Summary: The construction of an ultrathin 2D ZnIn2S4/g-C3N4 Z-scheme heterojunction through in-situ growth of ZnIn2S4 on g-C3N4 allows for greatly improved hydrogen evolution performance by carefully regulating the interface structure. The optimized photocatalyst demonstrates significant photocatalytic activity without Pt, attributing to the synergistic effect of abundant active sites, enhanced photoresponse, and valid interfacial charge transfer channels. Spectroscopic analyses and density functional theory (DFT) calculations confirm that the enhanced photocatalytic performance is also due to promoted interfacial charge separation in the 2D Z-scheme heterojunction.

Summary: This study investigates the issue of voltage plateau regulation for cathode materials with fixed active center in sodium-ion batteries. A high-entropy substitution strategy is utilized to alter the crystal structure of the cathode materials, resulting in enhanced electronic conductivity and reduced diffusion barrier for Na+. The carbon-free high-entropy Na3V1.9(Ca,Mg,Al,Cr,Mn)(0.1)(PO4)(2)F-3 cathode exhibits higher mean voltage and advantageous energy density. The introduction of high entropy enables higher working voltage of the cathode, and coupling with a hard carbon anode achieves high specific energy density.

Summary: Alloying with Sn is an effective strategy to inhibit hydrogen evolution and dendrite growth of Zn metal anodes in rechargeable aqueous batteries. In-situ monitoring shows that Sn alloy electrodes have significantly lower hydrogen evolution compared to pure Zn electrodes, while also providing favorable Zn nucleation sites for more uniform Zn deposition. The Zn-Sn alloy electrodes demonstrate improved cycling performance in terms of plating/stripping cycles and depth of discharge, making them a practical solution for stabilizing Zn metal electrodes in rechargeable aqueous batteries.
