Highly Efficient Photocatalysis by Zinc Oxide-Reduced Graphene Oxide (ZnO-rGO) Composite Synthesized via One-Pot Room-Temperature Chemical Deposition Method

Figure 5

(a) The characteristic peaks for graphene oxide (), reduced graphene oxide (), and water intercalated between graphene sheets () with increasing zinc content are shown. The spectra for samples ZG2 to ZG5 have been magnified for clarity, as indicated by the numbers on the rightmost part. (b) The characteristic spectra for zinc oxide exhibit a hexagonal wurtzite structure. The peaks for zinc precursor are also present.
