The microstructure of the resultant core-shell ZrO2/SiO2 aerogel was characterized by scanning electron microscopy, X-ray photoelectron spectroscopy and transmission electron microscopy. Appropriate choice of formamide and tetraethoxysilane solution allowed the formation of the core-shell ZrO2/SiO2 aerogel with a BET surface area of 619m2/g, a pore size of 8.2nm and a bulk density of 0.202g/cm3.
