摘要
光催化还原CO2既是光能利用的一种有效途径,又可将煤炭、石油和天然气等化石燃料排放的CO2作为碳源,变废为宝,极具经济价值。结合国内外光催化还原二氧化碳研究成果,从光催化还原二氧化碳机理出发,分别探讨了光源、光反应器、添加剂、光照时间、光催化剂等因素对光催化还原二氧化碳的影响;认为高效光催化剂的开发,优良光催化反应器的研制以及更深的机理探索,对该领域的研究至关重要。
Photocatalytic reduction of CO2 is not only an effective method for solar energy utilization,but also a fairly good way to convert CO2 emitted by combustion of fossil fuels such as coal,oil and natural gas to useful carbon sources.Based on relevant researches both in China and abroad,the effects of light sources,photocatalytic reactors,additives,irradiation time and photocatalysts on photaocalaytic reduction of CO2 are discussed from the mechanim of photocatalytic teduction of CO2.It is discovered that the development of effcient catalysts,manufacturing of fine photocatalytic reactors and more thorough exploration of photocatalytic mechanism are of vital importance for the research in this field.
