MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202611050581 A) filed by Dr. B R Ambedkar National Institute Of Technology, Jalandhar, Punjab, on April 21, for 'method for photocatalytic degradation of chlorpyrifos in water using a sunlight-responsive nanocomposite.'
Inventor(s) include Dr Uma Shanker; and Rishabh.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a method (100) for photocatalytic degradation of chlorpyrifos in water using a sunlight-responsive nanocomposite, comprising steps of: preparing nitrogen-doped carbon quantum dots from biomass-derived kinnow (Citrus reticulata) peel powder by mixing the peel powder with an aqueous urea solution and subjecting the mixture to microwave irradiation to obtain nitrogen-doped carbon quantum dots, at step (102); synthesizing zinc hexacyanoferrate by reacting an aqueous solution of zinc nitrate with an aqueous solution of potassium ferrocyanide in presence of green tea extract and adjusting pH to alkaline conditions, at step (104); incorporating the nitrogen-doped carbon quantum dots into the zinc hexacyanoferrate matrix through in situ growth during formation of the zinc hexacyanoferrate framework to produce an N-CQDs@ZnHC nanocomposite, at step (106); contacting chlorpyrifos-contaminated water with the nanocomposite, at step (108); and exposing the mixture to natural sunlight to generate reactive oxygen species that degrade chlorpyrifos, at step (110)."
