Conventional water electrolysis is represented by hydrogen evolution and oxygen evolution reactions (HER/OER), while the ECR process is represented by the alcohol oxidation reaction and the HER. (b) Ethanol electrolysis cell activity under real conditions (80 °C, Anion exchange membrane (AEM), 2...
Under 10 mA·cm−2 in 1 M KOH solution, the hydrogen evolution potential and oxygen evolution potential of the electrode surface were 200 mV and 217 mV, respectively. Tang et al.12 deposited a Ni3S2 nano-sheet array on a foamed nickel by hydrothermal method. In alkaline media,...
Recently, monolayer molybdenum disulphide (MoS2) has emerged as a promising and non–precious electrocatalyst for hydrogen evolution reaction. However, its performance is largely limited by the low density and poor reactivity of active sites within its b
Oxygen reduction reaction (ORR), oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) are the core reactions of green energy production, conversion and storage systems such as overall water splitting and zinc-air batteries. Due to the advantages of one-dimensional carbon ...
