Abstract

Herein, we report that in situ confined growth of Pt nanoparticles (Pt NPs) on Ti3C2Tx MXene nanosheets (Ti3C2Tx NSs) affords a highly active Ti3C2Tx 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.
