Preparation and characterization of copper oxide nanofibers by microwave-assisted thermal oxidation

In this work, copper oxide fibers were formed by using a microwave-assisted thermal oxidation in atmosphere. Only the pure copper powder was used to be a precursor and heated under microwave irradiation up to 12 min. The copper oxide fibers were characterized by scanning electron microscope (SEM), X...
