Summary: 2D BiOCl porous nanosheets (BOC-PNS), prepared by triblock polymer (F127) assisted mechanical ball milling, possess a (001) main exposed plane and a porous structure increasing the edge (110) facet. The (001)/(110) heterojunction enhances directional migration and separation of photogenerated carriers. Under simulated sunlight, the CO yield of BOC-PNS is significantly enhanced by the rich edge confinement effect, reaching 28.2 μmol g-1 h-1, which is 2.1 and 2.8 times that of BOC nanosheets (13.5 μmol g-1 h-1) and nanoplates (9.9 μmol g-1 h-1), respectively.

Summary: In this study, we designed novel ultrathin porous Bi2WO6 nanosheets with rich surface oxygen vacancies. The oxygen vacancies can narrow the bandgap, enhance light absorption, and promote electron separation and transfer. Additionally, the multiplication of oxygen vacancies increases the adsorption energy of O-2, activating O-2 to produce more center dot O-2(-). The porous structure enhances the adsorption capacity of the nanosheets to tetracycline molecules, allowing for a more efficient use of the center dot O-2(-). The nanosheets exhibit a degradation efficiency approximately 52.6 times higher than bulk Bi2WO6, showing great potential for removing organic pollutants.

Summary: The continuous presence of organic pollutants in industrial wastewater poses a significant threat to human health, necessitating urgent and effective treatment. Photocatalytic degradation technology, specifically the use of TiO2 photocatalysts, provides a viable solution for the removal of organic pollutants. However, the limited absorption of visible light by TiO2 hinders its full utilization. To address this issue, the study developed an environmentally friendly synthesis of Ag-coated on micro-wrinkled TiO2-based catalysts, enabling extended absorption of visible light. The synthesized C/F-Ag-TiO2 composite exhibited a significantly lower band gap energy and achieved a remarkable degradation rate under visible light, making it a promising candidate for highly efficient environmental remediation.

Summary: In this study, skin B/N-doped red anatase TiO2 {001} nanoflakes were synthesized to overcome the limited visible light response of photocatalysts. The introduction of boron dopants and nitrogen atoms on the surface of TiO2 nanoflakes effectively shortens the charge transport path, leading to efficient visible light responsive photocatalytic activity.

Summary: In this study, a photocatalyst constructed with a small amount of amorphous BiOCl nanosheets assembled on TiO2 showed excellent performance in toluene oxidation to benzaldehyde. The selectivity reached 85% at 10% conversion, and the benzaldehyde formation rate was significantly higher than that of bare TiO2 and BOC. The microstructure based on heterojunctions and the presence of surface oxygen vacancies in the amorphous BiOCl were found to be crucial for the high selectivity and performance.

Summary: Ta3N5/CdS core-shell S-scheme heterojunction nanofibers were prepared by growing CdS nanodots on Ta3N5 nanofibers via a wet-chemical method. These nanofibers exhibit excellent photocatalytic degradation and mineralization performance for tetracycline, as well as efficient photocatalytic reduction performance for Cr(VI). The formation of a favorable core-shell fiber-shaped S-scheme heterostructure with tightly contacted interface and maximum interface contact area ensures effective photo-carrier disintegration and optimal photo-redox capacity, leading to superior photo-redox ability. Furthermore, critical environmental factors and the degradation products of tetracycline were evaluated, and the decrease in eco-toxicity of TC intermediates was confirmed.

Summary: This study develops a multidimensional In2O3/In2S3 (IO/IS) heterojunction with abundant lattice distortion structure and high concentration of oxygen defects to improve the performance of photocatalytic CO2 reduction. The heterojunction with close contact interfaces facilitates electron transmission and enhances the adsorption and activation of CO2 on the catalyst surface. The perfect combination of band matching oxide and sulfide effectively reduces the energy barrier of the CO2 reduction reaction. Furthermore, the lattice distortion structure provides additional active sites and optimizes the reaction kinetics. The optimal IO/IS heterojunction demonstrates superior CO2 reduction performance. This work emphasizes the importance of tight interfaces in heterojunction for improving CO2 photoreduction performance and provides an effective strategy for constructing heterojunction photocatalysts.
