Abstract

The invention discloses a synthetic method of pore size-adjustable nanometer mesoporous CuAl2O4 spinel. The synthetic method is characterized by comprising the following steps of: reacting for 24 hours at the constant temperature of 80 DEG C by using Cu(NO3)2.3H2O and Al(NO3)3.9H2O as raw materials, using n-butylamine and dodecanol as co-template, and using water and alcohol as solvent; washing the product by water and alcohol, centrifugally separating and drying the washed product to obtain a copper-aluminum hydroxide coprecipitation precursor; roasting the precursor for 2 hours in a muffle furnace of 800 DEG C to obtain mesoporous CuAl2O4 spinel. The synthetic method of pore size-adjustable nanometer mesoporous CuAl2O4 spinel disclosed by the invention is reasonable in design, simple in process, smaller in product particle dimension, large in specific surface area, concentrated in pore size distribution and adjustable within a range of 5nm-17nm.
