Abstract
A nanocomposite comprising MgAl2O4 includes 1 weight percent (wt. %) to 10 wt. % nickel oxide and 1 wt. % to 10 wt. % cobalt oxide. The nickel oxide and the cobalt oxide are doped in the MgAl2O4. The nanocomposite is in the form of particles with an average particle size ranging from 1 nanometer (nm) to 8 nm and a surface area of 100 square meters per gram (m2/g) to 150 m2/g.
