Synthesis of Sphere-Like Nano-crystalline Co3O4 Spinel via a Simple Homogeneous Precipitation Method

Abstract

Nano-crystalline Co3O4 spinel powder has been successfully synthesized via a simple, template and surfactant free homogeneous precipitation method in short time followed by heat treatment at low temperature (350°C). The prepared samples were characterized by powder X-ray diffraction, fourier transform infrared spectroscopy, thermal gravimetric analysis and transmission electron microscopy. © 2017 Elsevier Ltd.
