Structure-function Relationships in CO2 Electrocatalysis (CO2cat)
Time & Location
About the Event
Electrocatalytic conversion of CO2 into hydrocarbon fuels and chemical feedstocks is considered as a viable way to assist the energy transition away from fossil fuels. Currently, various groups around the world focus on optimizing the catalytic materials through variations in size, shape and composition, which has already resulted in improved catalyst stability and CO2 conversion efficiencies up to 80% for base chemicals such as carbon monoxide and ethylene. However, only several examples have successfully shown that longer hydrocarbon chains can be formed through CO2 electroreduction, albeit with moderate efficiency. In order to understand the limiting factors and take the next step towards the efficient production of longer hydrocarbon chains, the attention of several researchers has moved towards in situ/operando spectroscopy and modelling. Through in situ/operando spectroscopy and modelling, the factors that govern C-C coupling toward long chain hydrocarbons can potentially be elucidated, which can be used to design improved catalyst materials in terms of catalytic activity, stability and selectivity.
‘Structure-function relationships in CO2 electrocatalysis’ is an online seminar in which we want to focus on the efforts in material design, in situ/operando spectroscopy and modelling to couple the structure of the electrocatalyst to its catalytic performance. The overarching aim is to build bridges between these efforts and move toward combinations that will result in a full understanding of the catalyst at work: from the nanoscale active sites to the bound intermediates to the production of value-added compounds.
