摘要:
针对磷酸银(Ag3PO4)和羟基氧化铁(α-FeOOH)等材料因光生载流子复合速率过快而导致光催化性能差的问题，通过制备α-FeOOH与Ag3PO4的异质结复合材料（α-FeOOH@Ag3PO4）来促进光生载流子的分离，从而提升材料的光催化性能。首先采用简单的水热法制备由纳米片组成的具有分级结构的α-FeOOH微球，然后使用原位沉积工艺将Ag3PO4颗粒均匀沉积在α-FeOOH微球表面，制备得到α-FeOOH@Ag3PO4；分析所得异质结复合材料的微观结构、光吸收性能、亚甲基蓝降解性能和光电性能。结果表明：具有分级结构的α-FeOOH微球有利于Ag3PO4颗粒沉积，Ag3PO4颗粒粒径为3~8 nm；α-FeOOH@Ag3PO4吸收边发生红移，光电性能显著增强；α-FeOOH@Ag3PO4的光催化效率是α-FeOOH的75.0倍，是Ag3PO4的1.8倍；α-FeOOH@Ag3PO4是Type-Ⅱ型半导体异质结，光生载流子在异质结界面有效分离，提高了光催化效率和材料的稳定性。α-FeOOH@Ag3PO4具有较强的光催化活性，在光催化治理水污染领域有着广阔的应用前景。
