Coupling NiSe2-Ni2P heterostructure nanowrinkles for highly efficient overall water splitting

Design and construction of bi-metal MOF-derived yolk–shell Ni2P/ZnP2 hollow microspheres for efficient electrocatalytic oxygen evolution

“…4 To this end, two effective strategies, i.e., construction of three dimensional (3D) hierarchical porous (particularly hollow architectures) and multicomponent hetero-interfaces, have been proposed. [16][17][18][19] Concretely, the former can maximally expose active edge sites on the catalyst surface. The latter can effectively reduce the chemisorption free energy of OH À , promote the desorption of the intermediates from active centers, bring strong synergistic effects, and even increase the number of active centers.…”

“…17 3D NiSe 2 -Ni 2 P/NF merely required an ultralow overpotential of 220 mV to reach a current density of 50 mA cm À2 . 19 Therefore, the purposeful design of 3D hierarchical hollow structures has a direct effect on the electrochemical performance. [20][21][22][23][24][25] However, it is highly challengeable to develop a simple but efficient methodology to fabricate hierarchical hollow TM phosphides with heterointerfaces at the nanoscale as highly efficient OER catalysts.…”

Hollow cobalt-nickel phosphide nanocages for efficient electrochemical overall water splitting

“…In recent years, transition-metal oxides and corresponding transition metal phosphides [21][22][23][24], sulfides [25,26], nitrides [27,28], and selenides [29][30][31] have been extensively studied as non-precious bi-functional electrocatalysts for overall water-splitting. In particular, transition metal phosphides, especially bimetallic transition metal phosphides have attracted significant attentions as bi-functional electrocatalysts for water-splitting owing to their remarkably enhanced catalytic activities [32,33].…”

Two‐Dimensional NiIr@N‐Doped Carbon Nanocomposites Supported on Ni Foam for Electrocatalytic Overall Water Splitting

“…[14][15][16] As a3 dt ransition metal,n ickel (Ni)a nd its derivatives show considerable promise in electrocatalysis owing to their high abundance and unique physical and chemical properties.Avariety of Ni-based materialsh ave been demonstratedt ob ev ery promisingf or the electrocatalytic HER, OER, and even overall water splitting. [17][18][19][20][21][22][23][24] However,f or most of them, the catalytic performance and stability is still unsatisfactory compared with benchmark noble-metal-based catalysts. Moreover,t he survival environment of the water splitting reaction( e.g.,s trong acidic or alkalinem ediums, higho verpotentials) is difficult for Nibased materials, easily leading to corrosion or oxidation of the metal catalysts.…”
