Abstract
In recent years, transition metal phosphides as electrocatalysts are the research hotspot due to their low cost and high electrical conductivity. However, their applications are largely restricted by their low conversion efficiency and sluggish reaction kinetics. Herein, we report several kinds of flower-like Co0.4Fe1.6P catalysts through a facile hydrothermal approach and subsequent phosphating process. The as-prepared materials possess sufficient catalytic sites to facilitate ion transfer. The Co0.4Fe1.6P-2 electrode presents an overpotential of 244 mV@50 mA cm–2 for oxygen evolution reaction (OER) and 96 mV@10 mA cm–2 for hydrogen evolution reaction (HER). Moreover, the assembled two-electrode system presents a voltage of 1.66 V at the current density of 50 mA cm–2.
期刊介绍：
Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
