Abstract |
Noble metal-based multi-metallic composite nanocatalyst received a tremendous attention for electrocatalytic oxygen evolution reaction (OER). Over the decades, a major attention has been paid to the strategy of alloying with transition metals for increasing the catalytic activity with the effect of surface energy control. However, the issues of durability are still an ongoing challenge for the next generation of nanocatalyst. Recently, we found the facile route to the introduction of phosphorous into the alloyed nanocrystals that changes the surface anionic environment, which is directly related to the enhancement of OER activity and durability. Through further treatments for the sufficient exposure of active sites, we have successfully synthesized dendrite structured iridium-based phosphide nanoparticles and these exhibit great electrocatalytic performance toward OER. |
