Manganese oxide OMS-2 as an effective catalyst for total oxidation of ethyl acetate

OMS-2 Catalysts for Formaldehyde Oxidation: Effects of Ce and Pt on Structure and Performance of the Catalysts

“…Manganese oxides are well known to be active oxidation catalysts. Due to the mild surface acidity-basicity, porous structure and ion-exchange ability, OMS-2 materials recently are widely examined as catalysts in the oxidation of benzyl alcohol [1], ethanol [2], ethyl acetate [3], benzene [4], and 2-thiophenemethanol [5]. The porosity of OMS-2 arises because of peculiar edge sharing of 2 9 2 [MnO 6 ] octahedral chains to form one dimensional tunnel structure, with pores of the order of 0.46 nm.…”

Sphere-Shaped Mn3O4 Catalyst with Remarkable Low-Temperature Activity for Methyl–Ethyl–Ketone Combustion

“…15 Gandhe et al 16 showed that cryptomelane type manganese oxides, also called octahedral molecular sieve (OMS-2), had a highly efficient activity for the total oxidation of ethyl acetate, which was ascribed to the presence of Mn ) could promoted the mutual transformation between the electrons and formation of oxygen vacancy caused by charge mismatching, resulting in formation of chemisorbed oxygen. To develop cost-effective approach, the transition metal (e.g., manganese and iron) oxides catalysts may be potential and promising for MEK combustion.…”

Performance of Ti-pillared montmorillonite supported Fe catalysts for toluene oxidation: The effect of Fe on catalytic activity

“…The supported noble metal-based catalysts are considered as state-of-the-art catalysts, due to their higher activity at relatively low temperature as compared to metal oxides. But their disadvantages including high cost, easily sintering at high temperature, and susceptible poisoning by inorganic impurities (H 2 S, HCl, NH 3 , and alkali metals), prevent their application (Gandhe et al, 2007).…”
