Title: Polyoxovanadate-alkoxide clusters: Redox-active Scaffolds for the Multielectron Activation of Small Molecules
Abstract:  The development of alternative fuels from secure and sustainable resources is one the greatest environmental and economic challenge society faces today. To meet increased energy demands and mitigate rising atmospheric greenhouse gas levels, new carbon-neutral resources must be developed. The conversion of inert, abundant molecules, such as N2O and CO2, into chemical fuels (NH3 and CH3OH, respectively) represents an attractive solution, as energy is stored in chemical bonds of molecules that are easily transported as liquids. However, currently these fuels are produced through the activation of small molecules via heterogeneous processes conducted at extreme temperatures and pressures, requiring expensive, dedicated facilitiesResearch in the Matson Group focuses on using synthetic inorganic chemistry to address these 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 polyoxovanadate subunit possesses a high degree of redox flexibility, rendering it ideal for supporting multielectron transformations of inert, gaseous substrates. Herein, we present our results related to the activation of small molecules across heterometal-functionalized polyoxovanadate-alkoxide clusters.
