研究目的
Investigating the photocatalytic performance of CeO2/black phosphorus heterostructure nanocomposite in the degradation of bisphenol A (BPA) under visible light.
研究成果
The CeO2/BP composite significantly enhances the photocatalytic degradation of BPA under visible light due to the formation of an indirect Z-scheme heterojunction intermediated by oxygen vacancies, which improves charge separation and preserves high redox potential.
研究不足
The study focuses on the photocatalytic degradation of BPA under specific conditions and does not explore the stability of the CeO2/BP nanocomposite over extended periods or under varying environmental conditions.
1：Experimental Design and Method Selection:
A two-step hydrothermal and deposition method was used to synthesize CeO2/BP nanocomposites.
2：Sample Selection and Data Sources:
BP was purchased from Nanjing Xianfeng Nano Material Technology Co., Ltd. Other chemicals were of analytical grade.
3：List of Experimental Equipment and Materials:
XRD, TEM, UV–Vis, FT-IR, XPS, and a photocatalytic reactor with a 300 W xenon lamp were used.
4：Experimental Procedures and Operational Workflow:
The synthesis involved ultrasonic exfoliation of BP, mixing with Ce(NO3)3·6H2O and HMT, calcination, and then combining with BP in NMP. Photocatalytic degradation of BPA was monitored under visible light.
5：Data Analysis Methods:
The degradation rate was calculated based on absorbance measurements.
