Hierarchical　SAPO-11,　featuring　both　micropore　and　mesopore　channels,　demonstrates　an　outstanding　performance　in　high-octane　gasoline　production.　In　this　work,　we　propose　an　economic　and　effective　approach　to　directly　fabricate　hierarchical　SAPO-11　molecular　sieve　from　natural　kaolin,　eliminating　the　need　for　mesoporogens.　The　systematic　characterization　results　show　that　the　kaolin-derived　SAPO-11　possesses　abundant　micro-mesoporous　structure　and　more　Br　&　oslash;nsted　(B)　acid　sites　on　the　external　surface　in　contrast　with　the　conventional　SAPO-11　prepared　employing　silica　sol　as　silicon　source　as　well　as　SAPO-11　synthesized　with　the　assist　with　of　poly(ethylene　oxide)-block-poly(propylene　oxide)-blockpoly(ethylene　oxide)　(F127).　The　analysis　of　the　formation　process　reveals　that　the　kaolin　not　only　provides　silicon　source　for　the　SAPO-11　crystal　growth,　but　also　offers　confined　environment　for　crystal　growth　along　the　preferential　orientation,　resulting　in　the　generation　of　the　microporous　and　mesoporous　structure.　Benefiting　from　these　unique　properties,　the　kaolin-derived　Pt/SAPO-11　exhibits　considerably　improved　selectivity　for　di-branched　C8　isomers　in　n-octane　hydroisomerization.　(c)　2024　The　Authors.　Publishing　services　by　Elsevier　B.V.　on　behalf　of　KeAi　Communications　Co.　Ltd.　This　is　an　open　access　article　under　the　CC　BY-NC-ND　license　(http://creativecommons.org/licenses/by-nc-nd/　4.0/).
