Although a number of anodic materials have exhibited catalytic activity approaching that of iridium (or ruthenium) oxide catalysts for the electrochemical water splitting, research demand for new catalyst development is constantly required. The electrochemical water splitting has long been considered a promising approach to producing clean hydrogen fuel using renewable energy sources. The hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) are the major half reactions occurring in the cathode and the anode respectively in the electrochemical water splitting reaction. Herein, we develop a cost-effective and new corrosion method for transforming hollow cobalt mesospheres into highly active and stable catalysts for OER. The Co catalysts obtained by corrosion reaction were characterized by X-ray diffraction, transmission electron microscopy, and scanning electron microscopy. We also investigate the electrocatalytic activity of the Co catalysts for OER and compare them with commercial carbon-supported iridium. This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIT) (No. 2019R1F1A1049614
