to improve the photo-catalytic degradation of salicylic acid, we reported the fabrication of ordered tio2 nanotube arrays by a simple and effective two-step anodization method and then these tio2 nanotubes treated in a methanol solution under uv light irradiation. the tio2 nanotubes prepared in the two-step anodization process showed better photo-catalytic activity than tio2 nanotubes prepared ...

tio2 photo catalyst was prepared in presence of nano sio2 and hydroxy propyl cellulose (hpc) by sol gel method with titanium tetra isopropoxide (ttip) as titanium precursor. additional effect of hpc in preparation of nano catalyst, and photo catalyst properties measured and characterized by ft-ir, ft-raman and sem. the catalyst size and structural properties of the film were determined by .-ray...

ZnO and ZrO2 photo catalysts were synthesized by sol-gel auto combustion method. The products were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and ZrO2 was obtained 44 and 51 nm, respectively. Also, photo catalytic degrada...

In this research, Zn2SiO4 as a support and MnFe2O4 as a main photo-catalyst were individually syn-thesized and MnFe2O4 was fixed on Zn2SiO4 with solid state dispersion method. MnFe2O4 nano pho-to-catalyst was synthesized by co-precipitation method and reflux condition for 12 hours at 85°C in the presence of urea. For identification of catalysts Fourier-transform infrared (FTIR) sp...
