The main aim of the presentation is to demonstrate a novel method of preparing manganese oxide nanoparticles from organic precursor using supercritical CO 2 . In our approach, we dissolve metalorganic precursor in supercritical CO 2 and then thermally destroy organic phase in sc CO 2 media, with admixed O 2 , to produce oxide nanoparticles. As a result of the conducted experiments, highly dispersed manganese oxides in a β-MnO 2 phase with high specific surface and monodispersity degree were synthesized. In addition, pronounced electrocatalytic activity of the resulting material was found.
