摘要:
A super-microporous zirconia-alumina (pore size in the range of 1-2 nm) with narrow pore size distribution has been synthesized successfully by using an inexpensive nonionic surfactant fatty alcohol polyoxyethylene ether (AEO-7) as the template in ethanol solvent. As the Zr/Al molar ratio is 0.1, the material has high surface area of 413 m(2)/g and a large pore volume of 0.17 cm(3)/g after calcination at 400 degrees C. Even after calcination at 900 degrees C, the microporous structure remained, exhibiting a significant thermal stability. (C) 2014 Elsevier B.V. All rights reserved.
