Using X-ray absorption spectroscopy (XAS) at the Cu L(2,3) and Co L(2,3) edges, we demonstrate that the valence state of copper in the thiospinel carrollite (CuCo(2)S(4)) is Cu(+) with a d count of Cu d(9.8). The Co has a d count of d(6.4), so that the highly cova...
Variations in the oxidation state of copper during CO catalytic oxidation over powdered CuO and Cu 2 O in a gas mixture of 5% CO/He and air (O 2 ) were investigated by means of an appropriate combination of evolved gas analysis, thermogravimetry, XRD, and FT-IR in the temperature range ...
A flow cell was used for ESR monitoring of the state of copper ions in Cu-ZSM-5 in situ at 20-500 degrees C in a He stream containing C3H6 (or C2H5OH), NO,... Kucherov AV.Jen HW.Shelef M.Gerlock JL. - 《Journal of Catalysis》 被引量: 0发表: 1995年 加载更多来源...
"Oxidation" and "Oxidization" essentially refer to the same chemical process, where a substance loses electrons or increases its oxidation state, often involving oxygen. The "oxidation" being more commonly used.
Copper nanoparticles (CuNPs) are attractive as a low-cost alternative to their gold and silver analogues for numerous applications, although their potential has hardly been explored due to their higher susceptibility to oxidation in air. Here we show the
This value is significantly lower than the one (~ 3.64) expected on the basis of the value determined for the Na to Co stoichiometry ratio, x. The "lower-than-expected" value for the Co oxidation state may be alternatively explained by presence of oxygen vacancies or excess protons. More...
Effect of PDS coating on structural and surface properties Cu(II)Y was prepared by ion exchange of the zeolite NaY with copper(II) nitrate and reduced to Cu(I)Y selectively via vapor-induced reduction (VIR) in term of our previous reports37,38. To tailor the microenvironment of Cu(I)Y,...
With the transfer of two of its electrons, the zinc metal is oxidized, becoming an aqueous zinc ion, while the copper(II) ion, gaining electrons, is reduced to copper metal. Net change is the transfer of two electrons, lost by zinc and acquired by copper. ...
