摘要
近年来,氢化TiO_2因其独特的光电性质,在光催化、微波吸收、燃料电池等领域具有潜在的应用价值[1]。光催化还原CO2能够实现可再生能源作用下碳资源的大循环,对解决能源与环境污染危机具有重要的科学意义。但有关氢化TiO_2在光催化还原CO_2方面的研究至今未见报道。本实验利用溶剂热法制备出暴露{001}晶面的锐钛矿型TiO_2纳米片,研究发现氢化处理的纳米片具有比氢化前的纳米片和P25更强的光催化还原CO_2性能。
Recently, due to its unique optical and electrical properties, hydrogenated TiO_2 has potential applications[1] in many areas, such as catalysis, microwave absorption, fuel cell. Photocatalytic reduction of CO_2 to achieve the role of renewable energy sources of carbon cycle, has an important scientific significance in relieving the pressure of the energy crisis and phasing down the environmental pollution. But photocatalytic CO_2 reduction of hydrogenated TiO_2 has not been reported. Anatase TiO_2 nanosheets with exposed {001} surfaces were prepared, and it is found that hydrogenated TiO_2 nanosheets has enhanced photocatalytic performance on CO_2 reduction, compared with non-hydrogenated TiO_2 and P25.
