Construction of an iron and oxygen co-doped nickel phosphide based on MOF derivatives for highly efficient and long-enduring water splitting

Abstract

(Fe0.1Ni0.9)2P(O)/NF is one of the excellent water-splitting electrocatalysts among non-precious metal electrocatalysts.

Two‐Dimensional NiIr@N‐Doped Carbon Nanocomposites Supported on Ni Foam for Electrocatalytic Overall Water Splitting

“…[14][15][16] As a3 dt ransition metal,n ickel (Ni)a nd its derivatives show considerable promise in electrocatalysis owing to their high abundance and unique physical and chemical properties.Avariety of Ni-based materialsh ave been demonstratedt ob ev ery promisingf or the electrocatalytic HER, OER, and even overall water splitting.

Moreover,t he survival environment of the water splitting reaction( e.g.,s trong acidic or alkalinem ediums, higho verpotentials) is difficult for Nibased materials, easily leading to corrosion or oxidation of the metal catalysts.…”

“…As a 3d transition metal, nickel (Ni) and its derivatives show considerable promise in electrocatalysis owing to their high abundance and unique physical and chemical properties. A variety of Ni‐based materials have been demonstrated to be very promising for the electrocatalytic HER, OER, and even overall water splitting [17–24] . However, for most of them, the catalytic performance and stability is still unsatisfactory compared with benchmark noble‐metal‐based catalysts.…”

MoP@C Supported on Absorbent Cotton as a Highly Efficient Catalyst towards Hydrodechlorination Reaction

“…The decrease in activity was principally because excess carbon in the catalysts not only resulted in insufficient MoP content, but also covered the active sites, which made it difficult for trichloroethylene to contact the active component and hindered mass transfer . Throughout experimental process, the excess carbon content may be due to insufficient calcination time in the muffle furnace, leading to most of the carbon remaining in the samples.…”

Metal‐organic frameworks‐derived novel nanostructured electrocatalysts for oxygen evolution reaction

“…It is noted that FeNi‐MOF displays superior electrocatalytic OER performances with low overpotentials of 150 mV at 100 mA/cm 2 and Tafel slopes of 38.7 mV/dec in alkaline media, and showcases exceptional catalytic durability for more than 100 h at the current densities. Recently, Lin et al 127 made an Fe and O co‐doped nickel phosphide ((Fe 0.1 Ni 0.9 )2P(O)) by phosphating MOF derivatives underpinned by Ni foam in a bid to realize efficient water splitting. In 1.0 M KOH, the (Fe 0.1 Ni 0.9 )2P(O)/NF electrode only called for an overpotential of 240 mV to reach 100 mA/cm 2 for the OER performance.…”
