Abstract：

Volatile　Organic　Compounds　(VOCs)　are　omnipresent　in　the　sphere　of　human　industrial,　harboring　latent　adverse　consequences　for　health　and　the　ecological　system.　The　photothermal　catalytic　oxidation　of　VOCs　is　an　advanced　integrated　technology　that　harnesses　the　combined　effects　of　light　and　heat　energy　to　enhance　the　efficiency　of　VOCs　degradation.　Herein,　a　bimetallic　Metal-Organic　Framework　(MOF)　was　synthesized　with　the　incorporation　of　Ce　into　the　UiO-66-NH2(Zr)　(i.e.,　UNH(Zr)),　UiO-66-NH2(Zr2Ce)　(i.e.,　UNH(Z2C)),　which　was　achieved　with　Ce　atom　substituting　for　a　portion　of　Zr　atom　within　the　Zr-oxo　clusters.　Pt　nanoparticles　(NPs)　are　integrated　with　MOFs　to　form　composites　using　the　dual-solvent　method.　Ce-oxo　fulfills　a　bifunctional　role:　it　not　only　facilitates　the　enhancement　of　the　ligand-to-metal　charge　transfer　(LMCT),　but　also　establishes　interaction　with　Pt　NPs.　Ce-oxo　mediates　an　enhancement　of　electron　density　on　Pt　NPs.　This　phenomenon　enhances　the　adsorption　and　activation　of　oxygen,　significantly　boosting　the　photocatalytic　performance　for　toluene　degradation,　as　demonstrated　by　a　reduction　of　30　℃　for　complete　mineralization　of　toluene　as　compared　to　that　of　Pt@UiO-66-NH2(Zr)　(i.e.,　PUNH(Zr)).　This　study　potentially　offers　new　insights　into　the　relationship　between　electron　transfer　effects　in　bimetallic　MOF-based　catalysts　and　their　efficient　catalytic　performance　for　VOCs　degradation.　©　2024　Elsevier　B.V.
