Hierarchically porous Mn 3 O 4 has been synthesized via a facile solution combustion synthesis using Mn(NO 3 ) 2 · 4H 2 O as an oxidizer and ethylene glycolc (EG) as a fuel. The thermal analysis indicated that the combustion reaction can be initiated at a low temperature (126–140 °C). The obtained Mn 3 O 4 appeared as a hierarchical network with well‐connected poroes. At room temperature, the porous Mn 3 O 4 was found to be highly effective for catalytic degradation of methyl orange (MO) in the presence of acid.
