Abstract

Nano silica (SiO2) has an extensive range of products from manufacturing to
scientific. The Sol-gel technique in the field of material science is receiving
worldwide interest because of its versatility for synthesizing silica nanoparticles.
It provides a controlled composition of organic/inorganic hybrid material
because of its unique and low-cost processing. The silica nanoparticles
were prepared by the sol-gel method via two different routes first is a basecatalyzed
hydrolysis reaction and the second is an acid-catalyzed hydrolysis
reaction. The prepared silica nanoparticles were characterized by techniques
Particle size analysis, Zeta potential, Fourier transform Infrared spectroscopy
(FTIR), and X-Ray diffraction spectroscopy (XRD). Particle size analysis
showed the nano range of particle and zeta potential proves the stability of
prepared sols. Observed peaks from IR spectra are confirming the presence of
a silica network. The amorphous silica was verified by the absence of sharp peaks and the presence of a broad peak at a 2 angle of 23.8 for the XRD
analysis structure in the produced NPs.
