Co₃O₄ nanocubes were synthesized via a simple hydrothermal method. X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) analysis revealed that the product was cubic single crystal Co₃O₄, with the width of several ten nanometers to several hundred nanometers. The influence of reaction temperature and the amount of dispersant on the size and morphology of the as-obtained Co₃O₄ were investigated. On the basis of condition-dependent experiments, a possible aggregate-dissolution-recrystallization growth mechanism was proposed to explain the formation process of the Co₃O₄ nanocubes. The catalytic activity characterization showed that the as-prepared Co₃O₄ nanocubes can catalyze the thermal decomposition of ammonium perchlorate (AP) effectively.

Abstract

Co₃O₄ nanocubes were synthesized via a simple hydrothermal method. X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM) analysis revealed that the product was cubic single crystal Co₃O₄, with the width of several ten nanometers to several hundred nanometers. The influence of reaction temperature and the amount of dispersant on the size and morphology of the as-obtained Co₃O₄ were investigated. On the basis of condition-dependent experiments, a possible aggregate-dissolution-recrystallization growth mechanism was proposed to explain the formation process of the Co₃O₄ nanocubes. The catalytic activity characterization showed that the as-prepared Co₃O₄ nanocubes can catalyze the thermal decomposition of ammonium perchlorate (AP) effectively.
