The　construction　of　photothermal　catalysts　to　provide　advanced　oxidation　ability　and　stability　is　a　great　challenge　for　eliminating　volatile　organic　compounds　(VOCs)　during　the　photothermal　catalytic　process.　Herein,　a　bimetallic　modification　method　was　proposed　to　synthesize　Pd/Fe-TiO2.　Under　ultraviolet–visible　(UV–Vis)　light　irradiation　with　the　intensity　of　610　mW/cm2,　the　optimal　0.7　wt%　Pd/0.4　wt%　Fe-TiO2　catalyst　of　which　surface　was　detected　at　the　temperature　of　165　°C　can　achieve　a　toluene　conversion　of　94　%　and　a　CO2　yield　of　87　%,　respectively.　Based　on　the　results　of　in-situ　DRIFTS,　quasi-situ　EPR,　XPS,　and　O2-TPD　tests,　it　was　found　that　two　distinct　types　of　Pd　and　Fe　active　sites　not　only　generated　reactive　oxygen　species　(ROS)　but　also　adsorbed　toluene　and　intermediate　species,　which　promoted　the　degradation　of　toluene.　It　is　proposed　that　there　be　an　electron　transfer　behavior　between　Fe　and　Pd　nanoparticles,　resulting　in　a　synergistic　interaction　of　the　two　metals.　This　study　shows　that　creating　bimetallic　modification　catalysts　is　an　efficient　method　for　eliminating　VOCs　through　photothermal　catalysis.　©　2024　Elsevier　B.V.
