Enhanced photocatalytic activity of silver vanadate nanobelts in concentrated sunlight delivered through optical fiber bundle coupled with solar concentrator
(Springer, 2020-02-01)
To date, sunlight driven photocatalytic process for wastewater treatment is a great challenge. Herein, the photocatalytic methylene blue (MB) dye degradation activity of silver vanadate nanobelts has been enhanced using ...
Quantitative determination of the number of surface active sites and the turnover frequency for methanol oxidation over bulk metal vanadates
(Elsevier Science, 2003-02)
The present work investigates the number and nature of the surface active sites, selectivity and turnover frequency towards methanol selective oxidation of a series of bulk metal vanadates. The catalysts were synthesized ...
Infrared to visible up-conversion in biocellulose yttrium vanadate nanoparticle composite membranes. Demonstration of chloroaluminum phthalocyanine light emission under up-converted light excitation
(2014)
YVO4:(Yb3 +–Er3 +/Ho3 +) nanoparticles were incorporated in biocellulose membranes obtained from Gluconacetobacter xylinus. Materials present the property of converting near-infrared (NIR) into higher-energy visible light. ...
Nanostructured silver vanadate as a promising antibacterial additive to water-based paints
(Elsevier Science BvAmsterdamHolanda, 2012)
Simple and fast spectrophotometric determination of H2O2 in photo-Fenton reactions using metavanadate
(Elsevier B.V., 2005-03-31)
This work proposes a spectrophotometric method for the determination of hydrogen peroxide during photodegradation reactions. The method is based on the reaction of H2O2 with amonium metavanadate in acidic medium, which ...
