| Redox-active transition metal oxides have shown significant promise for application in the contexts of catalysts, batteries, photovoltaics, and electrochromics. Both nanostructure and porosity are important parameters that influence performance parameters such as mass transport, ion storage capacity, redox reversibility, and stability. This talk will focus on novel approaches for preparing mixed metal oxides to selectively regulate composition, porosity and nanostructure. Furthermore, the preparation of new electrode materials also requires creation of new analytical tools for their characterization. As such, we will also describe a newly developed spectroscopic ellipsometry technique to directly assess structural and compositional characteristics of metal oxide electrodes such as thickness, refractive index, compositional heterogeneity, pore size, pore distribution, and pore volume. |
