Abstract:
Cadmium sulfide (CdS) has been found to be a favorable electrocatalyst for CO2 reduction owing to its appropriate binding energy of the key intermediates that originate from the CdS(002) surface with S vacancy (Sv). In this work, CdS nanorods with a medium Sv content (ca. 9%) give the highest CO Faraday efficiency of 100 ± 0.5% and a partial current density of -20.5 ± 0.2 mA cm-2.
