Preparation and characterization of active and cost-effective nickel/platinum electrocatalysts for hydrogen evolution electrocatalysis

A Review of the Application of Heterostructure Catalysts in Hydrogen Evolution Reaction

“…(B) Polarization experiments performed at 0.5 mV/s in nitrogen‐purged solutions for each material in 0.1 mol/L sodium hydroxide solution and in 0.1 mol/L citrate/phosphate buffer pH 7. (C) Cyclic voltammograms obtained for each prepared nickel‐based electrocatalyst in 0.1 mol/L sodium hydroxide solution and in 0.1 mol/L citrate/phosphate buffer pH 7 [44] .

“…TMOs can generate a large number of oxygen vacancies when contacting with the reactants, so that more active sites are bound to metal. [21,34] A [44] Copyright 2019, Elsevier Ltd.…”

“…Sidney Aquino Neto et al prepared nickel-based metal nanoparticles (Ni 99 Pt 01 /C) doped with metal platinum particles by bromide ion exchange method, which not only reduced the cost but also had excellent performance in the electrochemical test (Figure 6). [44] SEM pictures show that platinum metal particles are evenly distributed on the nickel surface. Compared with traditional commercial high-purity platinum, it is superior in initial overpotential and current density, more conducive to hydrogen evolution reaction.…”

Role of functionalized graphene quantum dots in hydrogen evolution reaction: A density functional theory study

“…Generally, Pt-based materials have been regarded as the most effective catalysts for HER [7][8], however, they cannot be used widely and practically due to their scarcity and high cost.…”

Rhodium effects on Pt anode materials in a direct alkaline ethanol fuel cell

“…45 Therefore, the Bromide Anion Exchange (BAE) method considered as a cleaner and simple approach using water as solvent [45][46][47] was used to develop the electrocatalysts. 45,47,48 It consists in exchanging chloride anion by the bromide one as ligand in the complex structure of the metal salt in order to efficiently control the particles growth. Differently from the direct borohydride reduction method, in the BAE synthesis route the use of bromide anion promotes through its size a great steric effect, which stabilizes the particle during the reduction process with sodium borohydride.…”
