MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202541117207 A) filed by The Principal, Mepco Schlenk Engineering College, Sivakasi, Tamil Nadu, on Nov. 26, 2025, for 'green combustion method for synthesizing zinc mixed cerium vanadate nanoparticles using tulsi extrac.'
Inventor(s) include Dr. P. Raji; and R. Gowsalya.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "Zn-doped cerium vanadate (ZnxCei-xVO4) nanoparticles were prepared via a sol-gel autocombustion method, providing a simple, economical, and eco-friendly approach. XRD confirmed the formation of a tetragonal zircon-type crystal structure with high phase purity, while FTIR revealed characteristic metal-oxygen bonding vibrations, validating the successful formation of the vanadate framework. FESEM coupled with EDX displayed homogeneous elemental distribution and uniform nanoparticle morphology, further supported by TEM and SAED, which confirmed nanoscale dimensions and polycrystalline nature. The CV profiles exhibited distinct redox peaks, confirming pseudocapacitive behaviour originating from reversible faradaic reactions. The tetragonal zircon-type crystal structure of ZnxCei. X VO4 nanoparticles facilitates fast ion transport and reversible redox processes, enabling a high specific capacitance of 338 F g"1 at 1 A g' 1, along with an energy density of 67.57 Wh kg' 1 at a power density of 454.67 W kg-1. The electrode exhibited remarkable cycling stability, ^maintaining 87.01% of its original capacitance after 3000 successive chargedischarge cycles, highlighting its strong durability and suitability for high-performance supercapacitor applications."
