Br-induced P-poor defective nickel phosphide for highly efficient overall water splitting

Self-supported electrocatalysts for the hydrogen evolution reaction

“…Nickel phosphide catalysts have attracted considerable attention owing to their great catalytic activities for the HER. 205–210 Yan et al constructed 3D self-supported, hierarchical, and edge-rich Ni 2 P nanosheet arrays on NF (Ni 2 P NSs-NF) for the HER. 211 Several in-plane nanopores were produced on the Ni 2 P NSs in the phosphatization step, benefiting from the electrolyte soakage and H 2 molecules release.…”

Interfacial engineering of FeWO4/Fe2O3 homometallic heterojunctions for synergistic electrocatalytic water splitting

“…6,7 In recent years, extensive research has been conducted on the design and synthesis of low-cost nonnoble metal electrocatalysts, such as metal oxides, chalcogenides, carbides, phosphides, nitrides, and borides. [8][9][10] These transition metal oxides can improve HER performance by promoting water dissociation and enhancing H atom adsorption, thanks to their unique charged properties. 11,12 Fe 2 O 3 , as one of the most abundant and cost-effective minerals, has great potential as an electrocatalyst.…”

NiFeCu phosphides with surface reconstruction via the topotactic transformation of layered double hydroxides for overall water splitting

“…11 Using TMPs some results have been achieved in water splitting, but some bimetallic transition-metal phosphides reported still require large voltages to drive overall water splitting to produce hydrogen and oxygen. 12 To improve the catalytic activity of bimetallic transition-metal phosphides, researchers have employed various strategies, such as modifying the electronic structure, 13,14 modulating morphological features, 15 and changing the phase interface to increase activity. 16 For example, it has been reported that NiFeP@N-CS (N-CS: nitrogen-doped carbon sponge) requires a driving voltage of 1.63 V to catalyze water splitting; 17 the reported NiFeP@SG (SG: sponge-like strutted graphenes) requires a voltage of 1.54 V to promote water splitting to generate hydrogen and oxygen.…”
