INNOVATIVE HYBRID ANODIC ELECTRODE FOR WATER ELECTROLYSIS: SYNERGISTIC COMBINATION OF MAGNESIUM FERRITE, HARD CARBON, AND RUTHENIUM OXIDE FOR ENHANCED ELECTROCHEMICAL EFFICIENCY

Water electrolysis represents a promising technology for green hydrogen production, necessitating the development of efficient and stable electrodes. In this study, we present the design and characterization of an innovative hybrid anodic electrode that incorporates a synergistic combination of magnesium ferrite (MF), hard carbon (HC), and ruthenium oxide (RuO2). Commercial electrodes typically consist of single materials with limited catalytic activity and durability. In contrast, the hybrid anodic electrode demonstrates significant improvements in electrochemical efficiency. The MF component serves as a robust supporting structure, providing thermal stability and corrosion resistance, ensuring prolonged electrode lifespan during the electrolysis process. The inclusion of HC, derived from lignin pyrolysis, offers conductivity and a porous surface that facilitates ion diffusion. The addition of RuO2 as a catalyst for the Oxygen Evolution Reaction (OER) enhances overall electrochemical efficiency, promoting oxygen generation at the anode during water electrolysis. Comprehensive analyses were conducted using electrochemical, structural, and morphological characterization techniques such as X-ray diffraction (XRD), thermogravimetric analysis (TGA), specific surface area determination using the BET analysis, and scanning electron microscopy (SEM). These analyses provide detailed insights into the structure, chemical composition, and surface properties of the hybrid anodic electrode.
