MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541123461 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 8, 2025, for 'a multilayer cylindrical electrochemical device with radial diffusion for catalytic and alkaline conversion of airborne pollutants.'
Inventor(s) include Dr. D. Revathi; M Guhan; G Mownika; and J A Aasinth.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The newly developed device provides a multilayer cylindrical electrochemical air-purification system for the removal of gaseous pollutants such as CO, CO~, SOz, NO., VOCs, 0,, NH,, and particulate matter by integrating catalytic, alkaline absorption, and electrochemical reaction mechanisms. The device is incorporated with an air-handling chamber fitted with an inlet fan, a coarse mesh barrier, and an outlet fan and also holds a cylindrical reactor at the centre. The incoming air flows into an axial pipe with multiple nozzles that evenly distribute the air radially outward across seven concentric functional layers. The functional layers with a pre-filter cloth, a MnOz-activated carbon catalyst layer, a nickel mesh collector, an alkaline KOH/NaOH-infused melamine sponge, a PV A-KOH gel layer, a nickel mesh cathode, and a zinc anode were concentrically arranged inside the cylindrical reactor. When air flows outward through each layer, contamiilants are removed layer by layer through filtration, catalytic oxidation, chemical absorption, and electrochemical transformation. This multilayer cylindrical electrochemical device with radial-diffusion for catalytic and alkaline conversion of airborne pollutants enables the removal of multiple pollutants simultaneously with high-efficiency and provides a patentably new approach to a compact air-cleaning system."
