Abstract:
The conversion of CO2 into carbon-based fuels and chemicals via the electrocatalytic CO2 reduction reaction (CO2RR) offers an attractive route to reducing the CO2 emission for carbon neutrality. Currently, high-purity CO2 gas has been widely used as the feedstock for most of the CO2RR studies, while CO2 sources with a typically low concentration impose the extra cost for CO2 capture and purification steps. The direct utilization of low-concentration CO2 for the CO2RR is a promising approach to substantially address this problem. In this Perspective, we first highlight the prominent advantages of direct electroreduction of low-concentration CO2. Then we focus on the summary of several important design strategies for CO2RR in diluted CO2 and gas impurities-containing CO2 atmosphere. Finally, we propose personal outlooks on future challenges and some opportunities for this fascinating research field.

Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
