摘要

通过修饰两个半导体之间的金属元素物质，可以构建间接的z型异质结，提高光生电荷的分离效率，而贵金属量子点（QDs）可以提供表面等离子体共振（SPR）效应，扩大复合材料的光吸收范围和能力。采用简单的共沉淀法和光还原法制备了三维枝状ZnO/Ag-QDs/AgCl光催化剂。制备的材料在模拟日光和自然光下对MB、RhB、CR、MO和NOR均实现了完全降解。优异的光催化性能可归因于z型异质结、SPR效应和大的比表面积。该研究为构建z型异质结和光催化过程中活性物质的调节提供了新的策略。

Preparation of dendritic ZnO/Ag-QDs/AgCl photocatalysts and its photodegradation of organic dyes and antibiotics

By modifying metallic elemental substance between two semiconductors can construct indirect Z-type heterojunction to improve the separation efficiency of photogenerated charges, while noble metal quantum dots (QDs) can provide surface plasmon resonance (SPR) effect to broaden the range and ability of light absorption of composite. 3D dendritic ZnO/Ag-QDs/AgCl photocatalyst was successfully prepared using a simple co-precipitation and photoreduction method. The prepared material achieved complete degradation of MB, RhB, CR, MO and NOR under simulated sunlight and natural light. The excellent photocatalytic performance can be attributed to the Z-type heterojunction, the SPR effect and the large specific surface area. This study provides a new strategy for constructing Z-type heterojunctions and modulating active species in photocatalytic processes.
