“…Besides bimetallic TMPs, trimetallic TMPs can display better electrocatalytic performance by multiple synergistic effects between metal cations. For instance, Liu's group prepared a series of TMPs containing different metal components (M = Fe, Co, Ni) . The OER activities of these catalysts followed the order of FeCoNiP>CoNiP>FeNiP>FeCoP>NiP>CoP>FeP (Figure h), manifesting that multiple cations doping was a feasible way to significantly improve the OER performance.…”

The exploitation of cheap and efficient electrocatalysts is the key to make energy‐related electrocatalytic techniques commercially viable. In recent years, transition metal phosphides (TMPs) electrocatalysts have gained a great deal of attention owing to their multifunctional active sites, tunable structure, and composition, as well as unique physicochemical properties. This review summarizes the up‐to‐date progress on TMPs in energy‐related electrocatalysis from diversified synthetic methods, ingenious‐modulated strategies, and novel applications. In order to set forth theory–structure–performance relationships upon TMPs, the corresponding reaction mechanisms, electrocatalytsts' structure/composition designs and desired electrochemical performance are jointly discussed, along with demonstrating their practical electrocatalytic applications in overall water splitting, metal–air batteries, lithium–sulfur batteries, etc. In the end, some underpinning issues and research orientations of TMPs toward efficient energy‐related electrocatalysis are briefly proposed.

“…Numerous efforts have been devoted to develop low cost and highly efficient OER electrocatalysts, including transition metal nitrides,, phosphides, phosphates, oxides,, hydroxides,, oxyhydroxides,, and dichalcogenides . Among these transition metal compound electrocatalysts, nickel sulfides (Ni 3 S 2 , NiS 2 , α‐NiS, and β‐NiS) are considered among the most promising candidates as OER electrocatalysts for water electrolysis in alkaline media because of their good catalytic activity and natural abundance …”

Efficient Electrocatalytic Oxygen Evolution at Extremely High Current Density over 3D Ultrasmall Zero‐Valent Iron‐Coupled Nickel Sulfide Nanosheets

Nonprecious water oxidation electrocatalysts that perform well at high current densities are among the key enabling drivers of renewable energy technologies. Herein, we report a novel strategy to produce 3D ultrasmall zero‐valent iron‐coupled nickel sulfides nanosheets (Fe0−NixSy) hybrid on self‐supported conductive Ni foam (denoted as Fe0−NixSy/NF) through a robust single‐step gas–solid reaction. In this 3D hybrid, the Fe0−NixSy nanosheets with a length of approximately 400 nm and an average thickness of 33 nm are uniformly grown on the Ni foam. Benefiting from the unique 3D hierarchical structure and synergistic effect between Fe0 and NixSy, the 3D Fe0−NixSy/NF hybrid shows an excellent electrocatalytic activity towards oxygen evolution reaction (OER) at extremely high current densities in basic media. The current densities of 1000 and 1500 mA cm−2 are achieved at low potentials of 1.57 and 1.60 V, respectively, thus meeting the expected OER standards for industrial applications. These overpotentials of the 3D Fe0−NixSy/NF hybrid are the lowest among all previously reported nickel‐sulfide‐based electrocatalysts, and are even superior compared to state‐of‐the‐art Ir/C catalysts. We further demonstrate that the integration of the 3D Fe0−NixSy/NF electrocatalyst as both anode and cathode with a silicon photovoltaic cell enables highly active and sustainable solar‐driven overall water splitting.

The development of cheap, high‐efficiency, and long‐term durable oxygen evolution reaction (OER) electrocatalysts has become a research hotspot. Carbon‐confined transition‐metal phosphides derived from coordination polymers and metal–organic frameworks have received great attention. Herein, a CoP/N‐doped carbon‐400 (CoP/NC‐400) nanowire is prepared using a coordination polymer [Co(C4H7NO4)]·xH2O (Co‐Asp, Asp = l‐aspartic acid) nanowire as the precursor and template through simultaneous pyrolysis and low‐temperature phosphidation. Electrochemical tests indicate that the CoP/NC‐400 nanowire displays better OER properties than CoP/NC‐300/500 nanowires. The overpotential required to reach a current density of 10 mA cm−2 is 320 mV with a minimum Tafel slope of 89 mV dec−1. Moreover, at a higher current density, the OER performance of the CoP/NC‐400 nanowire is superior to that of RuO2. The excellent electrochemical performance of the CoP/NC‐400 nanowire is attributed to the high electrochemical surface area and the strong synergistic effect of the CoP nanoparticle and the N‐doped carbon nanowire.
