摘要: 本文研究了在乙腈溶剂中硫化镉粉末光催化氧化反,反-1,4-二苯基-1,3-丁二烯的反应。认为反应历程是经负氧离子(O2·-)与底物正离子自由基反应进行。发现水、二氧化钛、亚硫酸钠对反应有促进作用,讨论了其影响反应的原因。认为可通过加入电子转移物质减少半导体光生电子-空穴对的复合来提高半导体光催化效率。

Abstract: The photocatalytic oxidation reaction of 1,4-biphenylbutadiene on CdS powder in acetoni-trile was studied and it was found that water, TiO2, and sodium sulfite could promote the reaction. The possible mechanisms were discussed. Based on these investigations it is suggested that the methods to decrease the recombination of electron/hole pairs may increase the semiconductor photocatalytic yield.
