Title:
Highly selective electroreduction of CO2/CO to C2+ alcohols |
Abstract:
The increasing global energy demand and gradually short fossil fuels with the fast advancement of industrialization require to develop sustainable and green fuels. Carbon one (C1) molecules (including CO, CO2, CH4, CH3OH and HCHO) are important carbon resources that are usually abundant in nature or obtained from non-petroleum carbon resources easily, which plays a key role in the chemical and energy industry. The selective conversion of cheap carbon feedstock C1 molecules into C2+ alcohol liquid products is an attractive route due to their high added value, high energy density and convenient storage.
Electrocatalytic CO2/CO reduction technique driven by electrical energy provides a mild and environmentally pathway to high selective synthesis C2+ products. Though some good progresses have been made in the electrocatalytic reduction of CO2/CO to C2+ alcohols, but at the same time, there also exists some problems such as low selectivity and poor stability. Therefore, in order to achieve the further development of the electrocatalytic reduction of C1 molecules to C2+ alcohols, it is necessary to carry out comprehensive consideration from the design of catalyst, reaction conditions, electrolytic device. In this talk, I would like to share the recent progress related to new catalysts and routes for highly selective electroreduction of CO2/CO to C2+ alcohols.
