Abstract
The development of highly effective and non-precious electrocatalysts for the hydrogen evolution reaction (HER) remains highly desirable. In this work, we report a facile strategy using preoxidized fiber films as a precursor to prepare a flower-like Mo2C-based electrocatalyst for the HER, in which the pyrolysis of a mixture of urea and ammonium molybdate tetrahydrate during thermal treatment realized nitrogen doping. The N–Mo2C/CNFs-900 electrocatalyst exhibits excellent HER activity with a small overpotential of 119 mV at 10 mA cm−2 in an alkaline solution and the Tafel slope was calculated to be 106.9 mV dec−1. N-M-9 demonstrated long term stability over 24 h. With an increase in temperature, MoO2 was gradually transformed into Mo2C and the formation of Mo2C was promoted upon nitrogen doping. This work provides a feasible approach to synthesize high performance HER electrocatalysts for renewable energy applications.
