Abstract
The preparation of hydrogen evolution reaction (HER) electrocatalyst with high catalytic performance is a huge challenge. In this work, we develop a MoP/Fe2P/RGO composite as a electrocatalyst for HER. The MoP/Fe2P/RGO exhibits excellent electrocatalytic performance with a Tafel slope and an onset overpotential of 51Â mV/dec and 105Â mV, respectively. To drive 10Â mA/cm2, it only requires a small over-potential of 156Â mV. The high electrocatalytic HER activity is mainly due to the synergistic effect of MoP and Fe2P. In addition, the introduction of RGO not only prevents particle aggregation and coalescence during high temperature phosphating, but also improves the conductivity of the catalyst.
