Synergistic Ru single atoms and S vacancies on CdS nanosheets for efficient ethanol photoreforming

Caption

Schematic illustration of the ethanol photoreforming process over Ru0.2-CdS. Under light irradiation, Ru single atoms (Ru SAs) trap photogenerated electrons while sulfur vacancies (S vacancies) capture holes, synergistically promoting charge separation. Ethanol is selectively converted into hydrogen (H2) and 1,1-diethoxyethane (DEE) with 100% selectivity. The dual-functional site design enables an 81.5-fold enhancement in H2 evolution compared to pristine CdS.
