Abstract：

Due　to　the　capacity　to　offer　abundant　catalytic　sites　within　porous　solids　featuring　high　surface　areas,　metal-organic　frameworks　(MOFs)　and　their　derivatives　have　garnered　considerable　attention　as　prospective　catalysts　in　environmental　catalysis.　To　promote　the　industrial　application　of　MOFs,　there　is　an　urgent　need　for　an　effective　and　environmental-friendly　preparation　approach.　Breaking　through　the　limitation　of　the　traditional　two-step　preparation　method　that　Pd　was　introduced　to　the　already　prepared　Ce-BTC　(Pd/Ce-BTC,　BTC　=　1,　3,　5　benzenetricarboxylate),　in　this　work,　we　present　a　novel　one-pot　solvothermal　method　for　synthesizing　the　Pd　material　supported　by　Ce-BTC　(Pd@Ce-BTC).　After　pyrolysis　in　N2　flow　or　air　flow,　Pd-CeO2　catalysts　derived　from　Pd@Ce-BTC　exhibited　much　higher　CO　oxidation　activity　than　those　from　Pd/Ce-BTC.　Moreover,　Pd/Ce-BTC　and　Pd@Ce-BTC　pyrolyzed　in　N2　flow　(Pd/Ce-BTC-N　and　Pd@Ce-BTC-N)　could　better　catalyze　the　oxidation　of　CO　than　Pd/Ce-BTC　and　Pd@Ce-BTC　pyrolyzed　in　air　flow　(Pd/Ce-BTC-A　and　Pd@Ce-BTC-A).　Further　characterizations　revealed　that　the　abundant　surface　Ce3+　species,　rich　surface　adsorbed　oxygen　species　and　superior　redox　properties　were　the　main　reasons　for　the　superior　CO　oxidation　activity　of　Pd@Ce-BTC-N.　©　2024　Elsevier　B.V.
