Abstract

In the current paper, the mixed SiO2/Al2O3 aerogel was synthesized by sol-gel method with subcritical drying and characterized. Tetraethoxysilane was used as a precursor of silicon sol. The flower-shaped alumina suspension was peptized to produce alumina sol. The aerogel texture, morphology, and structure were determined using scanning electron microscopy, X-ray diffraction, low-temperature nitrogen adsorption, and high-resolution spectroscopy. A special attention was paid to the pore structure of aerogel, and aerogel framework was formed by the spherical agglomerates containing spherical particles of silicon oxide and alumina nanopetals. The pore size distribution was bimodal with peaks of 5.5?nm and 77?nm.
