1. A method for hydrogen generation, comprising:

contacting a graphite-phase carbon nitride cobalt oxide and magnesium aluminum oxide (g-C₃N₄@CoO/MgAl₂O₄) nanocomposite with sodium borohydride in water; and

hydrolyzing the sodium borohydride to generate hydrogen,

wherein the g-C₃N₄@CoO/MgAl₂O₄nanocomposite comprises a graphite-phase carbon nitride (g-C₃N₄) in an amount of 5 to 15 percent by weight (wt. %), cobalt oxide in an amount of 1 to 10 wt. %, and magnesium aluminum oxide (MgAl₂O₄) in an amount of 75 to 95 wt. % based on a total weight of the g-C₃N₄@CoO/MgAl₂O₄nanocomposite.
