Photocatalytic　CO2　reduction　provides　a　promising　way　for　solving　the　energy　crisis　and　environmental　issues.　Herein,　a　well-integrated　photocatalyst　is　fabricated　through　growing　leaf-like　zeolitic　imidazolate　frameworks　(ZIF-L)　on　branch-like　titanium　dioxide/carbon　(TiO2/C)　nanofiber　for　selective　CO2　reduction.　This　platform　enables　the　study　of　the　synergistic　effect　of　the　photocatalytic　performance,　where　the　strong　CO2　adsorption/activation,　highly　efficient　light-harvesting,　promoted　electron-hole　pairs　separation,　and　specific　metal　Lewis　sites　are　met　by　integrating　suitable　band　matched　ZIF　and　TiO2,　as　well　as　interfaced　graphitic　carbon.　As　a　result,　a　largely　increased　CO　generation　rate　of　28.6　mu　mol　h(-1)　g(-1)　with　remarkable　selectivity　of　99　%　is　achieved　in　the　TiO2/C@ZnCo-ZIF-L　without　using　sacrificial　reagent.　This　work　thus　provides　an　insight　into　the　rational　construction　of　well-integrated　composites　to　enhance　photocatalytic　performance　via　a　well-balanced　synergistic　effect.
