Recent Advances in Nanostructured Vanadium Oxides and Composites for Energy Conversion

Abstract

Vanadium oxides are known for their multioxidation states and diverse crystalline structures. Owing to their excellent interactions with molecules or ions, outstanding catalytic activities, and/or strong electron–electron correlations, nanostructured vanadium oxides have been extensively studied for energy conversion in the recent years. Here is a review of the recent advances in the development of nanostructured vanadium oxides and their applications. The synthesis strategies and structural properties of various vanadium oxide nanostructures, including vanadium dioxide (VO2), vanadium pentoxide (V2O5), and others, are summarized. The applications of vanadium oxides in energy conversion are discussed, focusing on three important types of energy sources: chemical energy (LIBs, pseudocapacitors and fuel cells), solar energy (photovoltaics and photocatalytic hydrogen evolutions), and heat (thermoelectric generation). Finally, conclusion with our remarks on the prospects of nanostructured vanadium oxides in energy conversion are provided.

Vanadium‐Based Nanomaterials: A Promising Family for Emerging Metal‐Ion Batteries

“…Whittingham group has performed a lot of pioneering works on vanadium‐based materials for LIBs, and has also made important reviews before 2010 . In recent years, we also note that several reviews that focused on the Li + storage properties of vanadium‐based nanomaterials or specific one vanadium‐based compound for energy related applications have been published . However, a review article which comprehensively summarizes the vanadium‐based nanomaterials family, and focuses on the special merits of their applications for emerging metal‐ion batteries is still lacking.…”

Vanadium Doped Nickel Phosphide Nanosheets Self‐Assembled Microspheres as a High‐Efficiency Oxygen Evolution Catalyst

“…However, it is also noted that the catalytic activity of monometallic Ni 2 P is limited to the few types of composition and structure . On the other hand, vanadium (V) is a kind of rich element in the earth‘s crust . Due to its various valence states, vanadium‐modified compounds exhibit excellent electrochemical properties.…”

Development of VO2‐Nanoparticle‐Based Metal–Insulator Transition Electronic Ink

“…The MIT temperature of VO 2 (M) can also be further reduced by doping [14] and by varying the particle sizes. [22,23] Due to the exciting applications mentioned above, considerable effort has been devoted to producing VO 2 (M) in the form of a thin film, primarily with a dry vapor process using chemical vapor deposition, [24] sputtering, [25] metalorganic molecular beam epitaxy deposition, [26] pulsed laser deposition, [27,28] e-beam evaporation, [29] and by electric field inducing ions migration.
