    NiFe co-doped TiO2 as a high-performance bifunctional photocatalyst for enhanced oxygen evolution and reduction reactions in efficient zinc-air battery systems by Md Iftekher Hossain, Foysal Kabir Tareq, Souman Rudra

    Published 2025-07-01
    “…This study underscores the significant influence of Ni and Fe transition metal doping, as well as NiFe co-doping, on enhancing the properties of TiO2 to address the critical challenges in developing high-performance photo-assisted Zn-air batteries, particularly the need for improved light absorption, charge carrier separation, and catalytic efficiency. The doping process notably enhances light absorption and charge carrier separation, while the reduction in TiO2 crystallite size increases the surface area and shortens charge carrier diffusion paths, thereby minimizing recombination rates and improving photocatalytic efficiency. …”
