Single platinum atoms immobilized on an MXene as an efficient catalyst for the hydrogen evolution reaction

Surface Modified MXene‐Based Nanocomposites for Electrochemical Energy Conversion and Storage

“…Other than the oversaturation, in Wang and the co‐workers' work, the modification process was driven by the applied potential. During the reaction, electrochemical exfoliation of Mo 2 TiC 2 T m and simultaneous Pt atom immobilization at Mo vacancy sites were realized ( Figure ) . Through the strategy, the bottom‐up process was stopped at the nuclear step, configuring a heteroatom modified MXene with a smooth surface in atomic level.…”

“…Instead of the heterostructure, recently a heteroatom (Pt) modified Mo 2 TiC 2 T m MXene with a smooth surface in atomic level was designed for HER application . As shown in Figure , the Mo 2 TiC 2 T m ‐Pt SA catalyst presented an extraordinary catalytic ability with a low overpotential of 30 mV to achieve the current density of 10 mA cm −2 in 0.5 m H 2 SO 4 , which was significantly lower than the pristine Mo 2 TiC 2 T m (around 300 mV) and even lower than the commercial Pt/C catalyst.…”
