The　common　strategy　for　the　design　of　photocatalytic　materials　is　to　load　small-sized　cocatalysts　onto　large-sized　photocatalysts　for　efficient　charge　separation.　In　this　study,　a　new　design　strategy　is　presented　to　anchor　smallsized　TiO2　photocatalysts　onto　large-sized　Ti3C2-Mxene　cocatalysts,　which　can　provide　enriched　active　sites　to　receive　photo-generated　electrons,　thus　achieving　fast　charge　separation.　Based　on　this　strategy,　the　4h-hydrogen　production　rate　of　the　optimized　photocatalytic　system　(62.5　mu　mol)　is　15.2　times　higher　than　that　of　pure　TiO2　(4.1　mu　mol),　strongly　demonstrating　the　feasibility　of　our　design　strategy.　The　strategy　here　presents　an　effective　way　to　design　novel　photocatalytic　systems　with　superior　photocatalytic　properties.
