Electrolyte Driven Highly Selective CO₂ Electroreduction at Low Overpotentials

Electrochemical CO2 reduction reaction (CO2RR) is a promising technology to use renewable electricity to convert CO2 into value-added carbon-based products. The low-cost, active, selective, and stable catalysts will play a key role in achieving industrialized CO2RR. The electrolyte assists a catalyst in achieving all its latent capability. Here the concentration effect of KHCO3 in CO2RR was systematically investigated on the low-cost core–shell...
