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 ...
Light-assisted synthesis of Metal Oxide heirarchical structures and their catalytic applications

King’ondu, Cecil K.; Iyer, Aparna; Njagi, Eric C.; Opembe, Naftali; Genuino, Homer; Huang, Hui; Ristau, Roger A.; Suib, Steven L. (2011)

Short reaction times and morphology control in the synthesis of inorganic materials under nonthermal conditions remain a challenge. Herein we report a rapid, self-templating, and nonthermal method based on ultraviolet light ...
Manganese Oxide Octahedral Molecular Sieves (OMS-2) multiple framework substitutions: A new route to OMS-2 particle size and morphology control

King’ondu, Cecil K.; Opembe, Naftali; Chen, Chun-hu; Ngala, Katana; Huang, Hui; Iyer, Aparna; Garcés, Hector F.; Suib, Steven L. (Wiley, 2011-01)

Self-assembled multidoped cryptomelane hollow microspheres with ultrafine particles in the size range of 4–6 nm, and with a very high surface area of 380 m2 g−1 have been synthesized. The particle size, morphology, and the ...
