Abstract: A composite is synthesized by pyrolysis of a mixture of tannin and melamine. The synthesis process comprises dissolving the tannin and the melamine in water to form a homogeneous solution; evaporating the solution to yield a dry solid; and subjecting powders of the dry solid to a heat treatment at a temperature for a duration of time effective to produce the composite.

Abstract: Carbon-doped graphitic carbon nitride (g-C3N4) compositions are synthesized from the chemical precursors melamine, cyanuric acid and barbituric acid. Phosphorus-doped g-C3N4 compositions are synthesized from the chemical precursors melamine, cyanuric acid and etidronic acid. Carbon- and phosphorus-doped g-C3N4 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-C3N4 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.
