Broadband enhancement of devices and microsystems for light harvesting and photocatalysis
(Springer, 2020)
Plasmonic materials, stochastically roughened, can provide localized field enhancement under optical irradiation (light trapping). The use of plasmonic materials in semiconductor photocatalists also leads to drastic ...
CdS particles modified TiO2 coatings formed by plasma electrolytic oxidation with enhanced photocatalytic activity
(Elsevier, 2018)
CdS particles modified anatase TiO2 photocatalysts were formed on titanium substrate by plasma electrolytic oxidation for 2 min in supporting electrolyte (10 g/L Na-3 center dot PO4 center dot 12H(2)O) with addition of CdS ...
Hybrid visible-light responsive Al2O3 particles
(Elsevier, 2017)
Detailed study of Al2O3, an insulator with the band gap of about 8.7 eV, and its different organic/inorganic charge transfer complexes with visible-light photo activity is presented. In particular, prepared Al2O3 particles ...
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 ...

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 ...
Quantitative structure-activity relationship analysis of substituted arylazo pyridone dyes in photocatalytic system: Experimental and theoretical study
(Elsevier, 2016)
A series of arylazo pyridone dyes was synthesized by changing the type of the substituent group in the diazo moiety, ranging from strong electron-donating to strong electron-withdrawing groups. The structural and electronic ...
