CdSe纳米颗粒敏化的TiO2纳米棒阵列的制备及其光电和光催化性能
Preparation and Photoelectrochemical and Photocatalytic Performance of CdSe Nanoparticle Sensitized TiO2 Nanorod Arrays
摘要
Abstract
CdSe is a kind of semiconductor materials with visible light response.Sensitizing TiO2 with CdSe can make composite ma-terial possessing visible light absorption and efficiently promote separation of photogenerated charges.In this work,TiO2 nanorod arrays were first synthesized on fluorine-doped tin oxide (FTO)with a hydrothermal method.CdSe nanoparticles were then deposited on TiO2 nanorod arrays by a successive ionic layer adsorption and reaction method.At last,CdSe nanoparticle sensitized TiO2 nanorod arrays were obtained and characterized.Experimental results showed that CdSe nanoparticle sensitized TiO2 nanorod arrays exhibited enhanced visible light absorption,and its photocurrent density was 10 times as high as that of pure TiO2 nanorod arrays.The photo-catalytic degradation rate of methylene blue over CdSe nanoparticle sensitized TiO2 nanorod arrays increased by 85% and 75%,sepa-rately compared to that of methylene blue self-degradation and pure TiO2 nanorod arrays.关键词
