研究目的
To investigate the photocatalytic degradation of tetracycline hydrochloride (TC·HCl) using a novel rugby-like β-Ga2O3 with 3D hierarchically assembled porous structures under UV-light irradiation.
研究成果
The rugby-like β-Ga2O3 with 3D hierarchically assembled porous structures exhibited superior photocatalytic activity for TC·HCl degradation under UV-light irradiation, attributed to its large specific surface area, intrinsic electronic properties, and stable structure. The study provides a promising strategy for designing photocatalysts for environmental remediation.
研究不足
The study focuses on the photocatalytic degradation under UV-light irradiation, and the performance under visible light or other conditions is not explored. The scalability and practical application of the synthesis method may require further investigation.
1：Experimental Design and Method Selection:
A facile precipitation-calcination method was used to synthesize rugby-like β-Ga2O3 with 3D hierarchically assembled porous structures. The photocatalytic activity was evaluated by the degradation of TC·HCl under UV-light irradiation.
2：Sample Selection and Data Sources:
Commercial β-Ga2O3 was used as the precursor. The effects of calcination temperature on photocatalytic activity were discussed.
3：List of Experimental Equipment and Materials:
Microwave digestion apparatus, muffle furnace, UV-vis spectrophotometer, LC-QTOF-MS, etc.
4：Experimental Procedures and Operational Workflow:
The synthesis involved precipitation followed by calcination at different temperatures. Photocatalytic activity measurements were conducted under UV-light irradiation, and intermediates were identified by LC-QTOF-MS.
5：Data Analysis Methods:
The photocatalytic degradation data were analyzed using pseudo-first-order kinetics model. The intermediates were identified based on LC-QTOF-MS analysis.
