The transition to a more sustainable energy economy will require new, better performing materials for the conversion of renewable energy sources into fuels and the storage of these fuels. Our research focuses on controlling the structure and composition at the nanometer scale as a strategy to produce materials with extraordinary properties. We discovered that nanostructured nitrides and carbides possess high capacitances in aqueous electrolytes. The basis for these high capacitances appears to be a pseudocapacitive charge storage mechanism. Using electrochemical and in situ x-ray absorption spectroscopic methods we were able to define key aspects of the charge storage mechanism for early transition metal nitrides and carbides.
