摘　　要：总结了CO2 光催化还原反应中催化剂的应用 ,主要涉及TiO2 、CdS以及铁氧化物 ,由于它们自身在反应中存在着一定的缺陷 ,因而在应用中往往需要对其进行改性 ,以改变其电子结构和光响应特性 ,从而提高反应的光催化效率。另外 。The application of photocatalysts in the photocatalytic reduction of carbon dioxide, including TiO 2, CdS and iron oxides was reviewed. Because of some inherent shortcomings,for the catalytic reaction these catalysts were changed their oxidation-reduction potential and photo absorption characteristics through modification to increase their photocatalytic activity and selective capacity, and meanwhile, the solar energy could be used more efficiently. The mechanisms for the process of reactions were slao introduced.
