设计了一条两步路线成功合成了Ag纳米粒子点缀的ZnO花状微结构(Ag/ZnO).首先以六水合硝酸锌、尿素和L-半胱氨酸为反应原料,100°C下水热反应8h,合成出花状碱式碳酸锌前驱体,并经空气中高温煅烧得到多孔ZnO花状微结构;然后,通过光还原硝酸银得到了Ag/ZnO花状微结构.所得产物用X-射线衍射仪、扫描电子显微镜、透射电子显微镜、热重分析仪、红外光谱、紫外-可见漫反射光谱和荧光光谱等进行系统的表征.研究显示,所得的Ag/ZnO花状微结构在光催化、灭菌和电催化等领域都具有很好的应用.
A two-step route was successfully designed to fabricate ZnO flower-like microstructures (Ag / ZnO) decorated with Ag nanoparticles.Firstly, zinc nitrate hexahydrate, urea and L-cysteine were used as reaction materials, 8h, the flower-like basic zinc carbonate precursors were synthesized and calcined at high temperature in air to obtain porous ZnO flower-like microstructure; then Ag / ZnO flower-like microstructure was obtained by photoreduction of silver nitrate.The resulting product was characterized by X-ray The results show that the obtained Ag / ZnO flower-like microstructures have the best performance in photocatalysis, photocatalysis, UV-Vis, Sterilization and electrocatalysis and other fields have a good application.
