Universal synthesis of rare earth-doped FeP nanorod arrays for the hydrogen evolution reaction

Abstract

A universal plasma-assisted strategy is proposed for the fabrication of rare earth (RE)-doped FeP nanorod arrays (RE-FeP) as a kind of potential electrocatalyst for the hydrogen evolution reaction (HER). The...

Constructing Fe–N-doped porous carbon nanofibers for a pH-universal ORR and switchable, superior Zn–air batteries

“…2f) exhibit two groups of peaks, at 710.8 and 724.3 eV for Fe 2+ , and 713.1 and 726.5 eV for Fe 3+ along with two satellite peaks. 34,35 The 2p peak in Zn XPS spectra cannot be divided into more peaks because of the low content (Fig. S3b†); however, the residual Zn species possibly catalyze the ORR performance, which was also verified in previous literatures.…”

Ultrathin core–shell–satellite structured Au@PtPd@Pt nanowires for superior electrocatalytic hydrogen evolution

“…In particular, the poor stability of OER catalysts under acidic conditions necessitates the development of novel engineering strategies to create multifunctional electrode materials suitable for the HER in neutral or alkaline electrolytes. 4–8 Although extensive research has been focused on Pt-free catalysts to reduce costs, while ensuring reasonable efficiency, a discernible performance disparity between Pt-free and Pt-based counterparts remains evident. Pt-based materials currently continue to demonstrate state-of-the-art catalytic activity for the HER due to the rapid recombination of hydrogen intermediates (Tafel step, 2H* → H 2 ), but are largely restricted by the poor activation for the dissociation of water (Volmer step, 2H 2 O + 2e − → H 2 + 2HO − ), and the prohibitive costs and scarce reserves.…”

Boosting the hydrogen evolution reaction on NiTe monolayers via defect engineering: a computational study

“…4–6 In this context, a promising electrocatalyst to minimize the overpotential and energy barrier is highly desirable for the highly efficient hydrogen evolution reaction (HER). 7–10 To date, Pt-based materials 11–14 are regarded as the most effective HER catalysts due to their optimal binding strength with hydrogen, but their high cost and scarcity greatly hamper their practical application. Thus, searching for stable, low-cost, and high-performance alternatives to Pt-based catalysts is highly desirable for electrochemical H 2 generation.…”
