Cover Story: This study addresses climate change challenges and rising CO2 emissions, exploring hydrogen technology as a sustainable solution. Nickel phosphide-based electrocatalysts, known for efficient oxygen evolution reactions, are emphasized. A simple method is devised to produce porous carbon flakes from cellulose, yielding a highly porous structure after carbonization. This carbon serves as a support for Ni12P5, showing optimal performance in a 100:1 mass ratio for the composite. Electrochemical tests reveal superior kinetics for OER, with the composite demonstrating the most stable behavior under high current density. Durability tests confirm its promise for practical applications, and post-OER analysis indicates no undesired reactions or product release, ensuring stable behavior. This provides a direct method for creating a cellulose-derived composite with enhanced electrochemical activity. View this paper
