Carbon aerogels were synthesized by a sol–gel process by polycondensation of phloroglucinol, resorcinol and formaldehyde, using sodium hydroxide, calcium hydroxide and sodium carbonate as the basic catalyst, respectively. The structure of carbon aerogels with different catalysts was characterized by scanning electron microscope, transmission electron microscopy and X-ray diffraction. The specific surface area, pore size distribution and pore volume were measured by surface area analyzer. The conductivity was measured by four-probe conductivity meter. The results show that the carbon aerogel in the presence of sodium carbonate has uniform network structure, specific surface area 623.34 m 2  g −1 , and the resistivity 0.173 Ω mm at pH 3.10.
