摘要

采用简易研磨法将Ag₃PO₄颗粒负载在纳米片组装的BiOI微球表面,制备出p-n型Ag₃PO₄/BiOI异质结光催化剂。利用不同表征手段对Ag₃PO₄/BiOI复合材料的物相、形貌、化学组成和光学吸收特性进行了分析,并探索了其在可见光下光降解盐酸金霉素(CTC)的性能。结果表明:AB-2(Ag₃PO₄与BiOI质量比为1∶2)表现出最高的光降解CTC活性,可见光照射75min后AB-2对CTC(20mg/L)的去除率为79.2%,高于单一Ag₃PO₄与BiOI光催化剂。此外,AB-2光催化剂在循环使用5次后对CTC的去除率为70.3%,具有较好的重复使用性。p型BiOI和n型Ag₃PO₄构成p-n型异质结结构,促进了光生电子和空穴的有效分离,进而降低了电子-空穴对的复合效率,提升了Ag₃PO₄/BiOI复合材料的光催化活性。

Abstract

Ag₃PO₄ particles were loaded onto the surface of BiOI microspheres assembled from nanoflakes by a simple grinding method to prepare a p-n type Ag₃PO₄/BiOI heterojunction photocatalyst.The phase,morphology,chemical composition,and optical absorption properties of the Ag₃PO₄/BiOI composites were analyzed using various characterization techniques,and its performance in visible light-induced degradation of chlortetracycline hydrochloride (CTC) was explored.The results showed that the AB-2 (mass ratio of Ag₃PO₄ to BiOI of 1∶2) exhibited the highest CTC degradation activity,with a removal efficiency of 79.2% for CTC (20mg/L) under visible light irradiation for 75 minutes,which was higher than that of the Ag₃PO₄ and BiOI photocatalysts alone.In addition,the AB-2 photocatalyst had a removal efficiency of 70.3% for CTC after five cycles of reuse,showing good repeatability.The p-type BiOI and n-type Ag₃PO₄ formed a p-n type heterojunction structure,which promoted the effective separation of photogenerated electrons and holes,thereby reducing the recombination efficiency of electron-hole pairs and enhancing the photocatalytic activity of the Ag₃PO₄/BiOI composites.
