Abstract：

The　control　of　volatile　organic　compounds　(VOCs)　from　cooking　oil　fumes　via　synergic　photothermocatalytic　oxidation　not　only　saves　energy,　but　also　helps　to　reduce　carbon　emissions.　Differences　between　the　copper　oxide−ceria　(CC)　supported　atomically-dispersed　(Pt1/CC)　and　particulate　Pt　(PtNPs/CC)　on　photothermocatalytic　heptane　oxidation　were　investigated.　The　conversion　efficiency　at　170　oC　of　heptane　oxidation　over　the　Pt1/CC　catalyst　was　55%　higher　than　that　over　the　PtNPs/CC　catalyst.　PtNPs/CC　showed　a　larger　capacity　of　heptane　adsorption,　but　limited　amounts　of　the　adsorbed　oxygen　and　active　surface　lattice　oxygen　species　were　difficult　to　completely　oxidize　the　over-adsorbed　heptane.　Heptane　and　its　intermediates　gradually　accumulated　at　the　active　sites,　resulting　in　poor　catalytic　activity　and　stability.　However,　Pt1/CC　possessed　a　strong　electron　donating　ability　due　to　its　unique　coordination　unsaturated　sites　and　electron　structure,　which　was　conducive　to　oxygen　activation.　This　allowed　rapid　conversion　of　heptane　and　intermediates,　accelerating　oxidation　of　the　adsorbed　heptane　to　CO2　and　H2O.　The　complete　oxidation　of　500　ppm　heptane　was　basically　achieved　at　190　oC　and　an　optical　power　density　of　300　mW/cm2.　©　2023　Elsevier　B.V.
