2011年5月15日 · CuO nanowires are synthesized by heating Cu foil, rod and grid in ambient without employing a catalyst or gas flow at temperatures ranging from 400 to 800 °C for a duration of 1–12 h. Scanning electron microscopy (SEM) investigation reveals the formation of nanowires.

2015年9月25日 · Large-area freestanding graphene films are facilely fabricated by reducing graphene oxide films on recyclable Cu foils in H 2 -containing atmosphere at high temperature. Cu might act as...

2020年5月27日 · In our experiment, we first developed a pre-oxidation treatment technique to generate a large grain seed with a high-index facet in a commercial polycrystalline Cu foil. The Cu foils were...

Results show that ZnO and CuO nanowires are formed on brass and Cu wires, respectively. The ZnO nanowires are branched and CuO nanowires are straight with tapered morphology.

2019年6月1日 · We show that the oxidation of Cu NPs can be hampered through air oxidation experiments up to 400 °C by thermogravimetric analysis (TGA). Whereas unprotected Cu NPs undergo fast oxidation at room temperature, we demonstrate here that the oxidation onset temperature can be raised up to more than 200 °C by few nanometer–thick silver shells.

The cyclic voltammetry, galvanostatic charge discharge as well as electrochemical impedance spectroscopic results are justifying the potential candidature of CuO/Cu(OH)2 nanostructures on copper...

2020年7月15日 · A free standing binder-free 3D Cu(OH) 2 nanorod network film was fabricated directly onto a Cu foil current collector using a simple and cost-effective surface chemical oxidation method. The thickness of the used Cu foil is 15–17 μm.

Large-area freestanding graphene films are facilely fabricated by reducing graphene oxide films on recyclable Cu foils in H2-containing atmosphere at high temperature. Cu might act as eficient...

continuous ultrasonication to separate SG and Cu foil. To ascertain the suitable oxidation temperature, the TGA curves of individual SG and Cu foil were both recorded under air and N2 atmospheres. The TGA curve of the SG sample tested under a N2 atmosphere (refer to Fig. S9a) shows a weight loss of ~7 wt.% as the temperature

2018年10月1日 · In this study, TGA under air flow has been utilized to research Cu foil oxidation rate and Arrhenius relationship with isothermal temperature to determine the thermal condition. This work also utilize the transfer EMC molding on Cu foil as a pudding structure and using shear testing method to determine the EMC/Cu interfacial adhesion ...
