Abstract

Herein, we report that in situ confined growth of Pt nanoparticles (Pt NPs) on Ti₃C₂T_x MXene nanosheets (Ti₃C₂T_x NSs) affords a highly active Ti₃C₂T_x NSs/Pt NPs hybrid catalyst in a dye-sensitized system under visible light irradiation, which demonstrates ∼30 times higher H₂ evolution activity than in situ formed free Pt NPs and acheives a high apparent quantum yeild (AQY) of 5.81% at 520 nm.
