Continuous and effective hydrogen evolution under high current densities remains a challenge for water electrolysis owing to the rapid performance degradation under continuous large-current operation. In this study, theoretical calculations, operando Raman spectroscopy, and CO stripping experiments confirm that...
Hydrogen evolution reactionHeterostructureWater dissociationA NiO-Rh 2 P heterostructure electrocatalyst was constructed by phosphating the NiO-Rh structure. Due to the high capability of water dissociation by NiO, only 46mV overpotential was demanded to achieve 10mAcm 2 for the NiO-Rh 2 P, which ...

The electrode made of NiSe2exhibits superior electrocatalytic activity in the hydrogen evolution reaction (HER). A low Tafel slope of 31.1 mV per decade is achieved for NiSe2, which is comparable to that of platinum (30 mV per decade). Moreover, the catalytic activity of NiSe2is very ...
Inexpensive yet efficient oxygen evolution reaction electrodes, working in high current densities, remain a pressing challenge for commercial hydrogen energy economy. NiFe (oxy)hydroxides are presented as strategic materials. Herein, a f... S Wu,Y Zhu,G Yang - 《Chemical Engineering Journal》 被引...
The abundant defects and low-electronegativity heteroatoms in the carbon-based framework endow A-Fe2S1N5/SNC with a high loading of 6.72 wt%. Furthermore, A-Fe2S1N5/SNC has a low overpotential of 193 mV for the oxygen evolution reaction (OER) at 10 mA cm−2, outperforming ...
The electrochemical splitting of water into hydrogen and oxygen is considered one of the most promising approaches to generate clean and sustainable energy. However, the low efficiency of the oxygen evolution reaction (OER) acts as a bottleneck in the water splitting process. Herein, interface engine...
The need for sustainable catalysts for an efficient hydrogen evolution reaction is of significant interest for modern society. Inspired by comparable structural properties of [FeNi]-hydrogenase, here we present the natural ore pentlandite (Fe4.5Ni4.5S8) as a direct 'rock' electrode material for hydr...
