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.
