Two dimensional (2D) porous cobalt oxide (Co3O4) nanoflake (CONF) arrays are prepared by a facile sonochemical synthesis followed by calcination at 300 °C for 3 h. The successful synthesis and phase purity of CONFs were confirmed using X-ray diffraction (XRD) and Raman spectroscopy. Field emission s...
