Kraft lignin is efficiently depolymerized under benign conditions into value-added aromatics and high-quality bio-oil using a facile vanadium–copper catalyst system.

A study on the application of V(2)O(5)/WO(3)/TiO(2) (VWT) as the sensitive material for resistive-type SO(2) sensor was conducted, based on the fact that VWT is a well-known catalyst material for good selective catalytic nitrogen oxide reduction with a proven excellent durability in exhaust gases. The sensors fabricated in this study are planar ones with interdigitated electrodes of Au or Pt. T...

Vanadium-based catalysts are considered the most promising materials to replace cobalt-based for activation of peroxymonosulfate (PMS) degrade organic pollutants. However, these traditional vanadium species easily leak out metal ions that can affect environment, even though is much less than cobalt. Compared other vanadium-based catalysts, e.g., V2O3, fluorinated V2AlC shows a high and constant...

During the year of 2014, advances in vanadium science were celebrated at the International Vanadium Symposium in Italy in July and at the 248th American Chemical Societymeeting in San Francisco in August. The vanadium symposium entitled “V9, 9th International Vanadium Symposium” was held for the first time in Italy, organized by the Chairwoman of the Vanadium Society Prof. Valeria Conte and Pro...

The electrocatalysis of the oxygen reduction reaction (ORR) on carbon supportedPt-V (1:1) catalyst in polymer electrolyte fuel cells (PEFC) was investigated. Atan oxygen pressure of one atm an enhanced electrocatalytic property of Pt-V/Ccompared with Pt/C is revealed. These results indicate the occurrence of adifferent electrocatalytic mechanism for the ORR on Pt/C and Pt-V/C. Anincrease of mas...

Postmortem analysis of a CoV2O4 catalyst for oxygen evolution reveals the active species is likely vanadium-free amorphous cobalt oxide.

Oxo- and imido-vanadium(V) metal complexes supported by bis(phenolate)-functionalized N-heterocyclic carbene (NHC) ligands were synthesized structurally identified. In the presence of [(Ph3P)2N]Cl ([PPN]Cl), saturated NHC oxo-vanadium showed activity in coupling CO2 cyclohexene oxide (CHO) into cis-cyclohexene carbonate (cis-CHC). More importantly, complex bearing less electron-donating benzann...
