• • K+ doping in MnOx enhances oxygen vacancy concentration, lowering toluene oxidation T90 by ~20°C (from 250°C to 230°C) as reported by Huang et al. (2024), improving low-temperature activity for industrial off-gas treatment.
• • CoMn2O4 catalysts exhibit dual activation of lattice and molecular oxygen via oxygen vacancies, achieving >90% VOC conversion at 220°C (Ren et al., 2024), enabling energy-efficient combustion.
• • Cu-OMS-2 materials, characterized by XAS and cyclic voltammetry (Ramstad & Mikkelsen, 2004), show enhanced redox properties, with Cu incorporation increasing oxygen mobility and lowering activation energy for aromatic VOC oxidation.
• • Pt/MnO2 catalysts with strong metal-support interactions achieve total toluene oxidation at 150°C (Mo et al., 2019), demonstrating that noble metal loading on MnO2 drastically reduces operating temperature, improving cost-effectiveness despite Pt cost.
