Commercialization of cryptomelane-type manganese oxide (OMS-2) nanowire paper oil sorbent
Cryptomelane-type Manganese oxide (OMS-2, a group of Octahedral Molecular Sieves) nanowire paper exhibits interesting properties: reversible wettability, oleophilic while being hydrophobic, and high thermal stability. These properties open up possible markets for commercialization. This thesis …

MANGANESE OXIDE AS A NEW CATHODE CATALYST IN MICROBIAL FUEL CELLS (MFCs)
… a cryptomelane-type octahedral molecular sieve (OMS-2) structure to replace platinum as a cathode catalyst in microbial fuel cells (MFCs). Undoped (ud-OSM-2) and three catalysts doped with cobalt (Co-OMS-2), copper (Cu-OMS-2), and cerium (Ce-OMS-2) to enhance their catalytic performances were …

Understanding Heterogenous Catalysis on Zeolites and Manganese Oxides
… conducted on birnessite (OL) and cryptomelane (OMS-2). Using acetaldehyde as the substrate molecule, the mechanism on Birnessite, is proposed to proceed via a solvent assisted Eley-Rideal mechanism with molecular hydrogen in the liquid phase. Birnessite has no available adsorption site without …
