Abstract
A nanocomposite material including iron sulfide (FeS2) nanoparticles, iron oxide (α-Fe2O3) nanoparticles, titanium dioxide (TiO2) nanoparticles, and graphitic carbon nitride (C3N4) nanosheets and a method of its preparation. The nanocomposite is used in a method of forming oxygen gas from water using an applied voltage and photoirradiation, a method of forming hydrogen gas from water using an applied voltage and photoirradiation, and a method of photodegrading organic pollutants using visible light photoirradiation.
