CdO-CdS nano-composites as improved photo-catalysts for the generation of hydrogen from water
CdO-CdS nanocomposites were prepared by polyol method followed by heating at 300°C. XRD study confirmed the atomic scale mixing of CdO and CdS nanoparticles, leading to the formation of CdSO3 phase at the interfacial region between CdO and CdS. The enhancement in photo-catalytic activity for hydroge...

| description | CdO-CdS nanocomposites were prepared by polyol method followed by heating at 300°C. XRD study confirmed the atomic scale mixing of CdO and CdS nanoparticles, leading to the formation of CdSO3 phase at the interfacial region between CdO and CdS. The enhancement in photo-catalytic activity for hydrogen generation from water is observed in case of CdO-CdS nanocomposites compared to individual CdS and CdO nanoparticles. Based on XRD, steady state and time resolved luminescence studies and surface area measurements, it is determined that, the fine mixing of CdS and CdO, higher surface area of the composite sample and increase in lifetime of the charge carriers are responsible for the observed increase in hydrogen yield from water when composite sample was used as the photo-catalyst compared to individual components. |
