| Abstract: |
| Transition metal oxides and phosphides including Co3O4 and CoP3 have attracted lots of attention as an efficient promising class especially as alternative anode-material for lithium ion battery (LIB) because of their excellent catalytic, electrocatalytic and magnetic properties. Therefore, the synthesis of such nanomaterials by facile, safe and low-cost methods is favorable. In present study, we report the synthesis of Co3O4-CoP3 nanocomposite using a facile mechanochemical procedure followed by a step of heat treatment at rather low temperature in furnace in air. The reaction was performed in solvent free conditions using triphenylphosphine (TPP) as a phosphorus source, cobalt acetate as a metal source and ammonium oxalate as a driving agent. The structural and morphological characteristics of the product was studied by several techniques including fourier transform infrared (FT-IR), X-ray diffraction (XRD), energy dispersive spectroscopic (EDS) and scanning electron microscopy (SEM). Two cubic phases of Co3O4 and CoP3 were observed in XRD pattern of the prepared product, which confirms the formation of a layered structure of Co3O4-CoP3 nanocomposite. Particle size distribution of the obtained product was determined using a Microstructure Measurement program and Minitab statistical software. Due to the simplicity, earth friendly and low-cost, this technique can be introduced as a promising route for synthesis of cobalt oxides and phosphides in nano scale with use of low energy in short time. |
