  • Electrocatalysts for oxygen evolution reaction and method of fabrication thereof
    Patent number: 12546019
    Abstract: The present disclosure relates to V and F-codoped cobalt hydroxide nanowires electrocatalysts V—Co(OH)2 comprises vanadium (V) at less stable 4+ oxidation state and fluoride (F) ions codoped directly on carbon cloth electrode. The V—Co(OH)2 produces excellent oxygen evolution reaction (OER) activity in alkaline conditions. The present disclosure also relates to a method of fabrication of the V and F-codoped cobalt hydroxide nanowires electrocatalysts V—Co(OH)2 comprising vanadium (V) at less stable 4+ oxidation state and fluoride (F) ions codoped directly on carbon cloth electrode by hydrothermal reaction.
    Type: Grant
    Filed: November 23, 2022
    Date of Patent: February 10, 2026
    Assignees: King Khalid University, RCAMS, SASTRA Deemed University
    Inventors: Abdullah G. Al-Sehemi, Pandi Muthukumar, Periyappan Nantheeswaran, Mariappan Mariappan, Savarimuthu Philip Anthony, Mehboobali Pannipara
