Hydrogen　energy,　as　an　ideal　renewable　resource　and　green　energy　replacement,　has　attracted　growing　attention.　However,　constructing　highly　active　and　stable　catalysts　for　hydrogen　evolution　from　Formic　acid　(FA)　is　still　a　challenging　issue　for　development　of　renewable　hydrogen　energy.　Herein,　we　develop　a　facile　defect　engineering　strategy　to　construct　N-deficient　ordered　mesoporous　graphitic　carbon　nitride　coupled　with　AgPd　nanoparticles　(denoted　as　AgPd/N-ompg-C3N4).　Impressively,　the　as-prepared　Ag0.1Pd0.9/N-ompg-C3N4　catalyst　exhibits　remarkable　activity　with　the　Turnover　frequency　(TOF)　value　of　1588.2　h−1　and　robust　stability　with　only　a　slight　decrease　in　activity　after　ten　cycles.　Such　markedly　enhanced　catalytic　performance　of　Ag0.1Pd0.9/N-ompg-C3N4　is　mainly　attributed　to　the　unique　structure　of　N-ompg-C3N4　with　higher　surface　area　and　abundant　surface　defects,　the　strong　metal　−　support　interaction　between　AgPd　and　N-ompg-C3N4,　and　charge　transfer　from　Pd　to　Ag.　This　study　provides　a　novel　and　efficient　strategy　for　designing　efficient　catalysts　to　drive　the　hydrogen　evolution　from　FA.　©　2021
