Water oxidation catalysis using Amorphous Manganese Oxides, Octahedral Molecular Sieves (OMS-2), and Octahedral Layered (OL-1) Manganese Oxide structures

King’ondu, Cecil K.; Iyer, Aparna; Del-Pilar, Joselyn; Kissel, Edward; Garces, Hector F.; Huang, Hui; El-Sawy, Abdelhamid M.; Dutta, Prabir K.; Suib, Steven L. (2012)

Water oxidation is the bottleneck in artificial photosynthetic systems that aim to split water into hydrogen and oxygen. However, water oxidation occurs readily in plants, catalyzed by the Mn4O4Ca manganese cluster. In ...
X-ray absorption spectroscopic study of a highly thermally stable Manganese Oxide Octahedral Molecular Sieve (oms-2) with high Oxygen reduction reaction activity

King’ondu, Cecil K.; El-Sawy, Abdelhamid M.; Kuo, Chung-Hao; Kriz, David A.; Guild, Curtis J.; Meng, Yongtao; Frueh, Samuel J.; Dharmarathna, Saminda; Ehrlich, Steven N.; Suib, Steven L. (American Chemical Society, 2014 Septe)

The development of catalysts with high thermal stability is receiving considerable attention. Here, we report manganese oxide octahedral molecular sieve (OMS-2) materials with remarkably high thermal stability, synthesized ...
