Abstract
The present work investigates electrochemical oxidation of chlorine using cobalt oxide (Co3O4) nanoparticles synthesized through a co-precipitation method, resulting in a cubic lattice structure with space group Fd-3m (227). This study demonstrates that Co3O4 nanoparticles exhibit superior performance compared to noble electrocatalysts in chlorine evolution reactions (CERs). Key electrocatalytic parameters were optimized, with Co3O4 achieving an overpotential of 120 mV at a current density of 10 mA cm−2, a Tafel slope of 112 mV d−1 and a charge transfer resistance of 9.6 Ω. Additionally, wettability results revealed that cobalt oxide possesses minimal hydrophobicity, which helps in faster chlorine evolution process. We believe, this study provides valuable addition in understanding the designing of effective electrocatalysts for CER.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
