| Summary: | Heterogeneous chemical oxidation is a promising technique and effective treatment in degrading dye-contaminated wastewater which generated highly oxidizing radicals such as hydroxyl (˙OH) radicals. Perovskite is a potential decent ceramic metal oxides catalyst with the general formula of ABxB’yO3 has been applied as a heterogeneous catalyst for dye-contaminated wastewater degradation under ambient conditions with and without the aid of oxidants. Substitution of B-site cation plays a crucial role in modulating the overall catalytic performance of the perovskite rather than A-site cation. Despite its high catalytic performance, these catalysts suffered severe leaching problem during heterogeneous catalysis. Therefore, substitution of alternative B-site metal cations in perovskite to minimize the leaching problem while maintaining adequate catalytic performance is critical. However, the substitution of molybdenum as an active phase for B-site cation within the perovskite structure is still scanty. |
