Visible-light-induced bactericidal activity of vanadium-pentoxide (V2O5)-loaded TiO2 nanoparticles.

The bactericidal activity of TiO(2) nanoparticles under visible light is very important in regards to its practical applications. In this paper, we synthesized vanadium-pentoxide-loaded TiO(2) nanoparticles (V(2)O(5)-TiO(2)) using a chemical vapor condensation method, followed by the impregnation method, and characterized its physicochemical properties through X-ray diffraction patterning, X-ray photoelectron spectroscopy analysis, Raman spectra analysis, and Fourier transform infrared analysis. In addition, the antibacterial activity of V(2)O(5)-TiO(2) nanoparticles against E.

Synthesis and photocatalytic activity of TiO2 nanoparticles prepared by chemical vapor condensation method with different precursor concentration and residence time.

Nanosized TiO(2) photocatalysts were synthesized using a chemical vapor condensation method under a range of synthesis conditions (precursor vapor concentration and residence time in a tubular electric furnace). X-ray diffraction showed that the prepared TiO(2) powders consisted mainly of anatase (>94%) with a small amount of rutile. The mean particle diameter from the Brunauer-Emmett-Teller surface area and transmission electron microscopy measurements ranged from 9.

Catalytic conversion of 1,2-dichlorobenzene using V2O5/TiO2 catalysts by a thermal decomposition process.

This study examined the catalytic oxidation of 1,2-dichlorobenzene on V(2)O(5)/TiO(2) nanoparticles. The V(2)O(5)/TiO(2) nanoparticles were synthesized by the thermal decomposition of vanadium oxytripropoxide and titanium tetraisopropoxide. The effects of the synthesis conditions, such as the synthesis temperature and precursor heating temperature, were investigated.

Oxygen-enriched air for co-incineration of organic sludges with municipal solid waste: a pilot plant experiment.

Pilot-plant experiments were performed to evaluate the effect of oxygen enrichment on the co-incineration of MSW and organic sludge from a wastewater treatment facility. Combustion chamber temperatures, stack gas concentrations, i.e.

Lipase mediated chiral resolution of 4-arylthio-2-butanol as an intermediate for beta-lactam antibiotics.

This paper deals with chiral enzymatic resolution of 4-arylthio-2-butanols by lipase to prepare potential intermediates of beta-lactam antibiotics. Among several lipases employed, lipase P type enzyme gave the highest ee value to prepare (R)-4-arylthio-2-butyl acetate. The enzymatic resolution of phenyl substituted alcohol (6a) using lipase P showed the highest ee value (99.
