J Am Chem Soc. 2016 Dec 28. doi: 10.1021/jacs.6b10657. [Epub ahead of print]The development of active water oxidation catalysts is critical to achieve high efficiency in overall water splitting. Recently, sub-10-nm-sized monodispersed partially-oxidized manganese oxide nanoparticles were shown to exhibit not only superior catalytic performance for oxygen evolution, but also unique electrokinetics, compared to their bulk counterparts. In the present work, the water-oxidizing mechanism of partially-oxidized MnO nanoparticles was investigated using integrated in-situ spectroscopic and electrokinetic analyses. Read More
