The　novel　hybrid　materials　of　ZIF-8　with　mesoporous　SBA-15　were　fabricated　through　a　facile　layer-by-layer　assembly　strategy,　and　their　catalytic　performances　for　cycloaddition　reaction　between　CO2　and　epoxide　were　also　preliminarily　explored.　The　structure　features　and　physicochemical　properties　of　the　obtained　ZIF-8/SBA-15　by　means　of　various　characterizations　demonstrated　that　SBA-15,　acting　as　a　structure-directing　agent,　could　not　only　induce　the　nucleation　of　ZIF-8　directionally　through　the　coordination　interaction　between　Zn2+　and　silanol　groups,　but　also　control　the　growth　of　the　nanocrystals　via　the　confined　space　of　mesoporous　channels.　These　results　easily　led　to　a　sharp　decrease　in　the　crystal　sizes　of　ZIF-8,　accompanied　with　extensive　exposure　of　the　active　sites.　Particularly,　the　stability　of　ZIF-8　distributed　in　the　mesopores　of　SBA-15　was　improved　significantly,　despite　their　small　size　and　low　coordination.　Therefore,　the　activity　of　the　5th　recycled　hybrid　catalysts　was　almost　twice　that　of　ZIF-8.　This　strategy　not　only　facilitates　the　preparation　of　a　high-efficiency　catalyst　for　cycloaddition　reaction,　but　also　opens　up　a　path　for　synthesis　of　other　metal-organic　frameworks　(MOFs)/silica　materials,　which　is　greatly　anticipated　for　a　wide　variety　of　applications.　[GRAPHICS]　.
