Abstract

Coral-like nanostructured α-Mn₂O₃ has been prepared by oxidative decomposition of MnCO₃. This catalyst exhibited tremendous reactivity during the catalytic combustion of methane compared to the commercial α-Mn₂O₃. It also showed ultrahigh stability during methane oxidation while the structure features were unaffected. The ultra stable structure of α-Mn₂O₃ catalyst during reaction has been demonstrated by the characterization of SEM, XRD, and Raman spectroscopy. The performance of the α-Mn₂O₃ as-prepared has proven to be reproducible and potentially can be applied as a catalyst for methane combustion.
