Mesoporous polyethylene glycol (PEG)/silica and carbon black (CB)/silica xerogel composites were prepared by the solgel method as an adsorbent for CO2 adsorption. The CO2 adsorption process was carried out under pure CO2 atmosphere at room temperature in addition to ambient air. The xerogel composites with high surface area and pore volume showed better CO2 adsorption capacity than the pure silica xerogel. After modifying samples with propylene diamine using the wet impregnation method, an increase in CO2 adsorption capacity was observed for the samples except CB/silica xerogel composite.

Nickel ferrite magnetic nanoparticles (NiFe2O4MNPs) were prepared via the autocombustion assisted solgel method. The efficient catalyst was investigated by FT-IR, XRD, ICP, SEM, and TEM techniques. A one-pot, three-component reaction is reported for the synthesis of substituted 4H -chromenes in the presence of NiFe2O4 MNPs as a reusable catalyst in a green solvent at 40◦C under clean, efficient, and mild conditions. Furthermore, selected products were characterized by FT-IR, 1H NMR, and 13C NMR. The single-crystal X-ray analysis of product 4u was also conclusively confirmed.

An Al2O3 overcoated TiO2:N layer was synthesized using the solgel method. XRD, SEM and UV-vis measurements were used to study the structure and optical properties of the material. The XRD results indicated that the TiO2:N layer was identified only as an anatase phase.
