The development of alternative fuels from secure and sustainable resources is one of the greatest environmental and economic challenge society faces today. The development of methods for the conversion of inert and abundant, gaseous contaminants into energy-rich fuels and commodity chemicals requires the generation of catalysts that can perform a complex series of multi-electron and multi-proton transformations, facilitating the desired reactions selectively under ambient conditions. Research in the Matson Group focuses on using synthetic inorganic chemistry to address issues related to Energy Storage and Production. Toward accomplishing these goals, we are investigating the synthesis, characterization and reactivity of heterometallic polyoxovanadate-alkoxide clusters. These unique, multimetallic assemblies are generated in high yields via solvothermal reactions from simple molecular precursors. Notably, the Lindqvist, polyoxovanadate subunit possesses a high degree of redox flexibility, rendering it ideal for supporting multielectron transformations of energy-poor substrates. Additionally, these metal-oxide fragments have the capacity to serve as models for reduce metal-oxide surfaces, given their distinct ability to form oxygen-atom vacancies at single metal sites within the inorganic framework. Here, we present our results related to the activation of small molecules across these homo- and heterometallic polyoxovanadate-alkoxide clusters.
