Abstract

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 (R_ct) 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.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
