Abstract

Different weight contents of AgBr nanoparticles supported on hierarchical ZnO nanostructure flowers were synthesized by precipitation-deposition method at room temperature. The nanocomposites were investigated for photocatalytic degradation of methylene blue (MB) under ultraviolet (UV)-visible light irradiation. The analytical results show that AgBr nanoparticles with size range of 60–80 nm were supported on hierarchical ZnO nanostructure flowers with ∼4 µm diameter. The photodegradation was improved by AgBr nanoparticles loaded on ZnO nanopetals. In this research, 10 wt% AgBr–ZnO nanocomposites have the highest photodegradation of MB under UV-visible light irradiation.

在室温下通过沉淀-沉积法合成了不同重量含量的负载在分级ZnO纳米结构花上的AgBr纳米颗粒。研究了纳米复合材料在紫外（UV）-可见光照射下对亚甲基蓝（MB）的光催化降解。分析结果表明，大小为60-80 nm的AgBr纳米颗粒被直径约4 µm的分层ZnO纳米结构花所支撑。负载在ZnO纳米花瓣上的AgBr纳米颗粒改善了光降解性能。在这项研究中，10％（重量）的AgBr-ZnO纳米复合材料在紫外-可见光照射下具有最高的MB光降解性能。
