摘要
Guth等人[1]在1977年首次报道了铁(Ⅲ)掺杂二氧化钛催化剂对氮气光催化还原为氨具有独特的光催化效果,开辟了一条太阳能转化为化学能的新途径,引起了人们对铁(Ⅲ)掺杂二氧化钛的研究热潮[2~7].
A series nanocrystalline iron and silicon doped TiO2 was prepared as single-phase product by a new sol-gel technique. The results of XRD and TEM reveal that pure and iron-doped titanium dioxide nano-particles show a rapid increasing of grain growth at high temperature, while the grain growth of iron and silicon doped specimens was restrained drastically, exhibiting very good thermal stability. The phase transition temperature of anatase-to-rutile is progressively increased in iron and silicon doped samples and the higher the silicon content, the higher the phase transition temperature.
