Coral-like nanostructured α-Mn2O3 nanaocrystals for catalytic combustion of methane: Part I. Preparation and characterization

Coral-like nanostructured α-Mn2O3 nanocrystals were prepared by oxidative decomposition of MnCO3, exhibiting tremendous activity in the catalytic combustion of methane. This prepared α-Mn2O3 nanocrystals showed ultra-high stability during reaction while the structure feature was unaffected. The ultra-stable structure of the α-Mn2O3 catalyst has been demonstrated by characterization of SEM, XPS, XRD, Raman spectroscopy. The performance of the α-Mn2O3 nanocrystals has proven reproducible and potentially to be an applied catalyst for methane combustion.
