摘要
CO_(2)的过度排放是导致温室效应的主要原因,同时CO_(2)也是潜在的碳能源。本文综述了以二氧化钛基催化材料在光催化条件下还原CO_(2)的研究进展。首先对TiO_(2)微纳米材料的制备以及还原CO_(2)的机理进行讨论;其次介绍了利用半导体复合、贵金属沉积、金属离子掺杂和非金属掺杂等方法来改性TiO_(2)以增强光催化还原性能。
Excessive CO_(2)emissions are the main cause of the greenhouse effect,and CO_(2)is also a potential carbon energy source.The research progress on the reduction of CO_(2)with titanium dioxide-based catalytic materials under photocatalytic conditions was reviewed.The preparation of TiO_(2)micro-nano materials and the mechanism of CO_(2)reduction were discussed.The use of semiconductor compounding,precious metal deposition,metal ion doping and non-metal doping to modify TiO_(2)was introduced to enhance the photocatalytic reduction performance.
