (electro)catalysts for O2 reduction, with implications for CO2 reduction

Abstract:
The chemistry of iron-porphyrin complexes with dioxygen has long been studied, inspired by the myriad examples and functions of hemes in metallobiochemistry. Kinetic studies of iron-tetraphenylporphyrin catalysis and electrocatalysis of O2 reduction implicate pre-equilibrium O2 binding and rate-determining protonation of the ferric-superoxide. The steps after that are kinetically invisible but have been probed by examining H2O2/H2O product ratios. Three different mechanisms for the formation of hydrogen peroxide have been identified depending on catalyst structure and reaction conditions. The catalytic turnover frequencies and overpotentials have been shown to follow predictive scaling relationships. These scaling relationships are additive, either by changing multiple aspects of the catalytic system or in the unusual case with the tetra-cationic porphyrin ligand, tetra(oN,N,N-trimethylanilinium)porphyrin. Iron complexes of this ligand are exceptional electrocatalysts for O2 reduction, following work from Costentin, Savéant et al, showing that they are excellent for CO2 reduction. Studies using the four different atropisomers of this catalyst indicate that the cationic charges act primarily by enhancing ancillary anionic ligand binding, more than any specific interactions with a bound O2 or CO2 substrate. The rapid electrocatalysis of CO2 reduction by this catalyst depends on a very high solution concentration of phenol, and the mechanistic implications of the complex electrochemistry will be discussed.

Title of the lecture:
“Electrocatalytic Reduction of CO2 to CO Mediated by Metal Porphyrins: Insights from DFT”

Abstract:
Iron porphyrins are among the most active electrocatalysts for the reduction of CO2 to CO. A more recently reported candidate, zinc bacteriochlorin, has shown comparable activity and improved stability. Why the catalytic activities are similar, despite the central metal atom and the ligand both being different, is still unclear. To gain insight into the activity-determining metal and ligand factors, a density functional theory (DFT) analysis of CO2 reduction using all the four metal–ligand (Fe/Zn–porphyrin/bacteriochlorin) was conducted. This mechanistic comparison highlights metal and ligand properties important for CO2 to CO reduction.

Title of the lecture:
“Optimizing the selectivity of supported nickel catalysts for CO2 catalytic hydrogenation”

Abstract:
The catalytic conversion of CO2 into C2+ hydrocarbons, olefins, or alcohols is considered promising for mitigating CO2 emissions. However, the hydrogenation of CO2 can lead to various C1 products, such as CO via the reverse water–gas shift (RWGS) reaction, CH4 via Sabatier or methanation reaction, CH3OH via selective hydrogenation and, ultimately, C2+ hydrocarbons, olefins, or even oxygenates by combining RWGS with Fischer–Tropsch (FT) reactions. Selectivity remains an issue. The first step, which is the hydrogenation of CO2 through RWGS to form CO and water, is an equilibrium-limited endothermic reaction favored at high temperatures and methane is concomitantly formed over most catalysts as an undesired side product at low temperatures (< 600 °C). Here, we describe a multi-technique in situ and operando approach to characterize and understand how carbon accumulation on Nickel catalysts under CO2 hydrogenation conditions affects selectivity. A classical Ni catalyst was prepared by a simple impregnation-reduction method to obtain 15wt% Ni loading. The catalyst was tested under CO2 hydrogenation conditions (10 °C min-1 from 100 to 800 °C) under 1/4 CO2/H2. The freshly reduced catalyst produced CO (RWGS) and CH4 (methanation reaction) concomitantly at temperatures between 300 and 600 °C. The spent catalyst was used in a successive CO2 hydrogenation reaction cycle, but the production of CH4 was suppressed, and CO was the main product at all temperatures. We understand that the suppression of CH4 formation is an essential step towards an improved selectivity. Here we investigated Ni catalytic sites’ changes under reaction conditions and simulated atmospheres to find correlations with the reaction selectivity. Spectroscopic studies by CO-DRIFTS and XPS in different life stages were used to shed light on the surface structure change upon sequential reaction cycles and provided valuable information about the role of carbon on the Ni surface and on the reaction pathways. EXAFS was also evaluated under operando conditions during two successive cycles of CO2 hydrogenation reactions, suggesting that a Ni3C-like phase accumulates on the catalyst, which may be responsible for preventing the formation of CH4. First-principle simulations were performed to describe CO adsorption’s strength at the catalyst surface and gain insights into the underlying mechanism. Overall, the adsorption strength of CO is greatly diminished with the deposition of C on the surface of metallic Ni particles, which ultimately results in the almost complete elimination of the CO methanation reaction. The extensive spectroscopic (XAS, XPS, DRIFTS) and morphologic (XRD, TEM) evaluation of the Ni catalyst present clear evidence of the role of surface Ni carbide species formed in-situ at high temperatures in suppressing CH4 formation during CO2 hydrogenation.
