Y.Watanabe, inEncyclopedia of Interfacial Chemistry, 2018 Oxygen reduction reaction (O2+4H++4e−→2H2O) Theoxygen reduction reaction(ORR) is an essential process inelectrochemistryfor energy converting on fuel cells. Recent progress has been made in this reaction using size-selected clusters by sev...
By convention, E° for the half-reaction (3) is taken as zero, i.e. E°(H+/1/2H2) = 0.0 V: (3)H+(aq,a = I ) + e− ⇌ 12H2(g, I atm)Remembering that ΔG = -nEF, it follows that the standard free energy change for the half reaction is ΔG...
Electrochemical nitrate reduction reaction offers a sustainable and efficient pathway for ammonia synthesis. Maintaining satisfactory Faradaic efficiency for long-term nitrate reduction under ampere-level current density remains challenging due to the inevitable hydrogen evolution, particularly in pure nitrate sol...
The sulfur reduction reaction (SRR) plays a central role in high-capacity lithium sulfur (Li-S) batteries. The SRR involves an intricate, 16-electron conversion process featuring multiple lithium polysulfide intermediates and reaction branches1–3. Estab
In both eases, silicon monoxide has an important role in the production of silicon carbide. However, a number of problems must first be overcome to produce silicon carbide powder having desirable properties via the above chemistry. One problem is that, at reaction temperatures above about 1150° ...
Stochastic biochemical reaction networks are commonly modelled by the chemical master equation, and can be simulated as first order linear differential equations through a finite state projection. Due to the very high state space dimension of these equat
With an increase in reaction temperature, NH3 adsorption will be disrupted and desorption tends to occur. As such, it is necessary that the catalysts designed for high-temperature SCR should acquire acid sites with sufficient intensity [10]. On the other hand, their redox properties also need ...

In a chemical reaction, reduction and oxidation take place side by side, where the loss of electrons in one substance is oxidation, but the transfer of these lost electrons to another element is reduction. Depending on the type of chemical reaction, reduction may involve molecules, atoms or ion...
