摘　　要：近些年来,TiO_(2)半导体材料在环境治理及能源转化领域受到了广泛关注,TiO_(2)拥有很多优点,例如它的催化活性很高,而且化学性质非常稳定,并且成本很低。因为TiO_(2)有较大的禁带宽度,并且电子-空穴对有比较高的再复合率,这就导致TiO_(2)对于太阳光的利用率较低。提升TiO_(2)半导体材料对太阳光的利用率成为当前的研究热点。综述了通过对TiO_(2)改性制备催化剂的方式以及TiO_(2)在生活中的应用实例。In recent years,TiO_(2) semiconductor materials have received extensive attention in the fields of environmental governance and energy conversion. TiO_(2) has many advantages, such as high catalytic activity, very stable chemical properties and low cost. Because TiO_(2) has a large forbidden band width and electron-hole pairs have a relatively high recombination rate, the utilization rate of TiO_(2) for sunlight is low. How to improve the utilization of TiO_(2) semiconductor materials to sunlight and promote the rapid separation of electron-hole pairs has become a current research focus. In this article, the methods of preparing catalysts by modifying TiO_(2) and the application examples of TiO_(2) in daily life were reviewed.
