This invention relates to a process for the preparation of aldonic acids (in particular gluconic acid) by oxidation of aldoses with oxygen or with a gas containing oxygen, in the presence of supported bimetallic catalysts based on gold a... M Rossi,S Biella,M Comotti 被引量: 15发表: 200...
Oxygen-containing carbons are promising supports and metal-free catalysts for many reactions. However, distinguishing the role of various oxygen functional groups and quantifying and tuning each functionality is still difficult. Here we investigate the r
The moles of dissolved oxygen per mole of chromium present in the liquids have been determined for some compositions. 展开 关键词: direct energy conversion materials science inorganic, organic, physical and analytical chemistry calcium oxides chemical reactions chromium oxides lanthanum oxides mhd ...
In summary, we propose that chemically inert elements such as He have a prevalent propensity to react with ionic compounds that have unequal numbers of cations and anions. The He atoms do not form any chemical bonds with the ions in the compounds. However, the insertion of He atoms will low...

Ovac1/Ovac2 formation on the surface would trigger further reactions of H2O adsorption and splitting,which refilled the oxygen vacancy and ensured the considerable stability of the PbO2 (110) surface.Multiple H2O dissociation pathways were proposed on PbO2 (110) with oxygen vacancy sites:the acid...
However, little had been explored about the chemical properties and reactivity of the mononuclear copper-active-oxygen complexes due to the lack of appropriate model compounds. Thus, a great deal of effort has recently been made to ... Itoh,Shinobu - 《Acc Chem Res》 被引量: 4发表: 2015年...
energy. The most reactive elements and compounds may ignite spontaneously or explosively. They generally burn in water as well as the oxygen in the air. Reactivity is dependent upontemperature. Increasing temperature increases the energy available for a chemical reaction, usually making it more likely...
The chemical looping air separation (CLAS) is a novel method for producing high-purity oxygen, which can be effectively integrated to oxy-fuel power plants. CuO/Cu2O, Mn2O3/Mn3O4, and Co3O4/CoO have been found to be the most thermodynamically suitable oxidation pairs for the CLAS process...
