研究目的
Investigating the synthesis and photocatalytic performance of nanosheet-assembled Bi2WO6 microspheres under visible light irradiation for the degradation of organic pollutants.
研究成果
The nanosheet-assembled Bi2WO6 microspheres demonstrated excellent photocatalytic activities under visible light irradiation, with a photodegradation efficiency of about 98% for RhB in 50 min, suggesting good prospects for water treatment applications.
研究不足
The study focuses on the synthesis and photocatalytic performance under specific conditions; variations in environmental factors and scalability for industrial applications were not explored.
1：Experimental Design and Method Selection:
A facile hydrothermal strategy was employed to synthesize nanosheet-assembled Bi2WO6 microspheres using CTAB and PVP as surfactants under mild conditions.
2：Sample Selection and Data Sources:
Bismuth nitrate pentahydrate and sodium tungstate dihydrate were used as precursors.
3：List of Experimental Equipment and Materials:
XRD, SEM, TEM, HRTEM, XPS, UV–vis spectrometer were used for characterization.
4：Experimental Procedures and Operational Workflow:
The synthesis involved hydrothermal treatment at 120 °C for 24 h, followed by washing and drying.
5：Data Analysis Methods:
The photocatalytic activity was evaluated by degrading RhB under visible light irradiation, with UV–vis absorption spectra used to measure concentration variation.
