  • Ce and Zn-doped NiFe2O4 catalysts for urea fuel cells
    Patent number: 11827529
    Abstract: Ce and Zn doped NiFe2O4 materials synthesized via a sol-gel method used as a catalyst. The NiFe2O4 catalysts doped with Ce and Zn exhibit distinctive electrocatalytic activity towards urea oxidation. The Ce and Zn-doped NiFe2O4 catalysts can play a critical role as catalytic moderators, accelerating charge transfer in the anodic part of the urea fuel cell (UFC) and potentially improving the efficiency and cost of UFCs. These materials provide a promising approach for developing novel, non-precious electrodes for next-generation fuel technologies.
