Visible-Light Induced Effective Photoreduction of CO2 to CO Catalyzed by Colloidal CdS Microcrystallites

Abstract

Abstract Colloidal CdS microcrystallites prepared from Cd(ClO4)2 and H2S in N,N-dimethylformamide catalyze effective and selective photoreduction of CO2 to CO with apparent quantum yield, Φ1/2CO = 0.098 (400 nm) using triethylamine as a sacrificial electron donor.
