NiCoP/Mo ₃ Se ₄ Nano‐Heterojunction as a Promising Bifunctional Catalyst for Full‐Water Splitting under Low Cell Voltage

The simultaneous manipulation of the catalytic activity and intrinsic electrical conductivity in a unified system is difficult yet meaningful to unravel the possible strategy that can enhance the water splitting performance. In this work, a low cost and highly effecient NiCoP/Mo 3 Se 4 nano-heterogeneous bifunctional catalyst was reported for full water splitting. Further analysis revealed the abundance interfaces in NiCoP/Mo 3 Se 4 play great role in optimizing the electronic structure of the nanoheterogeneous to efficient charge transfer. As expected, low voltage of 1.90 V was needed to drive full water splitting at high current density of 400 mA cm -2 .
