Direct sonochemical synthesis of Manganese Octahedral Molecular Sieve (OMS-2) Nanomaterials using cosolvent systems, their characterization, and catalytic applications

King’ondu, Cecil K.; Dharmarathna, Saminda; Pedrick, Wyatt; Pahalagedara, Lakshitha; Suib, Steven L. (2012)

A rapid, direct sonochemical method has successfully been developed to synthesize cryptomelane-type manganese octahedral molecular sieve (OMS-2) materials. Very high surface area of 288 ± 1 m2/g and small particle sizes ...
Manganese octahedral molecular sieve (OMS-2) catalysts for selective aerobic oxidation of thiols to disulfides

King’ondu, Cecil K.; Dharmarathna, Saminda; Pahalagedara, Lakshitha; Kuo, Chung-Hao; Zhang, Yashan; Suib, Steven L. (Elsevier, 2014-04)

Selective aerobic oxidation of thiols to disulfides without any over oxidized products is studied using cryptomelane type manganese oxides (K-OMS-2) with a tunnel structure as catalysts. Using K-OMS-2 prepared by different ...
