Developing　efficient　and　reusable　catalysts　to　transform　raw　feedstocks　into　high　value-added　fine　chemicals　and　biofuels　has　received　considerable　research　interest.　Herein,　we　report　ordered　mesoporous　carbon　(OMC)　encapsulating　KF　to　design　novel　chainmail　solid　base　catalysts　(KF@OMC-x,　where　x　stands　for　the　weight　ratio　of　potassium).　The　OMC　armor　can　be　facilely　prepared　from　a　one-step　mechanochemical　synthesis　without　the　assistance　of　any　solvents,　which　was　achieved　from　the　grinding　of　resorcinol,　terephthalaldehyde,　and　block　copolymer　template　(Pluronic　F127,　PEO106-PPO70-PEO106),　solidothermal　treatment　at　150　degrees　C,　and　calcined　at　360　degrees　C　for　the　removal　of　the　template.　The　obtained　OMC　was　then　impregnated　with　the　KF　precursor　and　annealed　at　500　degrees　C　to　reinforce　the　interaction,　and　the　KF　superbase　site　can　be　encapsulated　into　the　OMC　armor.　The　resultant　KF@OMC-x　possess　characteristics　including　large　BET　surface　areas　(351-445　m(2)/g),　long-range　ordered　mesoporosity　with　narrow　pore　sizes　(similar　to　6.0　nm),　and　good　dispersion　of　KF　superbase　sites　with　an　enhanced　stability.　Consequently,　KF@OMC-x　can　be　employed　as　high-efficient　and　reusable　catalysts　in　base-catalyzed　liquid　reactions　including　toward　transesterification　to　biodiesel　and　Knoevenagel　condensation　to　fine　chemicals.　Their　activities　were　even　better　than　widely　used　strong　base　catalysts　such　as　KF,　Na2CO3,　CaO,　and　hydrotalcite.　This　study　may　help　to　develop　effective　and　stable　solid　base　catalysts　for　the　scalable　production　of　biofuels　under　harsh　industrial　processes.
