Oxygen evolution reaction (OER) suffers from four-electron transfer, sluggish kinetics and high energy requirements, limiting the development of new energy technologies such as hydrogen production from water electrolysis. In recent years, non-
The rationalization for the calculated energetics is related to the values of the ionization potential (IP) of the Rieske cluster and the electron affinity (EA) of the mononuclear iron complex: the latter is computed to be higher than the former, when dioxygen is bound to the metal. The...

Metal have 1 to 3 electrons in the outer shell whereas non-metal have 4 to 8 electrons. Metal oxide is formed when a metal reacts with oxygen and forms electrovalent or ionic bonds, e whereas non-metals form non-metal oxides when they react with oxygen and mostly form covalent bonds. ...
Binary metal oxides are attractive anode materials for lithium-ion batteries. Despite sustained effort into nanomaterials synthesis and understanding the initial discharge mechanism, the fundamental chemistry underpinning the charge and subsequent cycles
We demonstrate the translation of a low-cost, non-precious metal cobalt phosphide (CoP) catalyst from 1 cm2 lab-scale experiments to a commercial-scale 86 cm2 polymer electrolyte membrane (PEM) electrolyser. A two-step bulk synthesis was adopted to produce CoP on a high-surface-area ca...
However, both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) associated with water electrolysis are kinetically sluggish, leading to low efficiency in corresponding electrolysis devices. In addition, current electrocatalysts that can catalyze both HER and OER to practical ...
Some example of non – metals are carbon,oxygen, Sulphur, phosphorous, and many more. Uses of Non Metals Many non-metals like chlorine, Sulphur, iodine are very useful for medicinal purposes. Non-metal like oxygen is very essential for our life forrespiration. ...

This interatomic distance change in the metal atoms is a well-known feature in the surface study of oxidized metals, as observed at the initial stage of oxidation, such as the oxygen-adsorbed surface of silver NPs34. Thus, the constant atomic arrangement of Cu NPs with a periodicity of 0....
