The following thesis aims to address the constantly looming problem of indoor pollution. In fact, most of our time is spent in environments where the air exchange is not so sudden.This situation causes the accumulation of molecules harmful to our respiratory systems, leading to the onset of often lethal pathologies.Among the various abatement techniques, we focus on catalytic oxidation at low temperature.Manganese oxides are effective for abatement of substances such as volatile organic compounds.In the experimental part of the thesis, the different aspects related to the crystalline phases and catalytic properties of manganese oxides, mainly MnO_2 and 〖Mn〗_2 O_3 synthesized by Solution Combustion Synthesis (SCS) technique are, therefore, analysed and compared with the respective commercial ones.This technique is advantageous as it is simple and hasty and allows to obtain porous solids.
