I want to make Al2O3 nano particles by sol-gel method. Would you please give me the details about the same?
Journal of Sol-Gel Science and Technology June 2004, Volume 30, Issue 3, pp 135-140
Sol-Gel Synthesis of Transparent Alumina Gel and Pure Gamma Alumina by Urea Hydrolysis of Aluminum Nitrate.
You can find the details about a synthesis method for Al2O3 nano particles by sol-gel method.

Please follow this link, its a best paper for synthesis of alumina nanoparticles
Hi..Janki, there are a lot of articles concerning on Alumina preparation (from old to the newest one in this internet, you have to specify which alumina do you mean). For examples : http://www.mdpi.com/1996-1944/5/2/336/pdf ; http://wjoe.hebeu.edu.cn/ICCE-proceedings%20Hawaii% 20USA/Seetala, %20N.V. %20 (Grambling%20St.U.,%20LA)%20%20903.pdf ; http://www.ceramics-silikaty.cz/2011/pdf/2011_04_378.pdf , and http://www.ijcea.org/papers/172-A663.pdf
Hope this will be useful.
the sol-gel synthesis consisted
in the preparation of a 0.1 M AlCl3 ethanolic solution.
By adding a 28% NH3 solution (p.a. Fluka) a gel was formed. The gel was let to
maturate for 30 hours at room temperature and then dried at 100o
C for 24 hours.

Mild shaking at 90o
C for10 hours was utilised. The gel was let to maturate at
room temperature for 24 hours, and then dried at 100o
C for 24 hours.
The resulting gels were calcined in a furnace for 2 hours (heating rate
20o
C/min.), at temperature values of 1000o
C and 1200o

what is the main difference between alpha Al2O3 and gamma Al2O3 nanoparticles?
