在这项工作中，可见光驱动的等离激元光催化剂，Ag-AgBr/BiVO4 纳米结构通过水热法、表面活性剂沉积沉淀法和随后的光驱动路线轻松制备。作为一种低成本、高效的可见光驱动光催化剂，BiVO4 被选为理想的载体。十六烷基三甲基溴化铵（CTAB）用作表面活性剂、模板导向剂和溴源。所得Ag-AgBr/BiVO4光催化剂表现出优异的可见光驱动光催化性能。在可见光照射下，16分钟内可分解罗丹明B（RhB）。同时，与其他VLD（可见光驱动）光催化剂如Ag-AgBr、Ag-TiO2和AgBr-Ag-TiO2复合材料相比，Ag的用量和成本显着降低。此外，还研究了 Ag-AgBr/BiVO4 纳米结构可能的光催化机制。
In this work, visible light driven plasmonic photocatalyst, Ag–AgBr/BiVO4 nanostructures have been facilely prepared by a hydrothermal process, the deposition precipitation method with surfactant and subsequent light driven route. As a low cost and efficient visible light driven photocatalyst, BiVO4 is chosen as an ideal support. Cetyltrimethylammonium bromide (CTAB) was used as both of the surfactant, template directing reagent and the Br source. The obtained Ag–AgBr/BiVO4 photocatalyst shows excellent visible light driven photocatalytic performance. It can decompose Rhodamine B (RhB) within 16 min under visible light irradiation. Meanwhile, compared with other VLD (visible light driven) photocatalysts such as Ag–AgBr, Ag–TiO2 and AgBr–Ag–TiO2 composite, the amount of Ag needed as well as the cost decrease significantly. Moreover, the possible photocatalytic mechanism of the Ag–AgBr/BiVO4 nanostructures was investigated.
