Through　the　method　of　solvent-free　confined　encapsulation,　,　dibromo-p-diphenyl-　p-diphenyl　and　4,4　＇-bipyridine　,　4　＇-bipyridine　were　adsorbed　into　the　UiO-67-67　material,　,　and　then　in　situ　polymerized　into　the　polymer　ionic　liquid　PBpy-Br.-Br.　The　composite　PBpy-Br@UiO-67-Br@UiO-67　contains　three　kinds　of　active　centers:　:　Br-,　-　,　Zr-OH/Zr-OH2-OH/Zr-OH2　and　N　heterocyclic.　The　structure　was　characterized　by　X-ray-ray　diffraction(XRD),　(　XRD　),　Fourier　transform　infrared(FTIR)　(　FTIR　)　spectroscopy,　,　scanning　electron　microscopy(SEM),　(　SEM　),　13　C　nuclear　magnetic　resonance　spectrometry(13C　(　13　C　NMR),　),　Brunauer-Emmett-Teller(BET)-Emmett-Teller　(　BET　)　analysis　and　thermogravimetric　analysis(TGA).　(　TGA　)　.　The　composite　was　applied　to　catalyze　the　cycloaddition　reaction　of　CO2　and　epichlorohydrin.　On　the　basis　of　single　factor　experiments,　,　the　optimal　reaction　conditions　determined　by　response　surface　optimization　were　100　degrees　C,　,　p　CO2　=0.1　MPa,　,　PBpy-Br@UiO-67-Br@UiO-67　mass　fraction　of　0.22%　and　22　h.　Under　the　optimum　reaction　conditions,　,　the　yield　of　cyclochlorocarbonate　reached　99.6%,　,　and　the　conversion　decreased　by　only　2.3%　after　5　cycles.　When　the　composite　was　used　to　catalyze　other　epoxides,　,　a　conversion　of　over　50%　was　obtained.　PBpy-Br@UiO-67-Br@UiO-67　has　milder　reaction　conditions　and　higher　catalytic　efficiency,　,　which　provides　a　new　catalytic　system　for　CO2　2　fixation　and　conversion.
