Exploiting large-size monolithic semiconductor photocatalyst sheet/layer with superior photocatalytic hydrogen production performances is challenging but important. This study constructed an amorphous MoSx -CdS monolithic heterostructured photocatalyst sheet through a one-step potentiostatic electrodeposition process. The photocatalyst demonstrated an optimized H-2 generation rate of 4476 mu mol h(-1) g(-1) and excellent operability during photocatalytic H-2 generation and recycling processes, making it promising for practical applications in photocatalysis, photoelectrocatalysis and beyond.
Exploiting large-size monolithic semiconductor photocatalyst sheet/layer with superior photocatalytic hydrogen production performances through facile and scalable methods is an important research direction in promoting the practical application of traditional particulate semiconductor photocatalyst, yet challenging. Here we constructed an amorphous MoSx -CdS monolithic heterostructured photocatalyst sheet (a-MoSx -CdS/Ti) with maximal size of similar to 100 cm(2) through a one-step potentiostatic electrodeposition process of 5 min on titanium mesh used as photocatalyst support. Owing to synergic effects of favorable light absorption, abundant active sites for proton reduction, effective photogenerated charge separation and robust structural integrity, the a-MoSx-CdS/Ti not only exhibits an optimized H-2 generation rate of 4476 mu mol h(-1) g(-1), but also demonstrates excellent operability during photocatalytic H-2 generation and subsequent recycling processes, greatly improving its applicability. This work presents a straightforward and practical route to produce efficient, robust and easily operable photocatalytic H-2 production system which expectantly finds promising practical applications in photocatalysis, photoelectrocatalysis and beyond.
