Manganese oxides synthesized via microwave-assisted hydrothermal method: phase evolution and structure refinement

“…This technique has gained notoriety in recent decades and is now widely used in the synthesis of advanced ceramics [29,30]. Particularly for manganese oxides, it is likely that the first synthesis using the MAH method occurred in 2006, where APTE et al [31] obtained the α-MnO 2 and Mn 3 O 4 phases.…”

Manganese oxides synthesized via microwave-assisted hydrothermal method: phase evolution and structure refinement

“…Therefore, it becomes necessary to explore other synthesis routes that allow greater control of the material's microstructure and morphology. For hausmannite, for example, several methods can be used to control the morphology of the nal product, such as chemical reduction, co-precipitation, auto-combustion, sol-gel, solid state reaction, carburization or through the conventional hydrothermal method [20][21][22][23][24][25]. Additionally, the Microwave-Assisted Hydrothermal (MAH) method is an alternative way to synthesize manganese oxides, making it possible to obtain a nal material with high crystallinity, reasonable control of particle size and morphology, in addition to be environmentally friendly (the synthesis medium is not organic) and energetically viable (short synthesis times at low temperatures) [26].…”
