نویسندگان
چکیده
SiO 2 /Bi WO 6 photocatalyst with Si/Bi/W=1:2:1 molar ratio was obtained by the sol-gel method from bismuth nitrate, sodium tungstate and biogenic silica rice husk biomass followed calcination. Bi used as a control sample. FT-IR, SEM, XRD, EDXRF, UV-Vis methods were to systematically characterize as-obtained materials. Photodegradation of Indigo Carmine in exposure UV, sunlight xenon light studied evaluate their photocatalytic activities presence . It shown that degradation degree under action UV irradiation reaches 36% 14%, respectively. The sample is stable during studies.

Characterization of Structural, Optical and Hydrophilicity properties of TiO2 Nano-Powder Synthesized by Sol-Gel Method
In this paper, titanium dioxide nano-particles were synthesized by sol-gel method in acidic atmosphere. The microstructure, morphology, optical band gap, and hydrophilicity of the sample were studied. Optical band gap of titanium dioxide was probed via Diffuse Reflectance Spectra (DRS) and contact angle (CA) was measured to investigate surface activity. XRD analysis was used to study crys...

متن کاملModification of Silica surface by Titanium sol synthesis and characterization
Hydrophobic silica titanium nanoparticles (STNPs) were successfully synthesized by the sol-gel process using liquid modification. Fourier transform infrared (FTIR) and X-ray fluorescence (XRF) studies were demonstrated the attachment of titanium on the silica surface. Titanium content enhanced the agglomeration of particles as shown in topography results. The N2 adsorption-desorption followed T...
