Abstract:
3D porous flower-like ZnO micro/nanostructure films grown on Ti substrates are synthesized via a very facile electrodeposition technique followed by heat treatment process. The ZnO architecture is assembled with ultra thin sheets, which consist of numbers of nanoparticles and pores, and the size of the nanoparticles can be controlled by adjusting the electrodepo-sition time or calcination temperature. It is worth noting that this synthetic method can provide an effective route for other porous metal oxide nanostructure films. Moreover, the photocatalytic performance shows the porous ZnO is an ideal photocatalyst.

摘要:
采用电沉积及后续的热处理技术,在Ti衬底上合成了一种三维多孔花状ZnO微纳结构薄膜. 这种ZnO结构是由包含大量纳米颗粒和孔洞的纳米薄片组成,纳米颗粒的大小可以通过调节电沉积时间和煅烧温度控制. 光催化性能的测试表明这种多孔ZnO薄膜是一种理想的光催化剂.
