研究目的
To demonstrate the viability of a ZnO/TiO2/Ag2Se thin-film composite for the degradation of naproxen in aqueous solutions by visible-light photoelectrocatalysis.
研究成果
The study confirmed the viability of the FTO/ZnO/TiO2/Ag2Se thin-film photoanode for the efficient degradation of naproxen in water under visible-light photoelectrocatalysis. The process showed synergistic effects between light irradiation and current supply, with the degradation rate influenced by the drug concentration and the presence of chloride ions.
研究不足
The study did not evaluate the change of total organic carbon content over time due to its very low initial value. Additionally, the formation of recalcitrant chloro-derivatives in chloride media was noted as a potential limitation.
1：Experimental Design and Method Selection:
The study involved the synthesis of a ZnO/TiO2/Ag2Se thin-film composite on FTO for photoelectrocatalytic degradation of naproxen under visible light.
2：Sample Selection and Data Sources:
Solutions containing 5 mg L-1 naproxen and 50 mM Na2SO4 at natural pH were used.
3：List of Experimental Equipment and Materials:
A cell equipped with a Pt wire cathode, the composite photoanode, and a 36 W blue LED lamp.
4：Experimental Procedures and Operational Workflow:
The degradation process was monitored over time under specific electrochemical and photochemical conditions.
5：Data Analysis Methods:
The degradation kinetics were analyzed using pseudo-first-order reaction models, and by-products were identified using LC-QToF-MS.
