外文摘要：Molybdenum-based metal oxide catalysts are attracting widespread attention in the field of photocatalysis due to their significant applications in addressing energy and environmental challenges.As a new three-dimensional molybdenum-based metal oxide photocatalyst,NaZn2(OH)(MoO4)2·H2O is highly promising as a semiconductor catalyst for enhancing photocatalytic performance,thanks to its ease of preparation and environmental friendliness.Herein,we prepared an S-scheme heterojunction photocatalyst composed of NaZn2(OH)(MoO4)2·H2O and CdS,which enabled efficient H2 production through photocatalysis,ad-dressing issues associated with the rapid recombination rate of photogenerated carriers.The hydrogen generation yield of NZM/CdS-30 reached 5335 μmol g-1 h-1,approximately 30 and 953 times higher than those of CdS and NaZn2(OH)(MoO4)2·H2O,respectively.Moreover,we verified the mechanism through in-situ XPS analysis to elucidate the activity enhancement.Our research provides an innovative universal and effective synthetic strategy of design S-scheme heterojunction for hydrogen production from solar water splitting.
