The work presents a study of the formation of manganese oxide aerogels in the process of thermal decomposition of manganese carbonyls in oxygen-enriched supercritical CO2 at different temperatures. The morphology of the aerogels was studied by means of electron microscopy; the porous structure was investigated through the analysis of low-temperature nitrogen adsorption/desorption isotherms. The process was observed in an optical high-pressure view-cell.
