Converting renewable biomass and their derivatives into chemicals and fuels has received much attention to reduce the dependence on fossil resources. Photocatalytic ethanol dehydrogenation–acetalization to prepare value‐added 1,1‐diethoxyethane and H 2 was achieved over non‐precious metal CdS/Ni‐MoS 2 catalyst under visible light. The system displays an excellent production rate and high selectivity of 1,1‐diethoxyethane, 52.1 mmol g −1 h −1 and 99.2 %, respectively. In‐situ electron spin resonance, photoluminescence spectroscopy and transient photocurrent responses were conducted to investigate the mechanism. This study provides a promising strategy for a green application of bioethanol.
