Efficient oxidation of 2,3,6-trimethyl phenol using non-exchanged and H+ exchanged Manganese Oxide Octahedral Molecular Sieves (K-OMS-2 and H–K-OMS-2) as catalysts

King’ondu, Cecil K.; Opembe, Naftali N.; Suib, Steven L. (Springer Verlag, 2012)

A new and efficient oxidation process of 2,3,6- trimethyl phenol to 2,3,6-trimethyl benzoquinone (TMQ) is reported forthwith using non-exchanged and H?-exchanged manganese oxide octahedral molecular sieves (K-OMS-2 and ...
Microwave-assisted synthesis of Manganese Oxide Octahedral Molecular Sieve (OMS-2) nanomaterials under continuous flow conditions

King’ondu, Cecil K.; Opembe, Naftali N.; Espinal, Anais E.; Chen, Chun-Hu; Nyutu, Edward K.; Crisostomo, Vincent M.; Suib, Steven L. (2010)

A continuous flow microwave method has been developed for the synthesis of cryptomelane-type K-OMS-2 nanomaterials in a mixed aqueous−organic solvent system. The system is ideal for multikilogram synthesis of K-OMS-2 ...
Nonthermal synthesis of three-dimensional metal oxide structures under continuous-flow conditions and their catalytic applications

King’ondu, Cecil K.; Opembe, Naftali N.; Genuino, Homer C.; Garces, Hector F.; Njagi, Eric C.; Iyer, Aparna; Huang, Hui; Dharmarathna, Saminda; Suib, Steven L. (2011)

Continuous-flow synthesis of one-dimensional (1D) metal oxide nanostructures and/or their integration into hierarchical structures under nonthermal conditions is still a challenge. In this work, a nonthermal, continuous-flow ...
Vapor-phase oxidation of Benzyl Alcohol using Manganese Oxide Octahedral Molecular Sieves (OMS-2)

King’ondu, Cecil K.; Opembe, Naftali N.; Guild, Curtis; Nelson, Nicholas C.; Slowing, Igor I.; Suib, Steven L. (American Chemical Society, 2014, Nove)

Vapor-phase selective oxidation of benzyl alcohol has been accomplished using cryptomelane-type manganese oxide octahedral molecular sieve (OMS-2) catalysts. A conversion of 92% and a selectivity to benzaldehyde of 99% ...
