MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541116616 A) filed by Dr. Someshwar Pola; and Dr. G. Vijaya Lakshmi, Hyderabad, Telangana, on Nov. 25, 2025, for 'visible light-driven waste water treatment using smfeo3 and lafeo3perovskites: synthesis, characterization and photocatalytic degradation studies.'
Inventor(s) include Dr. K. Rammohan; Dr. Someshwar Pola; and Dr. G. Vijaya Lakshmi.
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 synthesis of perovskite LaFeCh (LFO) and SmFeCh (SFO) has progressed notably due to their potential in ecological decontamination through the photodegradation of Congo Red into environmentally benign byproducts. These perovskite crystalline materials were produced using the sol-gel method and extensively characterized using various techniques, including powder XRD, FESEM, EDS, UV-Vis-DRS, EIS, XPS, HRTEM, and VSM. The results confirmed the successful synthesis of LFO and SFO perovskites with an orthorhombic structure, crystallizing in the orthorhombic Ptutta space group. The La3+ ions are coordinated with eight O2" atoms in an eightcoordinate geometry. Both perovskites exhibited significant catalytic degradation of Congo Red over extended time intervals, leading to greater mineralization into products like CO2 and H2O. The photocatalytic activity of Congo Red is enhanced due to its reduced band gap energy and the efficient generation of OH* radicals, as shown by scavenger studies.
