A facile and novel route for dual-template method synthesis of mesoporous silica material Al-Ce-SBA-15

Abstract A kind of ordered mesoporous material Al-Ce-SBA-15 was successfully prepared by the method of dual-templates CTAB and P123 with adding appropriate amount of Al through a one-step hydrothermal synthesis. The prepared Al-Ce-SBA-15 material was characterized by XRD, EDX, HRTEM, SEM, FT-IR and N 2 adsorption-desorption isotherm technique. The results showed that the heteroatoms Al and Ce highly dispersed on the surface of SBA-15 and the prepared Al-Ce-SBA-15 material still retained a desirable ordered mesoporous structure, high specific surface area, large pore volume and narrow pore size distribution. Especially, a uniform coating layer was formed on SBA-15, and the aggregation of metal Ce was avoided by adding appropriate amounts of Al.
