Abstract:
The hydrogen evolution reaction is a huge challenge for CO2 electroreduction. Herein, an inside-mode indium oxide/carbon nanotube compound (MWCNTs@In2O3) is developed to maximize the catalytic effect and suppress hydrogen evolution, its HCOOH selectivity can reach up to 92.2% at -16.8 mA cm-2, which is more efficient than In2O3.
