Generally, the overall reaction of water electrolysis can be divided into two half-cell reactions: hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). HER is the reaction where water is reduced at the cathode to produce H2, and OER is the reaction where water is oxidized at...
Water electrolysis for hydrogen production: from hybrid systems to self-powered/catalyzed devices However, the sluggish kinetics of the oxygen evolution reaction (OER) at the anode significantly hampers the efficiency of this process. In this ... JT Ren,L Chen,HY Wang - 《Energy & Environmental...
ChemInform Abstract: A New Class of Electrocatalysts for Hydrogen Production from Water Electrolysis: Metal Monolayers Supported on Low-Cost Transition Met... WC and W2C surfaces are excellent supports for monolayer amounts of Pt enabling hydrogen evolution reaction (HER) activities comparable to that ...
Water electrolysis enables the storage of renewable electricity via the chemical bonds of hydrogen. However, proton-exchange-membrane electrolysers are impeded by the high cost and low availability of their noble-metal electrocatalysts, whereas alkaline
Next, the required stoichiometric amount of CO2 for the methanol reaction is determined. The separations in the process are assumed to be 100% efficient. Co-adsorbed water during air capture can be used in the electrolyser and the co-produced water during methanol synthesis is recycled. The ...
Suppressing the oxidation of active-Ir(III) in IrOx catalysts is highly desirable to realize an efficient and durable oxygen evolution reaction in water electrolysis. Although charge replenishment from supports can be effective in preventing the oxidatio
Turnover rate can be calculated by normalizing the intrinsic cur-rents to the number of active sites. If the active sites are properly quantified, then the turnover rate will be constant under identical reaction conditions. Reaction kinetics can help in identifying reaction mechanisms and in ...

Establishing a permanent human presence on the Moon or Mars requires a secure supply of oxygen for life support and refueling. The electrolysis of water has attracted significant attention in this regard as water-ice may exist on both the Moon and Mars.
