Analysis of Factors Affecting Photocatalytic Reduction of CO_2

Photocatalytic reduction of CO2is not only an effective method for solar energy utilization,but also a fairly good way to convert CO2emitted 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 photocatalytic reduction of CO2 are discussed from the mechanism of photocatalytic reduction of CO2.It is discovered that the development of efficient catalysts,manufacturing of fine photocatalytic reactors and more thorough exploration of photocatalytic mechanism are of vital importance for the research in this field.
