Abstract

Front cover image: Identification of the reaction sites though atomic-level perspective is significant for designing highly efficient CO2 reduction photocatalysts. In article number 10.1002/cey2.264, Wang and co-workers report a desirable atomic-level sulfidation strategy over an Aurivillius-related photocatalyst Bi2O2SiO3, which facilitate the local charge separation, contributing to enhanced CO2 reduction rate and selectivity. The system also displays feasibility in diluted CO2 conditions, typically hindered by the deficient reactive sites in conventional systems.
