Abstract
The hydro(solvo)thermal synthesis method was used to successfully synthesize bare silica aerogels and nano- and microparticle-embedded silica aerogels containing SiO2 and carbon microparticles in this study. New groups were added to these structures through modification. In the study, first, the effect of the variables was systematically examined to determine the optimum conditions. The most suitable recipe for silica aerogel was created. SiO2 and CP particles were synthesized, and modified silica aerogels were prepared with these particles and agents containing amine. For the characterization of synthesized silica aerogel, particles (SiO2, CP) and particle-embedded silica aerogels, TGA, SEM, DLS and BET-BJH techniques were used. These structures were used as adsorbent in environmental applications such as removing organic pollutants like 4-nitro phenol, methylene blue, Victoria blue, bromophenol blue etc. from aqueous media. In this environmental application, the adsorption capacity (mg/g) was determined by using UV-vis spectroscopy. The prepared structures are good adsorbents, and the adsorption capacity can be increased 18-fold with modification.
