Bimetal phosphide as high efficiency and stable bifunctional electrocatalysts for hydrogen and oxygen evolution reaction in alkaline solution

Abstract

The CoNiP structure is prepared by a simple “in situ growth-ion exchange-phosphating” method. The CoNiP-0.15 M shows the excellent HER and OER performance, also it exhibits high stability with high current density at room temperature and 80 °C.

Ni2–xMnxP Nanoparticles as Earth-Abundant Precatalysts for Electrochemical Water Oxidation

“…In the supported precatalyst, the Ni 2p 3/2 spectrum shows peaks at 853.7 eV, assigned to Ni-phosphide, 22 and 856.2 eV, which can be assigned either to Ni 2+ or Ni 3+ (differentiating between these two species is extremely challenging). 23,24 In contrast, the spectrum of Mn 2p 3/2 exhibits peaks at 641.4 and 642.8 eV, attributed to Mn 3+25 and Mn 4+ .…”

Boosting oxygen evolution reaction rates with mesoporous Fe-doped MoCo-phosphide nanosheets

“…TMPs possess metal sites and abundant oxygen vacancies (V O ), which could serve as catalysts for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) in alkaline conditions. 22,23 Furthermore, they offer a combination of high catalytic activity, excellent electrical conductivity, cost-effectiveness, abundance of constituent elements, stability, and versatility, making them promising electrocatalysts for efficient water electrolysis. 24,25 In addition, the favorable structures, well-dened surface morphology, and ample surface area of these materials contribute to an abundance of active sites, thereby bestowing them with distinct properties for catalytic reactions.…”
