研究目的
To fabricate In2S3/UiO-66 hybrids with enhanced photocatalytic activity towards methyl orange and tetracycline hydrochloride degradation under visible-light irradiation.
研究成果
The In2S3/UiO-66 hybrids, especially ISU-40%, exhibit superior photocatalytic performance under visible light compared to pure In2S3 and UiO-66, attributed to strong visible light absorption, high specific surface area, and effective separation of photo-generated electrons and holes. The study provides insights into the photocatalysis mechanism and demonstrates the potential of these hybrids in environmental remediation.
研究不足
The study focuses on the photocatalytic degradation of specific pollutants (MO and TCH) under visible light, and the stability of the hybrids is tested over a limited number of cycles. The scalability and practical application in real-world conditions are not explored.
1：Experimental Design and Method Selection:
The study involves the synthesis of In2S3/UiO-66 hybrids through a hydrothermal process, aiming to enhance photocatalytic activity under visible light.
2：Sample Selection and Data Sources:
Samples include pure In2S3, UiO-66, and various In2S3/UiO-66 hybrids with different In2S3 content.
3：List of Experimental Equipment and Materials:
Equipment includes PXRD, SEM, TEM, XPS, UV–Vis DRS, PC, PL, and BET analyzers. Materials include zirconium tetrachloride, 1,4-benzendicarboxylic acid, indium nitrate, sodium sulfide, acetic acid, and N,N-dimethylformamide.
4：Experimental Procedures and Operational Workflow:
The synthesis involves hydrothermal processes for UiO-66, In2S3, and their hybrids, followed by characterization and photocatalytic performance evaluation.
5：Data Analysis Methods:
Photocatalytic performance is evaluated by degradation efficiency of MO and TCH under visible light, analyzed using UV–Vis absorbance.
