Summary: The study found that in NaOH solution, the hole scavenging capability of Cd0.5Zn0.5S is enhanced, which effectively reduces the photocorrosion of the catalyst and increases the reaction rate of water splitting. Furthermore, under high pH conditions, the water oxidation pathway shifts to direct OH- oxidation, promoting the splitting of water.

Summary: Photocatalytic hydrogen evolution is a promising solution to energy and environmental crises. This work developed P-dots-COOH/WS2 and P-dots-SH/WS2 heterostructure composites by mixing COOH and SH functional group polymer dots with WS2 nanosheets. The P-dots-SH/WS2 composite exhibited significantly enhanced photocurrent density and reduced charge transfer resistance, which may be attributed to the coordination between the thiol functional group and the WS2 nanosheets.

Summary: Modulation of electronic structure via heterointerface engineering is an appealing strategy to promote the hydrogen evolution reaction (HER) performance of a pH-universal electrocatalyst. In this study, a CoS2-MoS2 heterostructure with plentiful heterogeneous nanointerfaces is synthesized and exhibits superb catalytic activity and long-durability towards HER in both acidic and alkaline solutions. The synergistic modulation of electronic and geometric structures accounts for the excellent performance of CoS2-MoS2. This work provides an exciting avenue for fabricating efficient wide-pH electrocatalysts through an interface-induced strategy.
