Summary: Hierarchical Bi2WO6 nanostructures with planar arranged nanosheets showed higher photocatalytic nitrogen fixation rate compared to dispersed nanosheets, attributed to chemisorption on the hierarchical structures and enhanced surface oxygen vacancies. The effect of EG dosage on the growth mechanism and behavior of the nanostructures was tested, indicating a potential strategy for improving photocatalytic performance.

Summary: A novel S-scheme heterojunction of In2S3/Bi2WO6 hybrid catalyst was synthesized by assembling In2S3 nanoparticles on Bi2WO6 microsphere through a simple precipitation route. The resulting materials were characterized for their morphology, structures, composition, chemical and optical properties. The In2S3/Bi2WO6 composites exhibited superior photocatalytic behavior for dyes decomposition and showed good stability and reusability. The improved photoactivity was attributed to the formation of S scheme heterojunction, which facilitated photocarriers disassociation and maintained strong redox power. The decomposition pathway of Rhodamine B was revealed and the S-scheme charge transfer mechanism was elucidated.

Summary: In this study, a hierarchical ZnO microsphere precursor was prepared using a hydrothermal method, and a controllable morphology ZnO catalyst was produced through annealing at different temperatures. The catalyst annealed at 400 degrees C showed the best photocatalytic activity for the degradation of dye molecules, and its structure was confirmed to be a 2D cellular network composed of two-dimensional nanosheets through electron microscopy measurements.

Summary: This study combines piezocatalysis and photocatalysis to achieve efficient piezo-photocatalytic activity. The optimized 1T/2H MS/BWO piezo-photocatalyst shows excellent degradation efficiency of diclofenac under the combined action of sunlight and ultrasound. The 1T/2H MS/BWO composite generates a strong polarization electric field to accelerate carrier separation and improve the piezo-photocatalytic activity. The 1T/2H MoSe2 also exhibits superior properties compared to 2H MoSe2.

Summary: Flower-like Bi2WO6/BiOCOOH heterojunction photocatalysts were successfully synthesized by one-pot method. They exhibited enhanced visible light absorption and improved photocatalytic activity due to the efficient separation of photogenerated electron and hole pairs. The degradation experiments of tetracycline and ciprofloxacin under simulated sunlight irradiation demonstrated their excellent performance.

Summary: Visible-responsive photocatalysts for environmental purification and fuel generation are highly sought after. In this study, hierarchical BWO microballs modified with noble metals were prepared and their properties were investigated. Results showed that hierarchical morphology had a negative impact on photocatalytic activity, but accelerated the degradation of model dye and hydrogen generation under specific conditions. The type and properties of noble metal also influenced the overall performance.

Summary: In this work, Cu2FeSnS4 (CFTS) microspheres were prepared via solvothermal method and their photocatalytic performance towards the degradation of organic pollutants was studied. The 3D hierarchical CFTS microspheres prepared at 180 degrees C showed improved photodegradation performance compared to samples prepared at lower temperatures, attributed to their large surface area, mesoporous structure, and enhanced charge separation and transfer. The use of octadecyl amine and L-cystine during the solvothermal process contributed to the successful synthesis of these microspheres.

Summary: A series of direct Z-scheme FeIn2S4/Bi2WO6 hierarchical heterostructures were synthesized and showed enhanced photocatalytic activity for TCH degradation. The optimal component ratio of FeIn2S4 to Bi2WO6 was determined to be 10 wt% for the highest degradation activity. Efficient separation of photogenerated holes and electrons based on the construction of direct Z-scheme system contributed to the enhanced photocatalytic activity.

Summary: In this study, hierarchical and hollow microspheres assembly of one-dimensional zinc-trimesic acid (Zn-BTC) MOF nanospikes were successfully synthesized using a single step solvothermal synthesis method. The formed Zn-BTC hierarchical and hollow microspheres were annealed to form ZnO/C hierarchical nanocomposite microspheres. These hierarchical nanocomposite microspheres exhibited enhanced photocatalytic activities for water remediation. The improved photocatalytic performance was attributed to the synergistic effect between the carbon matrix and well-dispersed ZnO quantum dots.
