However, the efficiency of hydrogen evolution (HER) during this electrocatalysis is usually regulated by the proficiency of the catalyst in generating a facile oxygen evolution reaction (OER). In this work, the robust bifunctionality of Ni-doped VO2(B) as an electrocatalyst for hydrogen and oxygen evolution reactions is investigated. The optical characterization uncovered the semiconducting nature of nanoflake-like VO2(B) nanostructures. Furthermore, optimizing Ni concentration resulted in significant reduction of overpotentials from 518 mV to 289 mV for HER and from 435 mV to 404 mV for OER under a current density of 10 mA/cm2. This excellent electrochemical efficiency of the Ni-doped VO2(B) nanostructures is further showcased by the low Tafel slope values of 129 mV/dec and 99 mV/dec for HER and OER, respectively. Consistent with these findings, the materials exhibited minimal charge transfer resistance of 57.1 ?, reinforcing the superior electrocatalytic activity. Additionally, the chronopotentiometric studies confirmed the long-term stability of the nanostructures. Altogether, Ni-doped VO2(B) nanostructures can be considered as a potential electrocatalyst for overall water electrolysis, laying the foundation for a sustainable energy future. 2025 Elsevier B.V.
