Electrolytic Reduction of Copper Oxide

Efficient reduction of graphene oxide catalyzed by copper.

We report that copper thin films deposited on top of graphene oxide (GO) serve as an effective catalyst to reduce GO sheets in a diluted hydrogen environment at high temperature. The reduced GO (rGO) sheets exhibit higher effective field-effect hole mobility, up to 80 cm(2) V(-1) s(-1), and lower sheet resistance (13 kΩ □(-1)) compared with those reduced by reported methods such as hydrazine an...

Torque Ripple Reduction of Electrolytic Capacitor-less BLDC Motor Drive

Brushless DC motors called BLDC are used in many industrial and non-industrial applications today for reasons such as very high efficiency, easy control method and high reliability, and their use is increasingly used in mass production applications, especially home appliances. But these motors require the use of an electric drive, even in constant speed applications. Commercialization of these ...

ELECTROLYTIC RECOVERY OF COPPER FROM CHELATED WASTE STREhMS

Electroless plating is a chemical reduction process which depends upon the catalytic reduction of a metallic ion in an aqueous solution containing a reducing agent without the use of electricity (1). Cahill (2) showed that the cupric ion could be reduced autocatalytically with formaldehyde in an alkaline solution. Okinaka (3 ) established that the overall reaction of the catalytic copper platin...

Reduction characteristics of copper oxide in cerium and zirconium oxide systems

The reduction of CuO dispersed on ̄uorite-type oxide catalysts, namely La-doped CeO2 and Y-doped ZrO2 was studied in this work. On both supports distinct copper species were identi®ed as a function of copper content by temperatureprogrammed reduction (TPR) by H2 and CH4, X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRD) and scanning transmission electron microscopy/energy d...
