Preparation of copper oxide nanowire-based conductometric chemical sensors CuO nanowires (NWs) were grown by thermal oxidation of metallic Cu thin layer deposited by sputtering on different substrates. Optimal growth parameters we... D Zappa,E Comini,R Zamani,... - 《Sensors & Actuators B Chemica...
Carbon monoxide oxidation activities over Cu, Cu2O, and CuO were studied to seek insight into the role of the copper species in the oxidation reaction. The activity of copper oxide species can be elucidated in terms of species transformation and change in the number of surface lattice oxygen ...
Oxidation of copper in controlled clean air and standard laboratory air at 50°C to 150°C Analysis of the growth of the oxide film formed on copper at moderately low temperatures (150 to 50°C) in controlled clean air and typical laboratory air environments has been carried out. Film ...
Thus the oxidation process was within the copper preplated layer, and the main product of the oxidation was Cu2O. It was found that the large column grain of the oxide film on the copper alloy with a copper plated layer, favored the diffusion of copper or oxygen atoms that led to the ...
The oxidation kinetics of copper thin films have been studied at temperatures below 200°C in air. The protection of copper from oxidation can be achieved by alloying copper film with Ti, Pd, Cr, or Al. The influence of the composition and microstructure to the oxidation rate has been studie...
ChemInform Abstract: Combustion of Soot Deposits from Diesel Engines on Mixed Oxides of Vanadium Pentoxide and Cupric Oxide. The soot particles (also known as the particulate matter) are harmful to the respiratory system. Applying the principles of a cyclone and the electrostatic... AF Ahlstroem,...
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 ...
Free copper oxide seems to be responsible for this first plateau activity. For the active species of the second plateau, which shows an approximate conversion of 40%, we propose a new crystalline copper-oxalate (moolooite) phase produced during the reaction process, and a `surface spinel' ...
2. Copper-based catalysts for AOPs Copper-based catalysts (CBC) have in recent years emerged as auspicious catalysts in AOPs owing to their earth abundance, easy preparation, minimal toxicity, good stability, cost-effectiveness, and unique electronic configurations. A variety of CBC have been synthe...
Copper OxideMass GainPure CopperIn this study, the high-temperature oxidation resistance of copper and copper-aluminum alloys in air was investigated using thermo-gravimetric analysis. Upon heating in air, copper starts to noticeably oxidize at temperatures above 400掳C. It was found that as the ...
