Summary: In this study, carbon nitride hollow spheres with adjustable sizes were successfully fabricated using a template-free supramolecular pre-assembly strategy. The sizes of the hollow spheres could be manipulated by changing the pre-assembly temperature. The optimal sample showed excellent photocatalytic hydrogen evolution rate in the visible-light region, which was significantly higher compared to traditional materials. This improvement can be attributed to the unique structure of the material and its remarkable light absorption ability, electrical conductivity, and charge separation capability.

Summary: In this study, a new synthetic strategy was developed to design carbon nanoparticles encapsulated cobalt-based heterogeneous materials for efficient catalysis of peroxymonosulfate in the degradation of harmful substances. It was found that the addition of cobalt increased the surface defects of carbon materials, leading to enhanced catalytic activity. Cobalt nanoparticles served as the main active sites, while the defects and carbonyl groups on carbon materials also contributed to the catalytic reaction. The results of this study are of significant importance for the application of metal organic framework-derived carbon-supported metal catalysts in wastewater purification.

Summary: In this study, a BN/MXene/ZnIn2S4 S-scheme photocatalytic heterojunction was constructed by growing the etched BN/MXene on the ZnIn2S4 nanosheets directly. The introduced electron trapping effect of MXene successfully avoided the photocatalytic inferiority caused by BN's broader band gap and poor conductivity. With the excellent hydrogen production performance and degradation efficiency, this work provides a feasible strategy for constructing an S-scheme heterojunction for energy and environmental remediation.

Summary: Ternary heterojunction photocatalysts show improved reduction and oxidation properties for environmental and energy applications due to enhanced transport and separation of photogenerated electrons and holes. In this study, Ti3C2@TiO2/g-C3N4 photocatalyst with optimized carrier transport and separation was successfully synthesized using electrostatic self-assembly. The ternary heterostructured photocatalyst exhibited higher photocatalytic degradation performance for removing rhodamine B and 4-chlorophenol. The synergistic effect of heterojunction and Schottky barrier suppressed the recombination of the photogenerated electron-hole pairs, while the Ti3C2 served as an active site for adsorption and activation of organic pollutants.

Summary: Bimetallic sulfides composed of highly dispersed Cu-doped ZnS composites were proposed as catalysts for photocatalytic H2 evolution. These catalysts exhibited an optimal H2 evolution activity of over 1569 μmol/g at pH = 3 and 2 hours of visible light irradiation, without the consumption of sacrificial agents or cocatalysts. The introduction of Cu into the ZnS lattice resulted in a narrower energy bandgap and a nonequilibrium charge distribution, which enhanced the absorption of visible light and facilitated the separation and migration of photoinduced carriers.
