摘要 通过电化学沉积法以TiO2纳米管阵列(TNTs)为基底制备CdSe/TiO2异质结薄膜。研究TiO2纳米管阵列基底不同退火温度(200,350,450,600℃)对CdSe/TiO2异质结薄膜光电化学性能的影响。采用SEM,XRD,UV-Vis,电化学测试等方法对样品的微观形貌、晶体结构、光电化学性能等进行表征。结果表明:立方晶型的CdSe纳米颗粒均匀沉积在TiO2纳米管阵列管口及管壁上。TiO2纳米管阵列未经退火及退火温度为200℃时,为无定型态,在TiO2纳米管阵列上沉积的CdSe纳米颗粒数量少,尺寸小,异质结薄膜光电性能较差,光电流几乎为零。随着退火温度升高到350℃,TiO2纳米管阵列基底开始向锐钛矿转变;且沉积在TiO2纳米管上的CdSe颗粒增多,尺寸增大,光电化学性能提高。退火温度为450℃时光电流值达到最大,为4.05mA/cm2。当退火温度达到600℃时,TiO2纳米管有金红石相出现,CdSe颗粒变小,数量减少,光电化学性能下降。

Abstract:CdSe/TiO2 heterojunction thin films were prepared by electrodeposition of CdSe nanoparticles on TiO2 nanotube arrays(TNTs). The effect of annealing temperature of TNTs (200,350,450,600℃) on photoelectrochemical properties of CdSe/TiO2 heterojunctions thin films was discussed. The microstructure, crystal structure and photoelectric chemical properties of the samples were characterized by SEM, XRD, UV-Vis, electrochemical test and other methods. The results show that the cubic CdSe nanoparticles are uniformly deposited on the nozzles and walls of TNTs. When TNTs is amorphous without annealing or with annealing at 200℃, CdSe nanoparticles deposited on TNTs appear with less quantity and smaller size. The photoelectrochemical properties of CdSe/TiO2 heterojunctions thin films is very poor, and photocurrent density value almost reaches zero. As the annealing temperature increasing to 350℃, anatase phase is observed in TNTs. Consequently, CdSe nanoparticles show more quantity and lager size. Furthermore, the photoelectrochemical performance improves. The photocurrent density reaches the maximum value 4.05mA/cm2 at the annealing temperature of 450℃. However, when the annealing temperature continually increases to 600℃, rutile phase is formed in TNTs, CdSe nanoparticles become small and few and the photoelectrochemical performance decreases.
