Robust and stable ruthenium alloy electrocatalysts for hydrogen evolution by seawater splitting

Reconciling structure prediction of alloyed, ultrathin nanowires with spectroscopy

“…Nevertheless, relatively little work has been performed on RuCo alloys, which have been reported to be useful in applications, such as but not limited to batteries 23 and Fischer-Tropsch catalysts 24,25 in addition to electrocatalysts for the hydrogen evolution reaction (HER), 22,[26][27][28][29][30] the hydrogen oxidation reaction (HOR), 31 the oxygen reduction reaction (ORR), 32,33 and the oxygen evolution reaction (OER). 34 Results for RuCo alloys used as electrocatalysts have been especially promising, with the alloys frequently outperforming the Pt standards at lower overall costs.…”

Electrochemical performance of porous Ni-alloy electrodes for hydrogen evolution reaction from seawater electrolysis

“…14 However, $75% of the earth is covered by ocean; therefore, one of the most feasible ways of realizing hydrogen evolution is to catalyze seawater due to the high electrical conductivity of seawater (33.9 mS cm À1 at 25 C) and neutral condition. 15 If the water electrolysis technology can be applied to seawater, a broad prospect will be developed. It will be easier to transform the peak electric energy into hydrogen energy, and provide hydrogen fuel vehicles and relevant medical units and enterprises with strong demand for high purity hydrogen for use.…”

Crystalline Ru0.33Se Nanoparticles‐Decorated TiO2 Nanotube Arrays for Enhanced Hydrogen Evolution Reaction

“…Although Ru is a precious metal with 1/25 price of Pt metal, the low Ru dosage makes its composite system a cost‐effective catalytic material. As a result, various Ru‐based composite materials, such as porous Ru nanomaterial, Ru–MoO 2 nanocomposites, Ru nanoparticles (NPs) dispersed within a nitrogenated holey 2D carbon structure, RuCo and RuCoMo x alloys on Ti foil substrates, Ru‐C 3 N 4 complex supported on carbon,[7a] Ru nanoclusters supported on nitrogen‐doped graphene, RuP x encapsulated in N, P‐codoped hollow carbon nanospheres,[3a] have been designed for electrocatalytic hydrogen evolution reaction. Crystalline RuS 2 nanoparticles were also exploited as cathodic catalysts in the methanol fuel cell and hydrochloric acid electrolysis .…”
