MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611004274 A) filed by Malaviya National Institute Of Technology, Jaipur, Rajasthan, on Jan. 16, for 'nano-granular znco2o4 microplate decorated pt/c electrocatalyst for methanol electrooxidation.'
Inventor(s) include Dr. Sumanta Kumar Meher; Neeraj Lamba; and Gaurav Meena.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a method for preparing a nano-granular ZnCo2O4 microplate decorated with Pt/C as an electrocatalyst for methanol electrooxidation. The invention discloses a one-step hydrothermal process for synthesizing hierarchical ZnCo2O4 microplates composed of interconnected nanogranules with intra-plate porosity, followed by coupling with Pt/C through a reflux-assisted reduction method to form a uniform Pt/ZnCo2O4/C nanocomposite. The resulting material exhibits high phase purity, homogeneous Pt nanoparticle dispersion, and enhanced electrochemically active surface area. The electrocatalyst demonstrates five-fold higher mass activity, lower Tafel slope, reduced charge-transfer resistance, and superior CO-tolerance compared to conventional Pt/C. The composite retains structural integrity and catalytic stability even after extended electrochemical cycling, confirming its long-term durability. The invention provides a scalable, cost-effective method for developing high-performance Pt/ZnCo2O4/C catalysts applicable to direct methanol fuel cells and other low-temperature electrochemical energy conversion devices."
