Abstract: A highly scalable process has been developed for stabilizing large quantities of the zeta-polymorph of V2O5, a metastable kinetically trapped phase, with high compositional and phase purity. The process utilizes a beta-Cux V2O5 precursor which is synthetized from solution using all-soluble precursors. The copper can be leached from this structure by a room temperature post-synthetic route to stabilize an empty tunnel framework entirely devoid of intercalating cations. The metastable ζ-V2O5 thus stabilized can be used as a monovalent-(Li, Na) or multivalent-(Mg, Ca, Al) ion battery cathode material.

Abstract: The Li-ion paradigm of battery technology is fundamentally constrained by the monovalency of the Li-ion. A straightforward solution is to transition to multivalent ion chemistries, with Mg2+ the most obvious candidate due to considerations of size and mass. Despite early interest, the realization of Mg batteries has faced myriad obstacles, including a sparse selection of cathode materials demonstrating the ability to reversibly insert divalent ions. Disclosed herein is evidence of reversible topochemical and electrochemical insertion of Mg2+ into a metastable one-dimensional polymorph of V2O5. Not only does ζ-V2O5 represent a rare addition to the pantheon of functional Mg battery cathode materials, but is also distinctive in exhibiting a combination of high stability, high specific capacity due to ion insertion, and moderately high operating voltage.

Abstract: The subject invention pertains to the synthesis and characterization of V2O5/CdE NW/QD heterostructures. The V2O5/CdE heterostructures are versatile new materials constructs for light harvesting, charge separation, and the photocatalytic production of solar fuels; polymorphism of V2O5 and compositional alloying of both components provides for a substantial design space for tuning of interfacial energy offsets. Also provided are a new class of type-II heterostructures composed of cadmium chalcogenide QDs (CdE where E=S, Se, or Te) and α-V2O5 nanowires (NWs). The synthesis and characterization of V2O5/CdE NW/QD heterostructures, prepared via successive ionic layer adsorption and reaction (SILAR) and linker-assisted assembly (LAA), the characterization of their photoinduced charge-transfer reactivity using transient absorption spectroscopy, and their performance in the photocatalytic reduction of protons to hydrogen are also disclosed.
