Abstract


This paper presents a promising route for the synthesis of silica nanoparticles (SiO2) with diameter in range below 5nm. SiO2 were successfully synthesized by sol-gel method.The precursor solutions were made by mixing Silicon Tetrachloride (SiCl4), TRITON X-100 LR (t-octylphenoxypolyethoxyethanol) and sodium hydroxide (NaOH) in the molar ratio of 1: 1: 2. The powder catalyst is thermally treated at 120oc temperatures; the detailed Microscopic and Spectroscopic characterizations of core/shell structure (SiO2) were conducted by using Ultraviolet Spectroscopy (UV), Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD). The degradation of Congo red dye takes place in the presence of sunlight or with photo-catalytic reactor. High catalytic activity and ease of recovery from the reaction mixture using filtration, and several reuse times without significant losses in performance are additional eco-friendly attributes of this catalytic system
