TLDR
In this paper, the authors show that CO2 reduction is always accompanied by a competitive hydrogen evolution reaction as water is used as a hydrogen source, and that intrinsic activity control, geometrical factor, and intrinsic energy control are all involved.Abstract:
Electrochemical CO2 reduction is always accompanied by a competitive hydrogen evolution reaction as water is used as a hydrogen source. In addition to intrinsic activity control, geometrical factor...read more
