摘要：

Ordered mesoporous alumina with a large surface area was successfully synthesized in this work. Employing P123 as a structure-directing agent, the ordered mesostructure was fabricated only when the molar ratio of salicylic acid to citric acid was 2, and the large surface area was attributed to the addition of salicylic acid. The resulting alumina possesses a surface area of 520.65 m(2) g(-1) and a pore volume of 0.82 cm(3) g(-1). The surface area is still 300.20 m(2) g(-1) even after being calcinated at 800 degrees C.
