Green decomposition of organic dyes using octahedral molecular sieve Manganese Oxide catalysts

King’ondu, Cecil K.; Sriskandakumar, Thamayanthy; Opembe, Naftali; Chen, Chun-Hu; Morey, Aimee; Suib, Steven L. (2009)

The catalytic degradation of organic dye (methylene blue, MB) has been studied using green oxidation methods (tertiary-butyl hydrogen peroxide, TBHP, as the oxidant with several doped mixed-valent and regular manganese ...
Microwave-assisted hydrothermal synthesis of Cryptomelane-type octahedral molecular sieves (OMS-2) and their catalytic studies

King’ondu, Cecil K.; Huang, Hui; Sithambaram, Shanthakumar; Chen, Chun-Hu; Xu, Linping; Iyer, Aparna; Garces, Hector F.; Suib, Steven L. (2010)

Manganese oxide octahedral molecular sieves (OMS) are important materials in environmental chemistry, electrochemistry, and heterogeneous catalysis. Here, a rapid process to prepare cryptomelane-type octahedral molecular ...
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 ...
Nanoscale manganese oxide octahedral molecular sieves (OMS-2) as efficient photocatalysts in 2-propanol oxidation

King’ondu, Cecil K.; Iyer, Aparna; Galindo, Hugo; Sithambaram, Shanthakumar; Chen, Chun-Hu; Suib, Steven L. (Elsevier, 2010-03)

Crystalline tunnel structure cryptomelane type manganese oxides (OMS-2) have been studied as photocatalysts for the selective oxidation of 2-propanol to acetone. The reaction is carried out with visible light irradiation ...
Preferential oxidation of CO in H2-rich feeds over mesoporous copper manganese oxides synthesized by a redox method

King’ondu, Cecil K.; Njagi, Eric C.; Genuino, Homer C.; Chen, Chun-Hu; Horvath, Dayton; Suib, Steven L. (Elsevier, 2011-06)

Mesoporous copper manganese oxides with high surface areas (>268 m2/g) were prepared using the redox method and tested in the preferential oxidation of CO. These materials were highly active and selective under typical ...
Single-step synthesis of Manganese Oxide octahedral molecular sieves with large pore sizes

King’ondu, Cecil K.; Huang, Hui; Chen, Chun-Hu; Xu, Linping; Genuino, Homer; Garcia-Martinez, Javier; Garces, Hector F.; Jin, Lei; Suib, Steven L. (2010)

A facile single-step method was developed for synthesizing todorokite-type manganese oxide octahedral molecular seieves (OMS-1) and 2 × 4 tunnel structured manganese oxide (OMS-5) materials. Selection of starting materials ...
