▎ 摘　　要

NOVELTY - Preparing supported iridium group cluster catalyst, comprises (a) soaking the carrier in the iridium precursor solution; and (b) taking out the carrier, and heat-treating the carrier to obtain a catalyst of supported iridium group clusters. USE - The supported iridium group cluster catalyst is useful in the field of energy storage, and electrocatalytic oxygen evolution (claimed). ADVANTAGE - The method has simple process and easy operation, can prepare multiple high activity load type iridium-based cluster catalyst, and the obtained catalyst has low cost, high activity and high stability of electro-catalytic performance, and has obvious advantages in the energy storage field. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for supported iridium group cluster catalyst.
