Paper Abstract
Nanocomposites of ZnO with p-type NiO and n-type SnO2 in the equimolar ratio were prepared by microwave assisted method inorder to reduce the fast recombination rate of ZnO. XRD reveals the formation of nanocomposites of ZnO. The photocatalytic activity of nanocomposites against RhB is poor compared to control ZnO. The control ZnO nanocrystals exhibit 100% degradation efficiency and is mainly ascribed to the decrease in band gap and increase in surface defects. The decolorization of RhB follows the pseudo-first order kinetics and the mechanism is explained on the basis of charge trapping through defect sites.
