Three-dimensional ZnO nanoflower has been synthesized via microwave irradiation technique using glycine as complexing/capping agent for the first time. TEM, SAED, XRD, FTIR, UV and PL spectra have been recorded to characterize the synthesized ZnO nanostructures. The TEM image indicates the formation of 3D flower-like ZnO nanostructures having diameter ~0.74-1.60 μm. The spacing between adjacent lattice fringes obtained from the HRTEM image is 0.145 nm which indicated the presence of (103) lattice plane of ZnO. The synthesized ZnO nanoflower show excellent luminescence properties. The photocatalytic properties of synthesized ZnO nanoflower is depicted by the degradation of Eosin Y dye under solar irradiation. It is found that 98.9% of Eosin Y dye is degraded within 50 min under solar irradiation. Henceforth, ZnO nanoflower acts as an effective photocatalyst for the degradation of Eosin Y dye.

微波辅助合成 3D 花状 ZnO 纳米结构以增强光催化降解/去除水中曙红 Y

首次使用甘氨酸作为络合剂/封端剂,通过微波辐射技术合成了三维 ZnO 纳米花。已记录 TEM、SAED、XRD、FTIR、UV 和 PL 光谱以表征合成的 ZnO 纳米结构。TEM 图像表明形成了直径约 0.74-1.60 μm 的 3D 花状 ZnO 纳米结构。从 HRTEM 图像中获得的相邻晶格条纹之间的间距为 0.145 nm,这表明存在 ZnO 的 (103) 晶格平面。合成的 ZnO 纳米花显示出优异的发光性能。合成的 ZnO 纳米花的光催化性能通过日光照射下曙红 Y 染料的降解来描述。结果表明,在阳光照射下 50 分钟内,98.9% 的曙红 Y 染料被降解。今后,
