Photocatalytic　hydrogen　production　holds　great　promise　for　alleviating　the　energy　shortage　through　effective　photo-to-chemical　conversion,　and　the　development　of　visible-light　responsive,　low-cost　and　sustainable　photocatalysts　remains　key　priority.　In　this　study,　carbon　quantum　dots/covalent　triazine-based　framework　(CQDs/CTF)　non-metallic　photocatalyst　was　constructed　through　a　simple　impregnation　method　for　photocatalytic　H2　evolution.　Upon　0.24%　CQDs　loading,　a　three-fold　enhanced　H2　production　activity　of　102　μmolg−1h−1　was　achieved　compared　with　pristine　CTF-1　(34.5　μmolg−1h−1).　Photoluminescence　and　photoelectrochemical　study　revealed　carbon　quantum　dots　served　as　the　electron　libraries,　which　was　conducive　to　facilitate　electron　capture　and　promote　the　separation　of　photoinduced　electron-hole　pairs　in　CTF-1.　Notably,　the　excitation-independent　up-conversion　fluorescent　characteristics　of　CQDs　endowed　the　catalysts　broadened　visible-light　response　range　and　higher　solar　energy　utilization　efficiency.　This　study　deepens　insights　into　the　mechanism　of　CQDs　modification　and　paves　a　trustworthy　strategy　for　harvesting　visible-light-driven　metal-free　photocatalyst　with　highly-active　and　robust　performance.　©　2022　Hydrogen　Energy　Publications　LLC
