Rational design of Pt-Ni-Co ternary alloy nanoframe crystals as highly efficient catalysts toward the alkaline hydrogen evolution reaction.
The rational design of highly efficient electrocatalysts for the hydrogen evolution reaction (HER) is of prime importance for establishing renewable and sustainable energy systems. The alkaline HER is particularly challenging as it involves a two-step reaction of water dissociation and hydrogen recombination, for which platinum-based binary catalysts have shown promising activity. In this work,...
متن کاملApplication of Pd-Substituted Ni-Al Layered Double Hydroxides for the Hydrogen Evolution Reaction
Clean production of hydrogen from electrochemical water splitting has been known as a green method of fuel production. In this work, electrocatalytic hydrogen evolution reaction (HER) was investigated at new prepared layered double hydroxides (LDH) in acidic solution. NiAl/carbon black (CB) LDH was monitored using x-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scannin...
متن کاملPreparation of Ni-P-CeO2 electrode and study on electrocatalytic properties for hydrogen evolution reaction
In this study ternary Ni-P-CeO2 catalysts were first synthesized by the Co-electrodeposition method on a copper substrate and then characterized by means of microstructural and electrochemical techniques toward a hydrogen evolution reaction (HER). Also, for comparison other catalysts such as Ni-CeO2, Ni-P, and Ni were prepared and characterized by the same methods. The microstructure of the inv...
متن کاملRapid Synthesis of Rhodium–Palladium Alloy Nanocatalysts
Noble metals are widely used as catalysts in a variety of key industrial processes. In particular, rhodium is used to catalyze the reduction of NOx to N2 and O2 in exhaust gas abatement and is also used in the conversion of bulk hydrocarbon feedstocks and syngas into more highly oxygenated hydrocarbons (e.g. , hydroformylation). 2] Palladium also plays a myriad of critical roles, including CO-t...
متن کاملElectrocatalytic Activity of the Ni57.3Co42.7 Alloy for the Hydrogen Evolution
The hydrogen evolution reaction (HER) on Ni57.3Co42.7 alloy and its main components, polycrystalline nickel and cobalt was investigated in 1.0 mol L–1 NaOH solution at 20 °C using cyclic voltammetry, pseudo-steady-state linear polarization and electrochemical impedance spectroscopy methods. The purpose of investigation was to evaluate the effect of cobalt on the intrinsic catalytic activity of ...
