On the Role of Sulfur for the Selective Electrochemical Reduction of CO2 to Formate on CuSx Catalysts

The efficient electroreduction of CO2 has received significant attention as it is one of the crucial means to develop a closed-loop anthropogenic carbon cycle. Here, we describe the mechanistic workings of an electrochemically deposited CuSx catalyst that can reduce CO2 to formate with a Faradaic ef... View More
