Abstract
Cobalt-based structured electrocatalysts have emerged as a promising solution for water splitting, offering advantages such as high surface area, abundant active sites, and tunable chemical compositions. These studies explore different cobalt-based electrocatalysts, including both Co3O4 and CoP or CoS2 in composite structures with highly conductive carbon. Presented here is the influence of carbon addition on the physicochemical and electrochemical properties of composites in both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Importantly, the impact of carbon incorporation is material-dependent, enhancing performance in some cobalt-based systems while slightly reducing it in others due to interfacial compatibility and electronic interaction. Analyzing the Tafel slope for the oxygen evolution reaction, the materials CoP (60 mV dec−1), Co3O4 (54 mV dec−1), and Co3O4/C (64 mV dec−1) exhibited lower values compared to the commercial IrO2/RuO2 catalyst, which had a Tafel slope of 71 mV dec−1. Co3O4 showed the best performance, with efficient electron transfer properties and favorable reaction kinetics, making it particularly effective during the OER process. The catalysts demonstrated stable performance under continuous current for over 70 h. The efficiency is attributed to optimized electronic properties and active sites, supporting fast hydrogen production with minimal energy expenditure.
