Description
Technical Field
The invention belongs to the field of functional material synthesis, and particularly relates to a preparation method of a three-dimensional nano porous iron phosphide cube.
Background
The reduction of fossil fuels and the exacerbation of environmental crisis have attracted public attention over the last several decades. To solve these problems, the development and utilization of renewable energy have been imminent, and hydrogen energy becomes a very promising renewable energy source because of its high energy storage density and zero carbon emission. Electrochemical water splitting currently provides an efficient method for large-scale production of high-purity hydrogen, but requires an efficient and stable electrocatalyst to reduce the overpotential of the hydrogen evolution reaction. Currently, noble metals Pt, Ru and Pd are the most excellent electrocatalysts for hydrogen evolution reaction (angelw. chem. int. ed.2013,125,3192), but their wide application is severely limited by their low content and high cost in nature. For this reason, rational development of effective noble metal-free HER catalysts is of great importance for large-scale commercialization.
Transition metal phosphide materials can provide high current density at low overpotentials and faster reaction kinetics in hydrogen evolution reactions due to having phosphorus and metal as proton acceptor and hydride acceptor sites (j.am. chem. soc.2013,135, 9267). Meanwhile, iron is one of the most abundant (about 5% of the earth's crust) metals on earth, and is at least 2 orders of magnitude cheaper than the same class of transition metals (such as nickel and cobalt), which is beneficial for commercial mass production. In addition, the iron phosphide material with the three-dimensional porous nanostructure is designed and synthesized, so that the specific surface area of charge transfer is increased, and the efficiency of hydrogen evolution reaction is improved. Therefore, the development of the iron phosphide material with the porous structure has very important theoretical significance and practical value for the hydrogen evolution reaction.
