In an effort to elucidate the underlying molecular mechanism that drives such high catalytic activity, density functional theory (DFT) calculations were applied to oxygen evolution reaction (OER) and hydrogen e
Furthermore, it was found that the combination of g-C3N4 with graphene could improve the conductivity and electrocatalytic performance of g-C3N4 for the oxygen reduction reaction (ORR) [273,278], oxygen evolution reaction [279], and HER with catalytic activity even better than metal-based ...
Self-replenishing Ni-rich stainless-steel electrode toward oxygen evolution reaction at ampere-level While much research has been devoted to enhancing the activity of oxygen evolution reaction (OER) catalysts for hydrogen production systems, less attention has been paid to optimizing their cost and long...
Dispersing catalytically active metals as single atoms on supports represents the ultimate in metal utilization efficiency and is increasingly being used as a strategy to design hydrogen evolution reaction (HER) electrocatalysts. Although platinum (Pt) is highly active for HER, given its high cost it...
Abstract The key challenge for scalable production of hydrogen from water lies in the rational design and preparation of high-performance and earth-abundant electrocatalysts to replace precious metal Pt and IrO2for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Although atomic ...
Layered Double Hydroxides in Oxygen Evolution Reaction Shao and his team focus on layered double hydroxides (LDHs), an important kind of two-dimensional materials with wide tunability of the types, molar ratios of the metal elements, and the nature of interlayer anions. They are outstanding catalys...
Water electrolysis is a sustainable approach for hydrogen production by using electricity from clean energy sources. However, both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are kinetically sluggish, causing low efficiency of the electrolysis devices. The currently used nob...

The hydrogen and oxygen isotopes were measured through zinc reaction method and CO2-H2O balance method, respectively, with the measurement precision (mass fraction) of ±2.0‰ and ±0.2‰ (Table 1). Table 1. The result of hydrogen-oxygen stable isotopes in study area Sample NO. Depth ...
2.2.1.1 Hydrogen evolution reaction The hydrogen evolution reaction is one of the most widely studied electrochemical reactions. Volmer, Heyrovsky, and Tafel steps (Reaction 6, Reaction 7, and Reaction 8, respectively) are the most commonly accepted steps in the hydrogen evolution mechanism (Bockris...
