20. A method of manufacturing a nanocomposite, the method comprising:
combining a magnesium salt, aluminum salt, and a ferric salt in an aqueous solvent comprising menthol or dextrose, to obtain a first mixture;
heating the first mixture to remove at least 99.5 wt. % of the aqueous solvent to obtain a first solid;
grinding the first solid into a first powder;
calcining the first powder at a temperature in a range of from 600 to 800° C. for a time in a range of from 2 to 4 hours to obtain a second solid;
grinding the second solid and urea, in a ratio of 2 to 100 parts by weight of the urea to 1 part by weight of the second solid, to form the nanocomposite, into a second powder;
heating the second powder at a temperature in a range of from 550 to 650° C. for a time in a range of from 15 minutes to 1.5 hours to obtain the nanocomposite, comprising graphitic C3N4, Fe2O3, and MgAl2O4 in a mass relationship to each other in a range of from 5 to 15:2 to 7:75 to 95.
