MUMBAI, India, Nov. 21 -- Intellectual Property India has published a patent application (202521103581 A) filed by Dr. Sapna Bakul Jadhav, Palghar, Maharashtra, on Oct. 28, for 'synthesizing heteroatom-doped porous carbon materials using cow urine.'
Inventor(s) include Dr. Sapna Bakul Jadhav; and Dr. Pradip B. Sarawade.
The application for the patent was published on Nov. 21, under issue no. 47/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to A process for synthesis of heteroatom-doped porous carbon material from cow urine. Cow urine is an abundant yet underutilized organic waste product with potential applications in material science. This work presents developing highly porous carbon materials doped with heteroatoms such as sulfur (S), nitrogen (N), and phosphorus (P) using cow urine as the primary precursor. The process involves spray drying, which facilitates the integration of heteroatoms into the carbon structure without requiring expensive templates or heteroatom-rich precursors. The resulting "Urine Doped Porous Carbon" (UPC) exhibits significant porosity due to the natural organic matter and salt particles present in urine. This novel material demonstrates excellent electrocatalytic activity for applications such as the oxygen reduction reaction (ORR), hydrogen evolution reaction (HER), dye degradation, and energy storage devices, including supercapacitors and batteries. UPC rivals state-of-the-art platinum-carbon (Pt/C) catalysts in performance while offering superior stability due to its heteroatom doping and enhanced textural properties. This approach not only provides a cost-effective alternative to expensive electrocatalysts but also transforms waste into a valuable nanomaterial, contributing to both sustainability and energy research."
