Fuels　with　extremely　low　sulfur　content　are　highly　desirable　as　a　result　of　the　growing　environmental　concerns.　In　this　work,　a　simple　and　novel　method　to　connect　a　Zr-IV　open　site　with　polyoxometalates　(POM)　was　introduced,　which　was　used　as　an　effective　heterogeneous　catalyst　for　oxidative　desulfurization　of　fuel　oil.　ZrPTA(X)-BTC　composites　were　synthesized　conveniently　and　rapidly　at　room　temperature　and　atmospheric　pressure　using　pyromellitic　acid　(BTC)　as　a　linker.　The　products　were　characterized　by　XRD,　TGA,　FT-IR,　NMR,　SEM,　and　N　2　adsorption-desorption,　which　verified　the　successful　preparation　of　ZrPTA(X)-BTC　composite.　ZrPTA(X)-BTC　catalyst　has　high　content　of　active　components,　and　has　excellent　catalytic　activity　in　oxidative　desulfurization　reaction.　It　achieves　rapid　and　complete　desulfurization　under　mild　reaction　conditions　(T　=　50　degrees　C,　O/S　=　4,　t　=　30　min,　DBT　removal　rate　reaches　100%).　Further　studies　show　that　the　synergistic　catalysis　of　a　Zr-IV　open　site　and　PTA　molecule　is　the　reason　for　its　high　catalytic　activity,　in　which　the　Zr-IV　open　site　promotes　the　decomposition　of　H2O2　into　Of,　PTA　molecules　combine　with　O-2　center　dot　to　form　peroxytungstate　(W(O-2)(n)),　and　the　close　distance　between　the　Zr-IV　open　site　and　PTA　in　ZrPTA(X)-BTC　allows　H2O2　to　be　efficiently　utilized.　In　addition,　ZrPTA(X)-BTC　can　be　easily　recovered　and　reused　for　at　least　five　times,　and　only　a　slight　decrease　in　catalytic　activity　has　occurred.　Therefore,　ZrPTA(X)-BTC　has　high　catalytic　activity,　high　stability,　and　good　reusability,　which　is　a　potential　catalyst　that　can　realize　the　application　of　fuel　ultradeep　desulfurization.
