Enhancement of Photocatalytic Properties of TiO2/CdS nanoparticles/ graphene composite for waste water processing

A new type of TiO2/CdS decorated Graphene photocatalysts were prepared by solution-based method. The catalytic activity of the prepared nanocomposites for the photocatalytic degradation of acid orange 7 was measured. X-ray diffraction, scanning electron microscopy and and UV–vis diffuse reflectance spectroscopy were used to investigate the structure, and the optical absorbance. The broad peaks in the XRD patterns indicate that the TiO2/CdS nanoparticles were about 35 nm. The results showed that Graphene could enhance the activity of the TiO2/CdS photocatalyst
