TY - JOUR TI - Enhancing Hydrogen Evolution Electrocatalytic Performance in Neutral Media via Nitrogen and Iron Phosphide Interactions JF - Small Science IS - 7 VL - 1 PB - Wiley N2 - It remains a challenge to develop efficient electrocatalysts in neutral media for hydrogen evolution reaction (HER) due to the sluggish kinetics and switch of the rate determining step. Although metal phosphides are widely used HER catalysts, their structural stability is an issue due to oxidization, and the HER performance in neutral media requires improvement. Herein, a new material, i.e., grapevine-shaped N-doped iron phosphide on carbon nanotubes, as an efficient HER catalyst in neutral media is developed. The optimized catalyst shows an overpotential of 256?mV at a large current density of 65?mA?cm?2, which is even 10?mV lower than that of the commercial 20% Pt/C catalyst. The excellent performance of the catalyst is further studied by combined computational and experimental techniques, which proves that the interaction between nitrogen and iron phosphides can provide more efficient active structures and stabilize the metal phosphide electrocatalysts for HER ID - discovery10132911 KW - ex situ characterization KW - hydrogen evolution reactions KW - iron phosphide KW - KW - nitrogen doping KW - water splitting AV - public Y1 - 2021/07// A1 - Zhao, S A1 - Xie, R A1 - Kang, L A1 - Yang, M A1 - He, X A1 - Li, W A1 - Wang, R A1 - Brett, DJL A1 - He, G A1 - Chai, G A1 - Parkin, IP N1 - © 2021 The Authors.
