“…The OER performance of MnP x @ MoP y /N,P‐Gr hybrid is credited to its mesoporous structure, multiple electroactive sites and synergistic effect of MnP x and MoP y . In another study, a hybrid of CoP(MoP) and CoMoO 3 coated with N‐doped carbon shell (CoP(MoP)‐CoMoO 3 @CN) was synthesized as OER electrocatalyst through thermal decomposition and phosphidation approach . The electronegative P atoms on the CoP(MoP)‐CoMoO 3 @ CN and the synergistic effect of hybrid promoted the deprotonation process a nd p eroxide formation during the water oxidation reaction and the refore reduced the overpotential for oxygen generation.…”

The sustainable and scalable production of hydrogen through hydrogen evolution reaction (HER) and oxygen through oxygen evolution reaction (OER) in water splitting demands efficient and robust electrocatalysts. Currently, state‐of‐the‐art electrocatalysts of Pt and IrO2/RuO2 exhibit the benchmark catalytic activity toward HER and OER, respectively. However, expanding their practical application is hindered by their exorbitant price and scarcity. Therefore, the development of alternative effective electrocatalysts for water splitting is crucial. In the last few decades, substantial effort has been devoted to the development of alternative HER/OER and water splitting catalysts based on various transition metals (including Fe, Co, Ni, Mo, and atomic Pt) which show promising catalytic activities and durability. In this review, after a brief introduction and basic mechanism of HER/OER, the authors systematically discuss the recent progress in design, synthesis, and application of single atom and cluster‐based HER/OER and water splitting catalysts. Moreover, the crucial factors that can tune the activity of catalysts toward HER/OER and water splitting such as morphology, crystal defects, hybridization of metals with nonmetals, heteroatom doping, alloying, and formation of metals inside graphitic layered materials are discussed. Finally, the existing challenges and future perspectives for improving the performance of electrocatalysts for water splitting are addressed.

“…[ 76 ] To this end, the Co‐Fe‐P nanotubes ( Figure a) presented excellent catalytic performance as well as exhibited a high structural stability during the long‐term measurements. [ 77 ] Besides, the 1D‐nanostructured Ni‐Co‐P CNTs, [ 78 ] Ni‐Co‐P nanoneedles, [ 79 ] Co‐Mo‐P nanowires have been reported, [ 80 ] all of which enabled a high activity and good stability for both HER and OER, making them potential candidates for water splitting applications. ii) 2D materials have more of their surface atoms exposed, which can be ascribed to their large lateral size and ultrathin thickness, making them particularly attractive for electrocatalysis.…”

their efficiencies, the catalysts employed are basically required to overcome the high energy barriers and sluggish kinetics of the electrochemical HER, OER, and ORR. [3] The benchmarking catalysts for ORR and HER are platinum (Pt)-based noble metal catalysts, whereas iridium (Ir) and ruthenium (Ru) oxides are highly active toward the OER. [4] Nevertheless, the high cost and scarcity of these precious metal-based catalysts have notably hindered their wide applications and commercialization. [5] Therefore, developing highly active, low cost, and sustained catalysts for these key electrocatalytic processes is paramount and apparently rewarding for the sustainable and large-scale implementation of clean energy devices. [6] To reduce, and hopefully to eliminate the usage of these precious metal-based catalysts, there have been intensive researches, in order to develop the practically and economically viable alternative electrocatalysts. [7] In this connection, phosphorus (P) is one of the most earth-abundant elements, thereby P-based materials have been considered being employed for electrocatalysis. [8] Indeed, P-based inorganic materials, especially the black phosphorus, metal phosphides, and metal phosphates, have attracted immense attention recently as a class of promising electrocatalysts, and presented intrinsic electrochemical activity and widely tunable properties. [9] Black phosphorus (BP) is a layer-structured semiconductor, in which individual atomic layers are stacked and held together by van der Waals interactions. [10,11] Until recently, BP stands out as a group of promising catalysts that have been investigated and shown to exhibit catalytic activities, owing to their unique puckered layer-structure, tunable band gap, and high carrier mobility. [12,13] As suggested by recent researches, 2D catalysts with reduced layer numbers or the thickness can present increased surface area and hence expose additional active sites, in comparison with their bulk counterparts. [14] To this end, phosphorene, as the building block for BP, possesses a monolayer (or a few layer) sheet structure, and has been explored for electrocatalysis and expected to promote the catalytic efficiency. [15,16] Nevertheless, because of the densely packed lone-pair p-electrons of phosphorus atoms, it would be hard for phosphorene to adsorb hydrogen, leading to the large hydrogen adsorption energy, and thus poor HER electrocatalytic Enormous progresses have been made in developing advanced energy conversion and storage technologies, which inevitably require high-performance electrocatalysts. Recently, phosphorus (P)-based materials have drawn tremendous attention as a class of promising electrocatalysts and presented intrinsic electrochemical activity and widely tunable property. In a timely response to the ongoing interests, issues faced in P-based inorganic materials, and the approaches to address them in relation to energy conversion reactions, including hydrogen evolution reaction, oxygen evolution reaction, and oxygen reduction reactio...
