摘　　要：文章研究了水对乙腈溶液中光催化还原CO2反应性能的影响。证明在相同的实验条件下,水能极大地提高乙腈体系中光催化还原CO2的效率;结果显示,水的体积占总体积10%时具有最佳的催化效果。另外,本研究对水对体系粘度和电导率影响进行测试,初步讨论了它们对光催化还原CO2反应中的影响。The effect of water on the photocatalytic CO2 reduction in reaction medium of acetonitrile was presented in the paper. We found that water had a remarkable promotion effect on the reaction rate in acetonitrile system under uniform reaction conditions, and the optimal volume ratio of water was obtained at 10 % in this system. In addition, the property of viscosity and conductivity were also studied in this paper, and the possible mechanism of water influence on the photoeatalytic CO2 reduction was primary discussed.
