MoS2　quantum　dots　(QDs)-modified　covalent　triazine-based　framework　(MoS2/CTF)　composites　are　synthesized　through　an　in　situ　photodeposition　method.　MoS2　QDs　are　well　distributed　and　stabilized　on　the　layers　of　CTFs　by　coordination　of　the　frameworks　to　MoS2.　The　QDs–sheet　interactions　between　MoS2　and　CTFs　facilitate　interfacial　charge　transfer　and　separation.　As　a　consequence,　the　composites　exhibit　outstanding　photocatalytic　activity　and　stability　for　hydrogen　evolution　under　visible　light　irradiation　(λ≥420　nm),　that　exceed　those　over　pristine　CTFs　and　MoS2-modified　g-C3N4　(MoS2/g-C3N4)　composite,　making　them　promising　materials　for　solar　energy　conversion.　©　2018　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
