Abstract:
A twin Cu0.3Zn0.7S solid solution is developed for carbon dioxide photocatalytic reduction, in which ordered stacking faults induce homojunctions to enhance the separation and migration of photogenerated charge carriers. The high-coverage of the *CO intermediate is responsible for promoting C-C coupling. The developed photocatalyst exhibits efficient CO2-to-C2H4 conversion with a C2H4 production rate of 8.45 μmol g-1 h-1 and an electron selectivity of 53.6%.
