Abstract
A method of water purification includes mixing contaminated water with a cobalt oxide/calcium silicate @graphitic carbon nitride (CoO/CaSiO@g-CN) nanocomposite material to form a reaction mixture, exposing the reaction mixture to light, and removing the nanocomposite material using filtration to form purified water. The nanocomposite material includes hexagonal metal oxide nanoparticles including a CoO phase and a CaSiOphase dispersed on a matrix of g-CNnanosheets, where the hexagonal metal oxide nanoparticles have an average particle diameter in a range from 340 to 440 nanometer (nm). The nanocomposite material has a band gap energy in a range from 1.5 to 3.75 electron volt (eV).
