Abstract

Abstract : The selectivity control between hydrogen evolution and CO2 reduction at the interface of a semiconductor/electrolyte junction is described by O. S. Joo et al. in their Communication on page 16395 ff. Competition between CO2 reduction and hydrogen evolution was observed on (photo)electrodes under electrochemical conditions. However, hydrogen evolution was suppressed under photoelectrochemical conditions, showing a high selectivity for CO2 reduction using an identical electrode/electrolyte system.
