MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511113800 A) filed by Chandigarh University, Mohali, Punjab, on Nov. 19, 2025, for 'hybrid organic-inorganic nanobiochar for water remediation.'
Inventor(s) include Harvinder Singh Sohal; Sanyojak Kanwal; Navneet Kaur; and Manvinder Kaur.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The present invention introduces a trimetallic magnetic Fe2O3@NBC/BaMoO4 catalyst synthesized using nanobiochar derived from biowaste peanut shells, designed for efficient photocatalytic degradation of numerous dyes under UV light. The structural and optical characterizations confirmed successful integration with UV-Vis, revealing a 4.56 eV band gap, and FTIR, XRD, SEM, and DLS analyses indicating well-dispersed nanoparticles with good colloidal stability. The VSM analysis showed a reduced magnetization, while electrochemical studies demonstrated strong redox activity and an electroactive surface area of 0.0007 cm2. The catalyst achieved 97.4% dye degradation within 120 minutes (rate constant 0.2871 min-1) at pH 5 and retained 90.2% efficiency after five cycles with minimal structural changes. The reactive oxygen species studies identified superoxide and hydroxyl radicals as primary active species, and GC-MS confirmed complete dye mineralization. These findings establish the catalyst as a stable, UV-responsive, and sustainable solution for wastewater treatment."
