Constructing Fe/Ni atomic interfaces in Fe-doped Ni(OH)₂with single-phase structures for efficient oxygen evolution

Abstract

Fe dopant is acknowledged to be extremely efficient strategy in catalytic performance enhancement for oxygen evolution reaction (OER). However, the influence of Fe distribution excepting from concentration on OER catalysis...

Ni3Se4/Fe(PO3)2/NF composites as high-efficiency electrocatalysts with a low overpotential for the oxygen evolution reaction

“…13–15 However, these noble metal catalysts cannot be employed for large-scale commercial applications because of their limited multifunctional performance, 8 high price, small earth reserves, and poor stability. 16,17 The 3d transition metal-based catalysts, such as layered double hydroxides (LDHs), 18 metal oxides (hydroxides), 19,20 phosphides, 21,22 sulfides, 23 selenides, 24 nitrides, 25 metal phosphates, 26 and carbides, 27 have the characteristics of abundant reserves, low cost, and high efficiency, and they have been widely used in electrocatalytic water splitting research and are potential candidates for the electrocatalytic OER. 26…”

Synergistic reductive catalytic effects of an organic and inorganic hybrid covalent organic framework for hydrogen fuel production

“…[1][2][3] Nonetheless, the depletion of these non-renewable resources, as well as the environmental adverse effects of their use, has prompted substantial research into advanced methods for capturing and storing clean and renewable energy, such as solar, 4 wind and water energy. [5][6][7][8] Due to its high energy density and zero pollutant emission, H 2 is expected to become a common fuel in many energy conversion devices in the near future. 9,10 Fuel cells, [11][12][13] water electrolysers, and rechargeable metal-air batteries are only a few examples of energy conversion devices based on electrocatalysis.…”

Heterostructured electrocatalysts for the oxygen evolution reaction

“…Green hydrogen production offers environmental sustainability, flexible production capabilities, high purity, and valuable oxygen by-products. 5–7 According to the International Hydrogen Council, water electrolysis hydrogen production costs are expected to be on par with gray hydrogen by around 2035. By 2050, green hydrogen will likely have a clear competitive advantage.…”
