Abstract
Electrochemical water splitting is critical to produce green hydrogen without greenhouse gas emissions. Iridium-based catalysts are important for increasing the oxygen evolution reaction (OER) efficiency of water splitting, but their high cost and scarcity require the development of new electrodematerial structure. Alloyed nanoparticles have modified electrochemical structure for improved OER activity andstable support such as perovskite oxide can be applied due to its high oxygen transfer rate. This research focuses on developing iridium-transition metal alloy nanoparticles on a stable perovskite support to improve OER performance and durability. The changes in particle size, composition, and temperature-controlled structure are the main research topics, highlighting balancing activity and economics to produce hydrogen in an environmentally friendly way.
