A Comparative Study of Solvothermal and Sol-Gel-Derived Nanocrystalline Alumina Catalysts for Ethanol Dehydration

Table 1

Physical properties of alumina catalysts prepared by different methods.

Catalyst	Surface area (m^2/g)	Pore volume (cm^3/g)	Pore diameter (nm)	Crystallite size (nm)
Al-SV	215	0.770	9.33	3.78
Al-SG	152	0.221	3.46	4.78
Al-com	137	0.212	3.88	5.62

Crystallite size of alumina: determined by XRD results using Scherrer equation.
