Nanostructured　covalent　carbon　nitride　(CN)　holds　great　promise　for　artificial　photosynthesis,　but　its　nanotexturation　using　templating　methods　is　restricted　by　the　weak　binding　affinities　of　neutral　silica　templates　towards　basic　precursors　that　are　kinetically　difficult　to　diffuse　into　the　nanopores　of　the　templates.　This　weak　affinity　leads　to　an　incomplete　inclusion　of　the　CN　precursors　into　the　nanostructured　silica　templates,　and　consequently,　yields　a　defective　replica　of　the　parent　porous　structures.　Here,　this　issue　is　addressed　through　the　development　of　an　innovative　synthetic　strategy　to　facilitate　the　sufficient　inclusion　of　CN　precursors　in　silica　templates,　by　taking　advantage　of　the　surface　acidification　of　silica　and　sonication-promoted　insertion.　The　ordered　mesoporous　CN　(ompg-CN)　fabricated　using　SBA-15　mesozeolite　as　the　template　has　been　demonstrated　to　show　a　better　2D　mesoporous　hexagonal　framework,　larger　surface　area,　and　higher　photocatalytic　activity　than　that　synthesized　by　the　traditional　method.　This　innovative　strategy　can　in　general　be　expanded　to　other　silica　templates　with　various　nanostructures,　enabling　the　creation　of　stable　polymeric　CN　nanostructures　with　maximized　material　and　structure　functions.　Based　on　a　combination　of　surface　acidification　and　sonication-promoted　insertion,　an　optimized　and　general　synthetic　strategy　is　established　for　the　templated　construction　of　polymeric　carbon　nitride　nanoarchitectures　with　maximized　material　and　structure　functions.　Copyright　©　2013　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
