| Abstract: | In this paper, we have reported the synthesis of highly-ordered mesoporous material with domestic AucP as templating agent. The product has a BET surface area of 534.8m2·g-1, pore size of 4.6nm and pore volume of 0.68cm3·g-1. The synthesis cost of FDU-7 is much lower than that of SBA-15 (just 25% of SBA-15), which will be much helpful to the industrialization of such mesoporous materials. |
