When iodine was reacted with aqueous alkaline earth metal oxides (MgO, CaO, SrO and BaO) both metal iodate and iodide were formed. However these reactions were never complete. The percentage of products obtained was increased with excess I 2 and water, and higher molecular weight oxide. Both...

Oxygen evaluation reaction (OER) is the most important reaction in hydrogen production from water splitting. Here we developed metal-carbon nanotubes (M-CNTs) hybrids with high metal oxide catalyst loading synthesized by arc-discharge and chemical vapor deposition (CVD) methods as electrocatalysts for...

During the aluminum + water reaction, aluminum ions and electrons are removed in separate steps at different sites on the surface. Ions are removed nearly uniform over the entire surface, which is covered at all times with a thin amorphous oxide film. The outer surface of this oxide is first...
Understanding the sensing mechanism of metal oxide semiconductors is imperative to the development of high-performance sensors. The traditional sensing mechanism only recognizes the effect of surface chemisorbed oxygen from the air but ignores surface lattice oxygen. Herein, using in-situ characterizations,...

Photoredox nickel catalysis has emerged as a powerful strategy for cross-coupling reactions. Although the involvement of paramagnetic Ni(I)/Ni(III) species as active intermediates in the catalytic cycle has been proposed, a thorough spectroscopic investi
The first phase, called the Volmer phase (discharge reaction), is the adsorption reaction of the electrochemical hydrogen ions. In the same stage, the reaction of a water molecule or proton with an electron within an alkaline/acidic medium generates an atom of hydrogen (H*) adsorbed on the ...
