Reaction of hydrogen evolution on Co−Mo (W) and Ni−Re electrolytic alloys in alkaline media

Advanced anticorrosive coatings based on tungsten, its alloys and compounds

“…Одним из возможных применений сплавам вольфрама является использование их в качестве перспективных каталитически-активных слоев для реакции выделения водорода [56], но существует и перспектива их использования в качестве антикоррозионных покрытий [57,58]. Отмечается [57], что введение вольфрама в сплавы никеля приводит к улучшению его антикоррозионных свойств за счет снижения пористости осаждаемого слоя.…”

Pure pompon structured Co–Mo alloy electro-deposited from ethylene glycol solution and used as electrocatalysts for hydrogen evolution reaction

“…In order to lower the use of these traditional non-renewable fossil fuels, there is an incentive to develop and employ more and more renewable, sustainable and clean energy technologies including solar energy, tides energy, wind energy, hydrogen-fueled, and biomass technologies [4][5][6]. The production of hydrogen based on electrolysis of water can be employed as a potential and energetic alternative due to the fact that hydrogen presents these advantages of being pollution-free, high-energy-density and zero carbon dioxide emissions and the technology can obtain high purity hydrogen [7][8][9][10][11][12][13][14][15][16][17][18][19]. However, at present, preparing hydrogen gas from electrolysis is relatively expensive principally due to the use of noble-metal electrocatalysts [20], thus, in order to minimize hydrogen production cost, it has been quite urgent to develop some cheap and high-performance catalysts with low overpotential, high electronic conductivity, good charge transfer kinetics and long-term stability for hydrogen evolution reaction (HER) and then they can be employed in the practical hydrogen production.…”

“…In recent decades, non-noble transition metals catalysts including metal nitrides [16,21], metal sul des [17,22], metal selenides [15,23] and transition-metal alloys [8, [10][11][12]24] had been successfully prepared and exhibited much absorbing consequence. Among these catalysts, Co-Mo alloy and its composite materials are important and promising electrocatalysts for HER due to the fact that these electrode materials exhibit many outstanding properties such as long-term electrochemical stability, good electrical conductivity, high corrosion resistance, outstanding catalytic activity and low overpotential for the HER [8-12, 15, 19].…”
