Synthesis and Characterization of Nickel-Manganese Oxide Catalysts for the Complete Oxidation of Toluene
Abstract
Binary nickel–manganese oxide catalysts were synthesized via a co-precipitation method and evaluated for the complete oxidation of toluene, a representative volatile organic compound (VOCs). The structural, morphological, textural, and redox properties of the catalysts were systematically characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), nitrogen adsorption–desorption isotherms, and H₂ temperature-programmed reduction (H₂-TPR). The nickel manganese oxide catalysts exhibit multiphase structures mainly composed of MnO₂, NiMnO₃, NiMn₂O₄, and Mn-doped NiO, along with a significantly higher specific surface area and pore volume compared to MnOₓ and NiO. Catalytic tests demonstrate that the NiMn₂Oₓ catalyst shows superior activity, achieving complete oxidation of toluene at 273 °C and exhibiting the lowest T₅₀ and T₉₀ values (237 °C and 248 °C, respectively) among the tested catalysts. The enhanced catalytic performance is attributed to the synergistic interaction between Ni and Mn species, which induces lattice distortion and enhances reducibility. These results highlight the potential of binary Ni–Mn oxide composite catalyst as an efficient and cost-effective material for VOCs abatement.Downloads
