研究目的
To further enhance the photocatalytic performance of BiOCl by synthesizing a reduced graphene oxide-modified ternary compound photocatalyst and studying its photocatalytic performance and carrier migration.
研究成果
The introduction of rGO significantly enhances the photocatalytic efficiency of NYF-Bi by promoting the separation of photoelectron-hole pairs and increasing the specific surface area, leading to improved pollutant adsorption and degradation under visible light.
研究不足
The study focuses on the photocatalytic performance under visible light and does not extensively explore the effects under other light conditions or the scalability of the synthesis method.
1：Experimental Design and Method Selection:
A facile hydrothermal reduction reaction was used to synthesize the reduced graphene oxide-modified ternary compound photocatalyst.
2：Sample Selection and Data Sources:
The samples included BiOCl, NYF, NYF-Bi, and NYF-Bi-rGO, with RhB used as the target pollutant for photocatalytic activity evaluation.
3：List of Experimental Equipment and Materials:
Included a 500-W xenon arc lamp with an optical filter, U-3010 ultraviolet–visible spectrophotometer, D/Max-2500pc diffractometer, JSM-7800F field emission SEM, Tecnai G20 microscope, and others.
4：Experimental Procedures and Operational Workflow:
The photocatalytic activity was evaluated under the irradiation of a 500-W xenon arc lamp with an optical filter (λ > 700 nm).
5：Data Analysis Methods:
The absorbance values of the degraded RhB solutions were measured using a UV–Vis spectrophotometer.
