Electrochemical water splitting is widely regarded as a feasible industrial h
ydrogen production technology that can efficiently convert water into hy
drogen gas. The electrolysis of water can be divided into the hydrogen ev
olution reaction (HER) at the cathode and the oxygen evolution reaction
(OER) at the anode, both of which require a certain overpotential to proce
ed. In industrial applications, the commonly used electrode material for H
ER is platinum (Pt), while the OER electrode often uses precious metal oxi
des such as iridium dioxide (IrO2) and ruthenium dioxide (RuO2). Due to t
he limited reserves and high cost of precious metals, it is challenging for t
hem to support large-scale and low-cost industrial hydrogen production.
Therefore, the development of efficient, long-life, and non-precious metal
(non-platinum) dual-function (applicable to both HER and OER) electrocat
alysts has become an important research topic. Among candidate materia
ls, Ni/Co bimetallic phosphides with outstanding electrolytic properties h
ave received wide attention in this regard. Furthermore, metal-organic fra
meworks (MOFs) composed of transition metals and organic linkers exhibi
t high specific surface area, mechanical strength, controllable active sites,
and multi-scale pore structures. They have great potential in electrocataly
st applications. This technology utilizes an in-situ growth method to grow
Ni/Co bimetallic MOFs on Ni foam substrates and then undergo phosphor
ization treatment to prepare efficient dual-function electrocatalysts for wa
ter splitting. This technique not only has low cost but also improves the el
ectronic conductivity between the electrode and electrolyte, while simulta
neously enhancing the mechanical strength required for gas bubble gener
ation during water decomposition. Our team has also established a large-
area alkaline anion exchange membrane water electrolyzer to evaluate the
feasibility of meeting industrial hydrogen production demands with
