A novel FeAlO3/g-CN (FAO/g-CN) material as an electrocatalyst with promising potential for OER

Energy is a primary requirement of the modern age, and water-splitting is recognized as a green energy source. Developing efficient, high-performance, and cost-effective electrocatalysts has become a significant pursuit in improving water-splitting productivity. In this context, a hydrothermally synthesized, advantageous, environmentally friendly and economically efficient FeAlO3/g-CN (FAO/g-CN) hybrid material enhances water oxidation. Multiple analytical methods examine the components' morphological, textural, structural, and compositional characteristics, highlighting the need for efficient and cost-effective solutions. The electrochemical characteristics of the FeAlO3/g-CN composite have been evaluated in a 1 M potassium hydroxide (KOH), revealing an extraordinarily lower overpotential (212 mV) at an optimal current density (j) of 10 mA/cm2. A minimum charge transfer resistance (Rct) of 0.04 Ω and notable longevity (50 h) indicates the synthesized material's outstanding prospects for oxygen evolution reaction (OER). Subsequent analysis has exposed a notably low Tafel value (32 mV/dec), signifying that FeAlO3/g-CN nanocomposite has enhanced electrocatalytic effectiveness and rapid reaction kinetics. The nanocomposite demonstrates significant applications for water electrolysis and other electrochemical activities, thereby underlining its potential impact on renewable energy.
