A novel method to synthesize cobalt oxide (Co3O4) nanowires from cobalt (Co) nanobowls

A novel method to synthesize cobalt oxide (Co3O4) nanowires from cobalt (Co) nanobowls

A novel method suitable for the synthesis of the cobalt oxide (Co3O4) nanowires at targeted regions is presented in this report. Cobalt (Co) nanobowls synthesized by colloidal crystal directed assembly were transformed into Co3O4 nanowires by a simple heat treatment process. Co nanobowls exhibited a...
