摘要： 有关醇类水溶液光催化贮能脱氢反应研究大多集中在提高半导体TiO2和CdS表面修饰组分的光催化活性[1～3]及考察TiO2半导体晶体结构与光催化性能的关系上[4,5],CdS半导体晶体结构形态对光催化性能的影响尚未见报道.本文在这方面进行了一些有益的研究.

Abstract: The photocatalytic dehydrogenation of aqueous solution of ethanol on two types of CdSsupports with different crystal structures modified by either the chemically deposited Pd or mechanically mixed Pt was investigated.The crystal structural morphology of the CdSsemiconductor powders was determined by TEMand XRD.The relationship between the CdScrystal structural morphology and the dehydrogenation behavior of the catalysts was illustrated and the fact that the photocatalytic dehydrogenation of aqueous solution of ethanol is quite sensitive to the crystal structural morphology of catalyst support was confirmed.

Key words: Photocatalysis, Dehydrogenation, Crystal structural morphology
