The catalytic degradation of methylene blue (MB), an organic dye, in the presence of these materials and hydrogen peroxide (H2O2) as a green oxidant was studied at room temperature. The effects of solution pH, catalyst composition and radical scavenging agents on the degree of degradation of MB were also studied. Finally, the recoverability and reusability of the V-doped ZrO2 catalyst were analysed.
