| Abstract: | The photocatalytic dehydrogenation of aqueous solution of ethanol on two types of CdS supports with different crystal structures modified by either the chemically deposited Pd or mechanically mixed Pt was investigated.The crystal structural morphology of the CdS semiconductor powders was determined by TEM and XRD.The relationship between the CdS crystal 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. |
