The research community is actively exploring ways to create cost-efficient and high-performing electrocatalysts for the oxygen evolution reaction. In this investigation, an innovative technique was employed produce heteroatom-doped carbon containing NiCo oxides, i.e., HC/NiCo oxide@800, in form of a three-dimensional hierarchical flower. This method involved reduction bimetallic (Ni, Co) metal–organic framework, followed by carefully controlled oxidative calcination. resulting porous flower-like structure possess numerous advantages, such as expansive specific surface areas, excellent conductivity, multiple electrocatalytic active sites both hydrogen reactions. Moreover, presence vacancies within oxide@800 significantly enhances conductivity substance, thus expediting kinetics processes. These benefits work together synergistically enhance performance oxide@800. Empirical findings reveal that demonstrate exceptional catalytic activity, minimal overpotential, remarkable stability when deployed reactions alkaline environments. investigation introduces fresh avenue creating composite transforming frameworks with controllable structures. approach holds promise advancing electrochemical energy conversion devices facilitating development efficient customizable materials.
