The inhibitory interactions among various volatile organic compounds (VOCs) during combustion in industrial exhaust gases pose a significant challenge for catalytic technologies, primarily due to lack of effective approaches counter these adverse effects. interaction between Pt and TiO2 was readily tuned through hydrogen reduction the matrix (Pt/TiO2-800), which ultimately transformed effect into synergistic toluene-acetone mixture. Optimal activity achieved at 0.6 wt % loading, with 0.6Pt/TiO2-800 lowering reaction temperatures by 21 °C toluene 24 acetone mixed VOC oxidation. Characterization reveals that Pt/TiO2-800 possesses abundant oxygen vacancy clusters, enhancing TiO2-Pt electron transfer, diversifying nanoparticle sizes, stabilizing low-valent species, improving oxidative capacity. DFT calculations further underscore role modulating electronic environment defect-enhanced adsorption. This work advances Pt-TiO2 understanding offers an catalyst VOCs abatement, addressing effects systems.
