摘要：

采用原位生长法制备Ag₃PO₄/g-C₃N₄异质结催化剂,在可见光照射下,催化氧化降解废水中的药物大分子黄连素。通过X射线衍射（XRD）、扫描电镜（SEM）、X射线光电子能谱（XPS）、紫外-可见漫反射光谱（UV-vis DRS）分析催化剂的组成和结构,并测试了Ag₃PO₄/g-C₃N₄降解黄连素的光催化活性。结果表明：利用可见光照射,g-C₃N₄掺杂量为0.7 g时,Ag₃PO₄/g-C₃N₄对黄连素的光催化降解活性最好,可见光反应15 min降解率达到100%,重复4次实验后降解率降至73.2%,其具有较好的光稳定性。自由基捕获实验证明h⁺和·O₂^-在降解黄连素废水中起主要作用,结合UV-vis DRS分析可知,Ag₃PO₄/g-C₃N₄遵循Z型异质结机理。

Abstract:

Ag₃PO₄/g-C₃N₄ heterojunction catalyst was synthetized by in-situ growth method,and under visible light emission,the degradation of medicine macromolecular berberine in wastewater was catalyzed oxidation.The composition and structure of the catalyst were analyzed by X-ray diffraction（XRD）,scanning electron microscopy（SEM）,X-ray photoelectron spectroscopy（XPS） and ultraviolet visible diffuse reflectance spectroscopy（UV-vis DRS）.The photocatalytic activity of Ag₃PO₄/g-C₃N₄for the degradation of berberine was tested.The results showed that when the doping amount of g-C₃N₄ was 0.7 g,the photocatalytic degradation activity of Ag₃PO₄/g-C₃N₄ for berberine was the best under visible light irradiation.The degradation rate reached 100% after 15 min of visible light reaction.After four repeated experiments,the degradation rate was decreased to 73.2%,which had good light stability.Free radical capture experiments showed that h⁺ and ·O₂ ^- played major role in the degradation of berberine wastewater.Combined with UV-vis DRS analysis,Ag₃PO₄/g-C₃N₄ followed the Z-type heterojunction mechanism.
