摘要:
通过水热法, TiO2 纳米棒生长在片状导电云母核体表面成功合成了TiO2 纳米棒/导电云母复合材料(TiO2 NRA/C-mica)。为提高TiO2 NRA的光响应能力, 通过溶液浸渍法在TiO2 NRA上负载硫化镉纳米粒子(CdS NPs)制备出CdS修饰TiO2 NRA/C-mica复合材料。通过XRD,SEM,UV-Vis,PL和光电化学等技术对所制得的复合材料进行表征。结果表明, CdS NP均匀负载于TiO2 NRA上形成了异质结构, 有效拓宽了TiO2 NRA/C-mica的可见光响应范围和光生电子-空穴的分离效率; CdS NP(8)/TiO2 NRA/C-mica具有较佳的光电化学性能。与TiO2 NRA/C-mica相比, CdS NP(8)/TiO2 NRA/C-mica复合材料的光电流密度提高0.9倍, 电位降高出300 mV(vs. SCE), 对304不锈钢具有优异的光阴极保护性能和防腐效果。
Abstract:
TiO2 nanorod arrays(TiO2 NRA)were grown on the conductive mica(C-mica)by the hydrothermal method to successfully prepare TiO2 NRA/C-mica. For the enhancement of the light response capacity of TiO2 NRA, CdS nanoparticles(CdS NPs)were further loaded on the surface of TiO2 NRA by the solution impregnation to fabricate CdS NP modifed TiO2 NRA/C-mica. The obtained samples were characterized by XRD, SEM, UV- Vis, PL and photochemical techniques. The results show that CdS NPs are uniformly loaded on the surface of TiO2 NRA to generate heterostructure, which effectively broadens the response range of the visible light and improves the separation efficiency of the photo-induced electron-hole for CdS modifed TiO2 NRA/C-mica. The obtained composites impregnated 8 times have better photoelectrochemical performance. The photocurrent density of CdS NP(8)/TiO2 NRA/C-mica increases by 0.9 times and the potential drop is 300 mV(vs.SCE)higher than those of TiO2 NRA/C-mica. CdS NP(8)/TiO2 NRA/C-mica is found to possess excellent photocathodic protection and anticorrosion for the 304SS.
