Doped graphitic carbon nitrides, methods of making and uses of the same

Carbon-doped graphitic carbon nitride (g-C.sub.3N.sub.4) compositions are synthesized from the chemical precursors melamine, cyanuric acid and barbituric acid. Phosphorus-doped g-C.sub.3N.sub.4 compositions are synthesized from the chemical precursors melamine, cyanuric acid and etidronic acid. Carbon- and phosphorus-doped g-C.sub.3N.sub.4 compositions, when in the presence of UV or visible light, can be used in water treatment systems to photocatalytically degrade persistent organic micropollutants such as pharmaceuticals and personal care products (PPCPs), endocrine disrupting compounds (EDCs), pesticides, and herbicides. Carbon- and phosphorus-doped g-C.sub.3N.sub.4 compositions can also be applied to surfaces of household and public items to kill protozoa, eukaryotic parasites, algal pathogens, bacteria, fungi, prions, viruses, or other microorganisms, preventing the transfer thereof between users.
