Journal ArticleDOI
Nanostructured Nickel Phosphide as an Electrocatalyst for the Hydrogen Evolution Reaction
Eric J. Popczun,James R. McKone,Carlos G. Read,Adam J. Biacchi,Alex M. Wiltrout,Nathan S. Lewis,Raymond E. Schaak +6 more
TL;DR: The catalytically active Ni2P nanoparticles had among the highest HER activity of any non-noble metal electrocatalyst reported to date, producing H2(g) with nearly quantitative faradaic yield, while also affording stability in aqueous acidic media.
Journal ArticleDOI
Highly active electrocatalysis of the hydrogen evolution reaction by cobalt phosphide nanoparticles.
TL;DR: The activity was essentially unchanged after 400 cyclic voltammetric sweeps, suggesting long-term viability under operating conditions, and CoP is amongst the most active, acid-stable, earth-abundant HER electrocatalysts reported to date.
Journal ArticleDOI
Nanostructured Co2P Electrocatalyst for the Hydrogen Evolution Reaction and Direct Comparison with Morphologically Equivalent CoP
TL;DR: In this article, metal phosphides have emerged as promising Earth-abundant alternatives to platinum for catalyzing the hydrogen evolution reaction (HER) in acidic aqueous solutions.
Journal ArticleDOI
Electrocatalytic and photocatalytic hydrogen production from acidic and neutral-pH aqueous solutions using iron phosphide nanoparticles.
Juan F. Callejas,Joshua M. McEnaney,Carlos G. Read,J. Chance Crompton,Adam J. Biacchi,Eric J. Popczun,Thomas R. Gordon,Nathan S. Lewis,Raymond E. Schaak +8 more
TL;DR: Under UV illumination in both acidic and neutral-pH solutions, FeP nanoparticles deposited on TiO2 produced H2 at rates and amounts that begin to approach those of Pt/TiO2, therefore FeP is a highly Earth-abundant material for efficiently facilitating the HER both electrocatalytic and photocatalytically.
Journal ArticleDOI
Amorphous Molybdenum Phosphide Nanoparticles for Electrocatalytic Hydrogen Evolution
Joshua M. McEnaney,J. Chance Crompton,Juan F. Callejas,Eric J. Popczun,Adam J. Biacchi,Nathan S. Lewis,Raymond E. Schaak +6 more
TL;DR: Amorphous molybdenum phosphide (MoP) nanoparticles have been synthesized and characterized as electrocatalysts for the hydrogen evolution reaction (HER) in 0.50 M H2SO4 (pH 0.3).
