Provisional Patent Application Filed

A growing number of persistent organic micro-pollutants such as pharmaceuticals and personal care products, pesticides, and herbicides are frequently observed in natural and treated water. Such contaminants are recalcitrant to conventional water and wastewater treatment and may pose risks to human and ecological systems even at very low concentrations. In addition, persistent pathogens, which maybe airborne or water-borne, can also cause the spread of infectious diseases. Thus, the effective control against such pathogens and micropollutants is important to protect the public health.

George Washington University researchers invented a carbon-doped graphitic nitride (g-C3N4) photo-catalyst composition that can, in the presence of UV or visible light, degrade persistent organic micro-pollutants.  In other words, this novel g-C3N4 composition can, under UV or regular light, effectively treat pharmaceuticals, pesticides, herbicides, and other organic pollutants in water or wastewater. Furthermore, the g-C3N4 composition can be coated to surfaces of household or public items where the coating can kill harmful viruses, bacteria, and other pathogens and thus improving human hygiene.

This novel carbon-doped graphitic nitride photo-catalyst maybe applied to a variety of household or industrial applications, including as a coating on food packages, plates, and kitchen counter-top. In presence of UV or visible light, the novel photo-catalyst can help degrading harmful organic pollutants and pathogens and thus improve health and hygiene. Similarly, the carbon-doped graphitic nitride photo-catalyst can be coated onto hand-gripping surfaces of furniture, doors, and other appliances to help degrade bacteria and virus and therefore slows the spread of diseases or allergy-causing substances.


  • Water Treatment
