A review of typical transition metal phosphides electrocatalysts for hydrogen evolution reaction

Interfacial Engineering of MoS2@CoS2 Heterostructure Electrocatalysts for Effective pH-Universal Hydrogen Evolution Reaction

“…Compared with other alternatives, both CoS 2 and MoS 2 have sulfur, which constitutes a higher heterojunction matching degree. Moreover, CoS 2 can improve the electrical conductivity of MoS 2 and the catalytic capacity as a second phase. ,, Generally, HER performance in alkaline and neutral conditions lags that in acidic conditions because of the slow rate at which water molecules dissociate. , Consequently, the advancement of electrode materials for HER demonstrating superior performance across the entire pH range, particularly in alkaline conditions, is pivotal. Furthermore, the implementation of heterogeneous structures offers a viable approach to improve the efficiency of electrocatalytic hydrogen evolution. − By comprehensively considering factors such as material composition, vacancy, structure, and electron transfer, catalysts can be engineered to exhibit more efficient, stable, and controllable performance in reactions like water electrolysis.…”

Electronic Structure Regulated Nickel-Cobalt Bimetal Phosphide Nanoneedles for Efficient Overall Water Splitting

“…Among the transition metal-based electrocatalysts, transition metal phosphides (TMPs) have been widely studied due to their abundant and inexpensive raw materials and hydrogenase-like structure, which could effectively reduce the cost of precious metal catalysts [12][13][14][15][16]. As a result, the HER and OER catalytic properties of TMPs have been thoroughly investigated, such as NiCoP nanofibers [17], Ni 2 P-CoP@NC [18], NiP x nanospheres [19], hollow urchin-like FeP [20], and carbon encapsulating MoP [21].…”

Surface engineering assisted CoNiP nanosheet arrays for electrochemical overall water splitting

“…4 Although precious metal Pt and RuO 2 /Ir-based materials are considered to be the most advanced electrocatalysts for the HER and OER in industry, the high cost and element scarcity of these precious metal based electrocatalysts greatly limit their widespread application. 5,6 To solve these problems, it is necessary to design cost-effective and earth-abundant catalysts for water splitting. Transition metal-based electrocatalysts are favored by researchers due to the high earth abundance, diversity, potential stability and theoretical catalytic activity of transition metals, such as transition metal carbides, 7 sulfides, 8 phosphates 9 and selenides.…”
