MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641049730 A) filed by Btp Madhav; and Koneru Lakshmaiah Education Foundation, Vaddeswaram, Andhra Pradesh, on April 18, for 'synthesis of titanium dioxide-silicon dioxide (tio2-sio2) nanocomposite from earth-abundant natural rutile and quartz minerals.'
Inventor(s) include N. Ravivarman; S. Arunmetha; A. Pandian; and B T P Madhav.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The TiO2/SiO2 nanocomposite was synthesized from earth-abundant, naturally occurring rutile and quartz sand. Here, we opted for a simple, cost-effective, and low-equipment acid extraction and base hydrolysis method to address the limitation in scaling up nanomaterials. Materials characterization confirms the following claims. Although the X-ray diffraction pattern validates the formation of pure anatase TiO2, no evidence of SiO2 could be identified. The SEM micrograph clearly shows spherical morphology of a substance grown on the TiO2 surface, which could be a SiO2 nanoparticle. In addition, HR-TEM elemental mapping showed that Si was uniformly dispersed throughout the scanned area. The X-ray photoelectron survey of the synthesized sample indicated the successful formation of Si-O-Ti bonds, providing clear evidence of TiO2-SiO2 nanocomposite formation. Finally, the proposed method, which directly converts naturally occurring minerals into nanomaterials and nanocomposites, has an impact on industry, especially in semiconductor-related research, which has yet to be explored to any significant extent. Herein, we demonstrate an effective method for preparing TiO2/SiO2 nanocomposites via sulfate extraction and base hydrolysis, followed by washing and calcination. The prepared nanocomposites are in the nanometer range (~100nm), high-purity, and possess exceptional surface area."
