A highly efficient and energy-saving photothermal synergistic catalytic oxidation technology was developed to eliminate ethyl acetate (EA) and 1,2-dichloroethane (1,2-DCE) over MoO_x–TiO₂, derived by MIL-125(Ti), supported Ru catalysts (Ru/MoO_x–TiO₂). The introduction of MoO_x enhanced the light absorption capacity, carrier separation capacity and redox capacity of the catalyst, thus significantly improving the photothermal synergistic catalytic performance, with Ru/MoO_x–TiO₂ exhibiting outstanding activity for EA and 1,2-DCE oxidation (T_90% = 212 and 319 ℃, respectively). Meanwhile, the abundant Brønsted acidic sites on Ru/MoO_x–TiO₂ were inclined to generate more HCl and CO₂, and reduce the release of chlorine-containing byproducts than that over Ru/TiO₂. The characterization results by the in situ XPS, in situ PL and in situ EPR exhibited that the improvement of the photothermal synergistic catalytic oxidation performance was attributed to the coupling effect between electron migration on the catalyst surface and active oxygen species during the photothermal synergistic catalytic reaction process. This work has provided a promising path for simultaneously enhancing the removal efficiency of multi-component VOCs and the selectivity of target products.
