Preparation and photocatalyic properties of TiO2-P25 film prepared by spray pyrolysis method
(Elsevier, 2013)
TiO2 films were synthesized by immobilization of Degussa P25 powders on stainless steel support by spray pyrolysis technique. After preparation, the films were annealed at different temperatures in order to obtain materials ...
Structure-activity relationship of nanosized porous PEG-modified TiO2 powders in degradation of organic pollutants
(Elsevier, 2015)
This study aims to gain insights in structure-activity relationship of TiO2 photocatalysts. For this purpose photocatalysts were synthesized via classical sol-gel method using titanium isopropoxide as a precursor and ...
The photocatalytic performance of silver halides - Silver carbonate heterostructures
(Elsevier Science Sa, Lausanne, 2017)
The synthesized rod-like Ag2CO3 particles (2-4 x 0.3-0.6 mu m, length x diameter) served as a precursor for preparation of the AgX/Ag2CO3 (X = CI, I) composites by ion exchange method. The various microstructural (X-ray ...
Metal layers with subwavelength texturing for broadband enhancement of photocatalytic processes in microreactors
(Springer, 2018)
In this paper we joined plasmonics and microreactors for photocatalytic optofluidic devices. To this purpose we consider the use of subwavelength texturing of plasmonic films applied to microreactor channel bottom to ensure ...
Influence of annealing temperature on structural, optical and photocatalytic properties of TiO2-CeO2 nanopowders
(Elsevier Sci Ltd, Oxford, 2019)
TiO2-CeO2 nanopowders were synthesised by a ball-milling process and then annealed at temperatures from 500 degrees to 800 degrees C. X-ray diffraction and diffuse reflectance spectra were used in combination with temperature ...
MgO/ZnO coatings formed on magnesium alloy AZ31 by plasma electrolytic oxidation: Structural, photoluminescence and photocatalytic investigation
(Elsevier, 2017)
This paper presents the results of our recent investigation of MgO/ZnO coatings formed on AZ31 magnesium alloy by plasma electrolytic oxidation in phosphate-based alkaline electrolyte with varying concentration of ZnO ...
Zirconium dioxide nanopowders with incorporated Si4+ ions as efficient photocatalyst for degradation of trichlorophenol using simulated solar light.
(Amsterdam : Elsevier Science BV, 2016)
We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporated Si4+ ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powders were annealed at 600 ...
Structural, optical and photodegradation properties of pure and Fe-doped titania nanoparticles probed using simulated Solar light
(Elsevier Sci Ltd, Oxford, 2016)
We report the successful, low temperature synthesis of pure and Fe-doped titania nanoparticle (NP) powders, using organic Ti- and Fe-precursors. The properties of the synthesized titania based materials were obtained using ...
A Synergy of ZnO and ZnWO4 in Composite Nanostructures Deduced from Optical Properties and Photocatalysis
(Springer/Plenum Publishers, New York, 2013)
ZnO/ZnWO4 composite rod-like nanoparticles were synthesized by low-temperature soft solution method at 95 A degrees C with different reaction times (1-120 h), in the presence of non-ionic copolymer surfactant Pluronic F68. ...
Superior photocatalytic properties of carbonized PANI/TiO2 nanocomposites
(Elsevier, 2017)
A simple bottom-up method for the preparation of novel and very efficient photocatalytic nanocomposite system based on carbonized form of polyaniline (PANI) and colloidal TiO2 nanocrystals has been developed. The carbonized ...
