Abstract
The hydrogen evolution reaction (HER) based on electrochemical water decomposition is a promising method for producing clean and sustainable hydrogen energy. However, it is necessary to find high-activity, inexpensive, and durable non-precious metal-based electrocatalysts to realize HER. In this study, we prepared sugarcane bagasse carbon (SCBC) coated molybdenum phosphide nanocatalyst (MoP/SCBC) using a simple method and investigated the HER of the catalyst in acidic media. The MoP nanoparticles were uniformly coated on SCBC to form a unique structure, resulting in excellent electrocatalytic activity and stability of the MoP/SCBC catalyst in 0.5 M H2SO4 solution. The overpotential of the MoP/SCBC-900 catalyst was as low as 126 mV at 10 mA cm−2. The Tafel slope was 60.6 mV dec−1, and the Cdl was 18.83 mF cm−2, which outperformed most reported MoP-based HER catalysts. This study provides a more effective approach for developing high performance MoP based non-precious metal electrocatalysts derived from low-cost biomass.
