| Abstract: | MoO2 microspheres were synthesized by a facile wet chemical method using the molybdenum trioxide as an inorganic precursor and paraphenylendiamine as a reducing agent and also a template, via a hydrothermal way. The as prepared product was characterized by XRD, SEM, TEM, DTA–TG, and IR. It was found that this product was composed by MoO2 nanoparticles encapsulated into the organic shell microspheres with diameters of 1–3 μm. The influence of the temperature on the crystallinity of the products was investigated. Optimal conditions founded were: reaction temperature: 220 °C, reaction time: 72 h and cooling time remains unchanged. The possible formation mechanism of MoO2 microspheres was also discussed. |
