Abstract

A BSTRACT TiO 2 nanoparticles synthesized by the sol-gel method and modiﬁed by annealing in air and hydrogen atmospheres were studied by surface photovoltage spectroscopy (SPS). SPS measurements showed that the modiﬁed in air TiO 2 nanoparticles have a more intense signal than those treated in hydrogen. A linear correlation was found between the SPS and the diffuse reﬂectance spectra of the samples.

TiO2溶胶-凝胶纳米颗粒的诱导表面光电压

采用表面光电压谱(SPS)研究了溶胶-凝胶法合成的二氧化钛纳米颗粒，并在空气和氢气气氛中进行了退火修饰。SPS测量表明，在空气中修饰的二氧化钛纳米粒子比在氢气中修饰的二氧化钛纳米粒子具有更强的信号。SPS与样品的漫反射光谱呈线性相关。
