Vanadium Extraction Opportunities in Alumina Production and Vanadium Complex Study in Organic Phase

Alumina-supported vanadium nanoparticles: structural characterization and CO adsorption properties.

Alumina-supported vanadium particles were prepared under ultrahigh vacuum (UHV) conditions and characterized with respect to their structural and CO adsorption properties. As supporting oxide, we used a thin, well-ordered alumina film grown on NiAl(110). This allows the application of scanning tunneling microscopy (STM), infrared reflection-absorption spectroscopy (IRAS), and X-ray photoelectro...

Thermally Stable Solution Processed Vanadium Oxide as a Hole Extraction Layer in Organic Solar Cells

Low-temperature solution-processable vanadium oxide (V₂Ox) thin films have been employed as hole extraction layers (HELs) in polymer bulk heterojunction solar cells. V₂Ox films were fabricated in air by spin-coating vanadium(V) oxytriisopropoxide (s-V₂Ox) at room temperature without the need for further thermal annealing. The deposited vanadium(V) oxytriisopropoxide film undergoes hydrolysis in...

Resonance Raman spectroscopic study of alumina-supported vanadium oxide catalysts with 220 and 287 nm excitation.

We present detailed resonance Raman spectroscopic results excited at 220 and 287 nm for alumina-supported VO(x) catalysts. The anharmonic constant, harmonic wavenumber, anharmonic force constant, bond dissociation energy, and bond length change in the excited state for double bonded VO and single bonded V-O were obtained from fundamental and overtone frequencies. Totally symmetric and nontotall...
