Summary: The combination of SnS2 coupling was used to modify SnO2 nanoparticles, constructing a SnS2/SnO2 heterostructure. The composites exhibited enhanced photocatalytic activity and an extended light absorption range to the visible region, leading to efficient removal of environmental pollutants. Superior photocatalytic performance was attributed to the effective separation of photoinduced carriers and enhanced light absorption.

Summary: A flower-like ZnO/SnS2 heterojunction was constructed as a photocatalyst, which showed improved efficiency in the degradation of organic dye and hydrogen evolution. This enhancement was attributed to the special hierarchical structure and synergetic effect of the ZnO/SnS2 heterojunction, which increased the specific surface area and promoted the separation of photogenerated electron-hole pairs.

Summary: Semiconductor photocatalysis is effective for solving energy demand and environmental pollution issues. ZnIn2S4-based photocatalysts have attracted attention due to their suitable energy band structure and good visible light responsiveness. In this study, ZnIn2S4 catalysts were modified by metal ion doping, heterojunction construction, and co-catalyst loading. The resulting composite photocatalyst exhibited enhanced absorption and hydrogen production efficiency. The addition of MoP as a co-catalyst further improved the hydrogen production performance and cycle stability of the catalyst.

Summary: This paper investigates the catalytic effect of piezoelectric materials on photocatalysis and prepares a flower-like Bi4Ti3O12/BiOCl (BTO/BOC) composite catalyst. The efficiency of photogenerated carrier separation is evaluated through electrochemical, PL, and ESR tests. The built-in electric field of BOC helps facilitate the separation of photogenerated carriers, reducing recombination rates and improving photocatalytic efficiency. The combination of piezoelectric effect and photocatalysis achieves high-efficiency co-catalysis of BTO/BOC piezoelectric photocatalyst.

Summary: Researchers developed a flower-like Co-Mo2C sphere/g-C3N4 heterostructure photocatalyst derived from biochar for the degradation of pharmaceuticals and personal care products (PPCPs). The sharp-edged open-up nanoflake structure allowed for fast charge collection and separation. DFT calculations and experimental characterizations revealed the enhanced intrinsic photocatalytic activity of the catalysts, particularly the role of Co atoms. The Co-Mo2C nanoflower catalyst displayed superior photocatalytic activity compared to the Mo2C/g-C3N4 bulk due to its multifaceted open-up surfaces, higher electron density, more efficient charge transfer ability, and prolonged lifetime of photogenerated charge carriers.

Summary: A series of beta-Bi2O3 materials with different Co doping amounts were prepared via a co-precipitation and pyrolysis process. Co doping enhanced the visible light utilization rate by reducing the band gap and improving electron-hole separation efficiency, leading to optimal efficiency for both electron-hole separation and antibacterial effect when doped with 0.4% Co. The enhanced antibacterial properties of 0.4%-CBO were attributed to increased production of reactive oxygen species (ROS), particularly center dot O-2(-), which contributed significantly to its antibacterial effect.

Summary: In this study, flower-like pure SnS2 and alkali metals doped-SnS2 nanostructures were successfully synthesized by a simple single-step solvothermal method. The presence of dopants in SnS2 led to increased interlayer distance and dislocation intensity, resulting in better electrochemical performance. Among the alkali metals, Na doping showed the highest current density and capacitance performance, attributed to its higher conductivity and expanded interlayer spacing.
