Electrocatalytic CO2 reduction to C2+ products through hydrogen-assisted C-C coupling |
| 초록 |
Electrocatalytic reduction of CO2 into fuels and chemicals is promising route for CO2 utilization. Copper catalysts have been reported that they have properties to produce valuable hydrocarbon (C2+ product; ethylene) and alcohols. The formation of *CHO intermediates for C2+ formation is the key factor to achieve high activity and selectivity for multielectronic CO2 reduction. Better control for C2+ production may be possible via the C-C bond construction between the intermediates, thus the coupling process should be promoted on reaction mechanisms. We will suggest some strategies to boost the water dissociation on the copper electrode surface with various metal oxide cocatalysts, which can enhace water activation, CO adsorption and hydrogenation of adsorbed *CO to *CHO intermediate that can readily undergo coupling. |
