Enhanced hydrogen evolution reaction on hybrids of cobalt phosphide and molybdenum phosphide
Production of hydrogen from water electrolysis has stimulated the search of sustainable electrocatalysts as possible alternatives. Recently, cobalt phosphide (CoP) and molybdenum phosphide (MoP) received great attention owing to their superior catalytic activity and stability towards the hydrogen evolution reaction (HER) which rivals platinum catalysts. In this study, we synthesize and study a ...
متن کاملHighly branched cobalt phosphide nanostructures for hydrogen-evolution electrocatalysis
CoP nanostructures that exposed predominantly (111) crystal facets were synthesized and evaluated for performance as electrocatalysts for the hydrogen-evolution reaction (HER). The branched CoP nanostructures were synthesized by reacting cobalt(II) acetylacetonate with trioctylphosphine in the presence of trioctylphosphine oxide. Electrodes comprised of the branched CoP nanostructures deposited...
متن کاملMolybdenum phosphide: a new highly efficient catalyst for the electrochemical hydrogen evolution reaction.
Molybdenum phosphide was adopted as a new electrocatalyst for the hydrogen evolution reaction for the first time, exhibiting an excellent electrocatalytic activity with a small Tafel slope of 60 mV dec(-1), which is amongst the most active, acid-stable, earth abundant HER electrocatalysts reported to date.
متن کاملShort communication Hydroxyapatite supported Nickel catalyst for hydrogen production
Hydroxyapatite (HAp) supported Nickel (Ni) catalyst was prepared using wet impregnation method. A series of Ni/HAp catalysts have been prepared by varying the amount of nickel viz., 3, 6 and 12 %. The highest Brunauer-Emmett-Teller (BET) surface area of 92.18 m/g was noticed for a catalyst composition containing 3% nickel loading. The scanning electron microscopy (SEM) studies revealed a smooth...
متن کاملElectrocatalytic hydrogen evolution using amorphous tungsten phosphide nanoparticles.
Amorphous tungsten phosphide (WP), which has been synthesized as colloidal nanoparticles with an average diameter of 3 nm, has been identified as a new electrocatalyst for the hydrogen-evolution reaction (HER) in acidic aqueous solutions. WP/Ti electrodes produced current densities of -10 mA cm(-2) and -20 mA cm(-2) at overpotentials of only -120 mV and -140 mV, respectively, in 0.50 M H2SO4(aq).
