A metal-containing surfactant [Co(HED3A)]-N+ formed by trisodium N-hexadecyl ethylenediamine triacetate (3NaHED3A) and CoCl2 was first used as template for synthesizing Co3O4/SiO2 mesoporous composite. TG showed that the proper temperature for removal of template is 600??C. Nitrogen adsorption-desorption isotherms data confirmed that the composite has a high specific surface area and uniform pore...
