The zinc-based composite aerogel was prepared by the sol-gel method using ZnCl2 as precursor, polyacrylic acid (800, 1800, 5000) as template, and propylene oxide as initiator. The characterization of aerogels was carried out by field-emission scanning electron microscope (FESEM), high-resolution transmission electron microscopy (HRTEM), and N2 adsorption/desorption. The results suggested that the zinc-based composite aerogel made by polyacrylic acid (1800) had perfectly three-dimensional networks and the skeletal was composed of particles in nanometer and had a high surface area about 236 m2/g. The N2 adsorption/desorption showed the aerogel had an average pore-diameter of 11 nm and a total pore volume of 0.179 cm3/g.
