MoS2 has emerged as a highly promising catalyst for the hydrogen evolution reaction (HER) owing to its exceptional catalytic properties. However, there is pressing need further enhance reactivity and integrate oxygen (OER) capabilities facilitate industrial implementation. In this context, dual-metal doping approach presents straightforward effective strategy achieve superior performance. Systematic characterization electrochemical evaluations reveal that synergistic effects of Co Fe significantly both HER OER activities, demonstrating remarkable potential practical applications in energy conversion storage systems. The unique flower-like architecture material endows it with substantially enlarged surface area, which increases exposure active sites facilitates enhanced activity. Specifically, achieves low overpotentials −127 292 mV at 10 mA cm−2 alkaline media, respectively, demonstrates excellent stability over h test. This research provides valuable insights into development advanced materials capable efficiently performing processes, paving way sustainable technologies.
