Synergistic Coupling of Interfacial Oxidation Sites and S-Scheme Heterojunction in CuWS@SnInS Core-Shell Nanocomposites Boosting CO Photoreduction Efficiency.

Photocatalytic CO reduction offers a dual solution to mitigate the energy crisis and reduce carbon emissions. In situ synthesis of the CuWS@SnInS (CWS@SIS) composite has established S-S bonds at the interface, which act as atomic-scale interfacial "bridges" to stabilize the heterojunction interface. SnInS nanosheets are uniformly dispersed on the CuWS surface, activating the (101) crystal plane of CuWS to consume photogenerated holes.

Enhanced hydrophobicity of the current collector modifier for Zn anode endows improved longevity.

Though zinc-ion batteries have gained intensive attention recently, their application prospects have long been hampered by Zn dendrite evolution and water-involved side reactions, especially for thin and highly utilized Zn anodes. Coating a modified layer on the current collector is a common strategy to improve the reversibility of Zn plating/stripping. Hydrophilic modifier with high zincophilicity, usually affords uniform Zn deposition but exhibits intrinsic limitations in repelling water molecules, while hydrophobic modifiers shows excellent water-resistance.
