Low-dimensional transition metal sulfide-based electrocatalysts for water electrolysis: overview and perspectives

Abstract

Hydrogen prepared by electrocatalytic decomposition water ("green hydrogen") has the advantages of high energy density, clean and pollution-free, which is an important energy carrier to face the problem of energy...

Preparation of carbon coated hyperdispersed Ru nanoparticles supported on TiO2 HER electrocatalysts by dye-sensitization

“…Therefore, the design and preparation of low platinum, non-platinum and metal-free HER electrocatalysts have become the current research focus. 6–9…”

“…Therefore, the design and preparation of low platinum, non-platinum and metal-free HER electrocatalysts have become the current research focus. [6][7][8][9] In recent years, people have done a lot of research work on the development of alternative platinum based HER electrocatalysts, and a large number of representative new catalysts have emerged, such as low-platinum, non-platinum, nonprecious metal and metal-free types. [10][11][12] One of the common methods is to reduce the amount of precious metal platinum and design low-platinum catalysts such as core-shell (the shell is a thin layer of platinum), alloy (Pt-M, M represents Ru, Pd, Co, Ni, Fe, etc.)…”

Highly N‐Doped Fe/Co Phosphide Superstructures for Efficient Water Splitting

“…Nowadays, the development of high-performance yet inexpensive precious metal substitutes to promote water splitting has attracted much attention. [3][4][5][6] Inexpensive transition-metal phosphides (TMPs) are a typical class of promising substitutes because of their optimal electrical conductivity and satisfactory structural stability under harsh working conditions. [7] The TMPs used for the HER were first reported by Raymond E. Schaak et al, [8] from then on, TMPs were used extensively to promote the HER and OER, especially those containing Fe, Co and/or Ni.…”

Defect-rich carbon-coated nickel–cobalt alloy nanoparticles enhanced the OER catalytic activity through surface reconstruction

“…7 Therefore, the development of abundant and low-cost non-precious metal catalysts is the key to achieving the industrial application of electrocatalytic decomposition of water reactions. 8 Among various catalysts, nickel-cobalt-based materials are widely used in multiphase catalysis 9 due to their advantages of environmental friendliness, 10 abundant reserves, low cost, 11 and multivalent state. 12 However, limited by the limitations of the ability of different oxygen intermediates in OER optimization of a single metal component, their electrocatalytic activity needs to be further improved.…”
