利用溶胶-凝胶法及光沉积法制备纳米金-钛酸锌(Nano Au-ZnTiO3)复合等离子光催化剂.采用X射线衍射(XRD)、场发射扫描电子显微镜(FE-SEM)、紫外可见漫反射光谱、荧光光谱、光电流密度、光催化制氢性能等技术手段和测试表征了样品的结构及性能.结果表明,ZnTiO3在900℃煅烧下呈立方相和六角相的混合相,其形貌呈近似球形,粒径约为50 ～ 100 nm.由于纳米金(Nano Au)的表面等离子共振效应,Nano Au-ZnTiO3复合材料在可见光区有较强的吸收,吸收峰位于525 nm处.Nano Au-ZnTiO3复合等离子光催化剂在可见光激发下呈现出优良的光催化分解水制氢活性.
