Revisiting the Decomposition Process of Tetrahydrate Co(II) Acetate: A Sample’s Journey through Temperature

Cobalt oxides, CoO and Co3O4, were obtained from Co (II) acetate tetrahydrate. The thermal decomposition pathway of the starting product was followed by combining thermogravimetric analysis in situ X-ray thermodiffraction. Under a nitrogen atmosphere, cobalt monoxide with Zn-blende rocksalt polymorphs could be almost as single phases at 330 400 °C, respectively. In addition to these oxyacetate, Co3O(CH3COO)4, stabilized an intermediate phase. air Co3O4 (spinel structure type) only final product. involved this process characterized scanning transmission electron microscopy (SEM TEM, respectively).
