Design of binder-free hierarchical Mo-Fe-Ni phosphides nanowires array anchored on carbon cloth with high electrocatalytic capability toward hydrogen evolution reaction

Self-supported electrocatalysts for the hydrogen evolution reaction

“…For example, the Mo-Fe-Ni phosphides nanowires were prepared on carbon cloth, which shows superefficient alkaline HER performance with an overpotential of 75 mV at the current density of 10 mA cm À2 and superior long-term electrochemical stability for 20 h electrolysis. 112 The improved HER performance could be attributed to the synergistic effects between multiple catalytic centers (Mo, Fe, and Ni), as well as the facilitated evolved-gas escape. In similar research, Wen et al provided a general strategy for fabricating self-supported nanoporous Cu-doped CoP nanorod arrays on CC (Cu-CoP NRAs/ CC) via a hydrothermal method followed by a low-temperature phosphatization route, showing enhanced HER performance in a wide pH range.…”

Ultra-thin carbon layer encapsulated NiCoP coralline-like catalysts for efficient overall water electrolysis

“…10 NiCo-based bimetallic phosphides as bifunctional catalysts have attracted broad attention, which is because the synergy of different metal atoms results in redistribution of electrons and promotes the improvement of catalytic activity for water electrolysis. [11][12][13][14] For instance, Mou et al employed density functional theory (DFT) to reveal that all calculated facets ((111), (001), and (100)) of NiCoP had good catalytic activities for the HER and exhibited metallic characteristics with none-zero density of states data at the Fermi level. 15 Generally, NiCobased bimetallic phosphides still have difficulty practically catalyzing water electrolysis, due to factors such as lacking accessible active sites, an inappropriate electron structure around active sites, insufficient electrical conductivity and unsatisfactory long-term stability.…”

Self-Supporting Honeycomb Nickel Cobalt Phosphide on Nickel Foam as an Efficient Electrocatalyst for the Hydrogen Evolution Reaction

“…In order to improve the electrical conductivity of the HER catalyst and increase the active sites for better activity, phosphides combined with matrix materials have been considered an effective approach. Nickel foam (NF), − copper foil, , and carbon cloth − have been used as good support substrates to combine with the catalyst without a binder. NF has received extensive attention owing to the high electrical conductivity and unique network structure.…”
