Abstract

A novel method suitable for the synthesis of the cobalt oxide (Co ³O ⁴) nanowires at targeted regions is presented in this report. Cobalt (Co) nanobowls synthesized by colloidal crystal directed assembly were transformed into Co ³O ⁴ nanowiresby a simple heat treatment process. Co nanobowls exhibited a two phase (h.c.p. + f.c.c.) microstructure while single phase microstructure was observed for Co ³O ⁴nanowires. Ferromagnetic Co nanobowls showed a dependence of coercivity on bowl size while Co ³O ⁴ exhibited weak ferromagnetic behavior.
