Abstract

Ag/ZnO nanosheet composites were prepared by zinc nitrate, sodium hydroxide and silver nitrate via a simple hydrothermal method. The crystal structure, morphology, optical property and photocatalytic performance were studied by means of XRD, SEM, HRTEM, XPS, and PL methods. It is found that both the pure ZnO and composite Ag/ZnO samples have the same morphology of nanosheet. The interaction of spherical Ag particles with ZnO matrix in the Ag/ZnO sample leads to an increase in photocatalytic efficiency for the possible increase of concentration of surface hydroxyl and the photo-induced electrons and holes. The addition of Ag can reduce the recombination rate of photo-generated carriers and the sample with addition of 3 at% Ag to ZnO exhibits the best photocatalytic activity with the degradation rate up to 95% within 15 min.

摘要

使用硝酸锌、氢氧化钠和硝酸银为原料, 通过水热法制备出了Ag/ZnO 纳米复合材料; 采用 XRD、SEM、HRTEM、XPS、PL 等表征手段对复合材料的晶体结构、形貌、光学性能和光催化性能 进行了研究。测试结果表明, 纯ZnO 和Ag/ZnO 复合材料具有相同的纳米片形貌; 在Ag/ZnO 样品中, 球状Ag 粒子与ZnO 基体间的相互作用增加了复合材料的表面羟基, 降低了光激发载流子的复合率, 因此提高了光催化效率。而在所有样品中, 添加了3 at%Ag 的样品表现出了最优的光催化性能, 其在 15 min 内光催化降解率达到95%。
