| Abstract:
In this study, zinc silicate (Zn2SiO4 ) nanostructured particles have been synthesized by sol-gel process using zinc nitrate and tetra ethyl oxysilane (TEOS) precursors. Results have been shown information of amorphous and crystalline structures during increasing of calcination temperature. Structural evolutions of gel and calcined gel in different temperatures have been investigated using DTA and XRD analyses, respectively. Due to XRD analysis of calcined samples in 800 and 900o C, and Scherrer equation has been obtained grain size 13 and 27 nm, respectively. Also, DTA analysis of precursors has been shown endothermic reaction of solvents evaporation and decomposition organic phases, and exothermic reaction of Zn2SiO4 composition. Furthermore, SEM observations showed negligible difference between powder size of amorphous precursors and crystalline Zn2SiO4 were between 50 and 400 nm. Moreover, UV-visible spectroscopy analysis for photocatalyst properties has been shown acceptable results.
