MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641018072 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Feb. 18, for 'biocompatible zinc oxide-graphene oxide nanocomposite photocatalyst for organic pollutant degradation.'
Inventor(s) include Gunapriya K; Poomani A F; Annapoorni K N; and Krishna Chandar N.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a zinc oxide-graphene oxide nanocomposite photocatalyst that includes graphene oxide sheets (GO) and zinc oxide nanoparticles (ZnO) distributed on surfaces of the graphene oxide sheets, wherein the zinc oxide nanoparticles are anchored to the graphene oxide sheets through interfacial bonding. The graphene oxide sheets exhibit a wrinkled sheet-like morphology with oxygen-containing functional groups. The zinc oxide nanoparticles have a hexagonal wurtzite crystal structure. The nanocomposite photocatalyst is synthesized by dispersing graphene oxide in an aqueous medium via ultrasonication, adding zinc oxide nanoparticles to the graphene oxide dispersion, stirring the mixture at elevated temperature, collecting the precipitate by centrifugation, and drying to obtain the nanocomposite. The nanocomposite photocatalyst degrades organic pollutants in wastewater through photogenerated electron transfer from zinc oxide nanoparticles to graphene oxide sheets, which suppresses electron-hole recombination and generates reactive oxygen species including superoxide radicals and hydroxyl radicals."
