Cryptomelane-type manganese oxide (OMS-2) was synthesized successfully using urea hydrogen peroxide (urea.H2O2) as the reductant in an acidic buffer solution As-prepared crystalline material was fully characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller method (BET), XPS, SEM (SEM) and high resolution transition electron microscopy(HRTEM). The results demonstrate that OMS-2 has nanofiber with short nanorod morphologies, very rich oxygen vacancy defected and more exposed crystal facets compared with ones synthesized with other H2O2-containing reductants. These unique properties made nanostructural OMS-2 an excellent heterogeneous catalyst in aerobic oxidation reactions, such as selective oxidation of mercaptan and oxygenation of alkylarenes.
