The study of zirconium vanadate as a cathode material for lithium ion batteries

The carbon content in the electrode is not the only factor that determines the internal resistance. The high capacity of lithium ion batteries is related to high conductivity. The lattice is stable (expect for shrinkage) when Li ions insert into ZVO.

Microwave Derived Nano Sized Zirconium Vanadate as an Adsorbent for Heavy Metal Ions

Bimetallic metal oxide nanomaterials are synthesized by microwave combustion route encourage to the synthetic chemists because of its simplicity. Microwave burning of single-phase oxide materials with polymer as fuel to form its multiphase nanomaterials. Nanosized Zirconium vanadate (ZrV2O7) material is prepared by self-propagating combustion methods using a polymer as a fuel. Zirconium oxide (ZrO2) and vanadium pentoxide (V2O5) with polyvinyl alcohol were ignited in an open atmosphere and complete burning in a microwave oven for about 15 minutes to form a zirconium vanadate sample. Adsorption study of heavy metal ions like lead and mercury ions on the prepared sample is well studied. The structure of as-prepared ZrV2O7 and its adsorbed sample was well studied by employing a powder X-ray diffraction (XRD) tool. The morphology of as-prepared ZrV2O7 and adsorbed sample material was studied by Scanning Electron Micrograph (SEM) tool. Fourier Transform Infrared (FTIR) spectral study was undertaken to know the bonding in the prepared zirconium vanadate nanomaterials. Further, the adsorption study of heavy metal ions on the ZrV2O7 sample is also undertaken at room temperature.

Kinetics and Mechanism of Slurry Phase Air Oxidation of Benzyl Alcohol over Zirconium Vanadate Catalyst

The kinetics of slurry phase air oxidation of benzyl alcohol to benzaldehyde over zirconium vanadate catalyst is reported in this study. Initial rates for the formation of product were determined by varying the partial pressures of the reactants. The data collected were found to satisfy a rate law: R = [(k1PBk2Po)/(k1PB + k2Po)]. The study suggests that reaction follows a Mars-Van Krevelen type of redox mechanism.
