Summary: Designing nanostructured photoelectrodes with unique morphology and suitable band structure is essential for potential photoelectrochemical applications. In this study, compact Sn3O4 nanoflakes with a smooth surface were grown directly on a carbon paper substrate using a simple hydrothermal method. The molar ratio of Sn2+ and Sn4+ ions in the Sn3O4 nanoflakes was modulated through subsequent H2O2-assisted hydrothermal treatment. The effect of different molar ratios on the energy band and the evolution of the surface morphology of the nanoflakes were systematically investigated. By utilizing the H2O2-assisted hydrothermal process, a highly efficient photoelectrode based on Sn3O4 nanoflakes was prepared, exhibiting a larger active surface area and suitable band structure, leading to excellent photocurrent response and photocatalytic performance for H2 production.

Summary: A novel hierarchical Au/black phosphorus nanosheets/ZnIn2S4 (Au/BPNSs/ZIS) heterojunction photocatalyst was synthesized by growing ZnIn2S4 (ZIS) nanosheets on black phosphorus nanosheets (BPNSs) and depositing Au nanoparticles on the ZIS surface. The optimized Au/BPNSs/ZIS exhibited a significantly higher hydrogen evolution rate than pure ZIS and few-layer BPNSs. The improved photocatalytic performance of BPNSs/ZIS was attributed to the formation of Zn-P bonds and the interface electric field that facilitated interface charge transfer, while the deposition of Au nanoparticles formed Schottky junctions and further enhanced the photocatalytic activity. This work provides a new approach for developing BP-based heterojunctions in photocatalysis.

Summary: Infinite coordination-polymer particles (CPPs) show promise for solar energy conversion. However, the range of organic ligands and modification strategies for CPPs are limited, hindering their applications. This paper describes a competitive evolution process that transforms Zn-based crystallites into amorphous particles. By controlling organic linkers, six Zn-CPPs with multivariate characters were selectively derived. These CPPs were then self-pyrolyzed to form hollow zinc oxide particles and effectively modified with ultrathin doped nanosheets. The resulting double-sided heterojunctions exhibit excellent solar H-2-releasing activity and stable cyclability.

Summary: A hierarchical Co3S4/CeO2 nanorod array on cobalt foam (Co3S4/CeO2-CF) was successfully fabricated via a one-step hydrothermal method. The CeO2 nanorod was fully covered by Co3S4 nanosheets, creating a hierarchical core-shell nanostructure. The Co3S4/CeO2 nanostructure, formed through doping of CeO2 and Co3S4 during the hydrothermal process, exhibits reduced free energy barrier in OER process. The Co3S4/CeO2-CF catalyst shows excellent catalytic activity for overall water splitting and remarkable stability, promising potential for bifunctional electrocatalysis.

Summary: Hierarchical direct Z-scheme composites of ultrathin ZnIn2S4 nanosheets on HxMoO3 nanobelts exhibit significantly higher H-2-production activity than pristine ZnIn2S4. The high conductivity and tunable charge transfer efficiency of the HxMoO3 component contribute to the effective transport of charge carriers.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
