IN SITU ESR MONITORING OF CUH-ZSM-5 UP TO 500-DEGREES-C IN FLOWING DRY MIXTURES OF NO(NO2), C3H6(C2H5OH), AND EXCESS O-2 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...
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 ...
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...
In thenomenclatureofinorganic chemistry, the oxidation number of an element that may exist in more than one oxidation state is indicated by a roman numeral in parentheses after the name of the element—e.g., iron(II) chloride (FeCl2) and iron(III) chloride (FeCl3). ...
"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.
Evidence has been obtained for a transition from an "oxidized" towards a "reduced" state of the catalyst under the simulated PROX reaction conditions as a function of the reaction temperature, leading to different active species under the reaction conditions. Both CO oxidation activity and PROX ...
Carbonreacts withmercury(II) oxide (acompoundin which mercury has a bonding capacity expressed as +2;see belowOxidation-state change) to producecarbon dioxideand mercurymetal. This reaction can be written in equation form: Carbon, receiving oxygen, is oxidized; mercury(II) oxide, losing oxygen,...
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...
