ABSTRACT

Rice husk (RH) and RH ash (RHA) are good sources of low-cost adsorbents. This work presented the results of the study on preparation and characterization of tin oxide – silica nanocomposite synthesized from RHA using sol gel method. Nanosilica (SiO2) was extracted by calcination of HCl treated RHA at 700°C for 6 h. The physicochemical properties SiO2, SnO2 and their nanocomposite (SnO2–SiO2) were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction spectrometer, and UV-Vis spectrophotometer (UV). Surface areas and crystallite size of SiO2, SnO2 and their nanocomposite (SnO2–SiO2) were calculated using Sear’s method and Debye Scherrer equation. Characteristic results revealed that SiO2, SnO2, and their nanocomposite (SnO2–SiO2) were successfully synthesized from RHA. Thus, the synthesized
nanosilica SiO2, SnO2, and their nanocomposite (SnO2–SiO2) can be used for application in dye degradation of wastewater treatments with recyclable nanocomposite.
