“…The catalyst shows high efficiency in both HER and OER as well as in the TWS by keeping Ni 2 P@NSG as both anode and cathode shows the overall cell voltage as 1.57 V at 10 mA cm −2 [63] . The strong interaction of 0D Ni 2 P and the 2D NSG changes the electronic configuration via transferring electron from Ni 2 P. Also, the binding energy change on the intermediate formed with the Ni 2 P@NSG and the heteroatom doping further alters the adsorption energy of the intermediated in the process of OER and HER [9,59] . The detail of the studies with various nickel phosphides describes the efficiency and durability of the catalyst for TWS application [63] .…”

“…The phosphorous‐phosphorous bonding presence in TMPs was usually less stable which makes the OER/HER process in a facile manner. By way of introducing, the tremendously active Co and Ni based phosphides, have been studied for total water splitting which showed considerable activity and stability [58–61] .

Producing pure hydrogen (H2) is presumably an alternative way for replacing the fossil fuels. Since the last few decades finding alternatives for state‐of‐the‐art catalysts such as IrO2 and RuO2 for oxygen evolution reaction (OER) and platinum for hydrogen evolution reaction (HER) has been a major challenge in the field of water electrolysis. To replace such precious metals, many efforts have been made to develop transition metal based bifunctional catalyst for alkaline water electrolysis. Among them, transition metal phosphides (TMPs) show superior activity in both OER and HER with varying pH conditions. Moreover, the different phases of phosphides, P‐rich or P deficient metal composites (Ni/Co−P) offer a great opportunity in total water splitting (TWS) applications. There is no detailed review in the literature outlining the possible combinations, synthesis methods and morphologies of Ni and Co based phosphides. Based on the above shortage about TMPs as a bi‐functional catalyst for water electrolysis, this review summarizes the activity and stability Ni and Co phosphides. Furthermore, the review highlights monometallic phosphides such as NiP and CoP, bi‐metallic phosphides such as NiCoP, and the synergistic effect of doping Fe into NiP/CoP or Fe ‐NiCoP systems while detailing their preparation methods. Overall, this review extends the role of designing Ni and Co phosphides for efficient large scale electrocatalysis of hydrogen production.

“…High abundance of non‐precious catalysts based on transition metals including Ni, Co, Mo, and W have been investigated widely and regarded as promising candidates in replacing Pt based materials [10–13] . Among them, transition‐metal phosphides, especially nickel and cobalt phosphides, are reckoned the most effective replacement to Pt [12,14–17] . Relevant research initiated in 2005 by Rodriguez's group, where density functional theory (DFT) is employed to investigate the behavior of a series of catalysts for HER [18] .…”

Developing non‐precious metal catalysts towards hydrogen evolution reaction (HER) is of both high scientific and technical importance for the widespread application of water electrolysis. Herein, Ni2P nanoparticles coated with a ultrathin N‐doped carbon shell were prepared as a highly efficient HER catalyst. Ni2P@CN exhibits both enhanced catalytic activity and durability in comparison with the carbon‐supported Ni2P counterpart, and represents 100% faradaic yield for HER in an acidic medium. The improved charge transfer of N‐doped graphitic carbon shells contributes to the increase in activity. Meanwhile, the carbon shells suppress the aggregation and exfoliation of Ni2P nanoparticles. As a result, the synergistic role of the N‐doped carbon layer confers the Ni2P cores with boosted activity and stability.

Developing efficient and inexpensive electrocatalysts for the hydrogen evolution reaction (HER) is critical to the commercial viability of electrochemical clean energy technologies. Transition metal phosphides (TMPs), with the merits of abundant reserves, unique structure, tunable composition, and high electronic conductivity, are recognized as attractive HER catalytic materials. Nevertheless, the HER electrocatalytic activity of TMPs is still limited by various thorough issues and inherent performance bottlenecks. In this review, these issues are carefully sorted, and the corresponding reasonable explanations and solutions are elucidated on the basis of the HER catalytic activity origins of TMPs. Subsequently, highly targeted multiscale strategies to improve the HER performance of TMPs are comprehensively presented. Additionally, critical scientific issues for constructing high‐efficiency TMP‐based electrocatalysts are proposed. Finally, the HER reaction process, catalytic mechanism research, TMP‐based catalyst construction, and their application expansion are mentioned as challenges and future directions for this research field. Expectedly, this review offers professional and targeted guidelines for the rational design and practical application of TMP‐based HER catalysts.
