Preparation and characterization of coral-like nanostructured alpha-Mn2O3 catalyst for catalytic combustion of methane

摘要

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