| Summary: | This study introduces a novel type of electrocatalysts, where Pt and Ir nanoparticles were incorporated onto exfoliated acetylene black (FAB) substrate. These electrocatalysts were engineered to exhibit dual activity, simultaneously facilitating both oxygen reduction reaction and oxygen evolution reaction. The successful creation of these dual-function electrocatalysts, namely FAB180-Pt/Ir and FAB60-Pt/Ir, was confirmed through characterization techniques including transmission electron microscopy (TEM), x-ray photoelectron spectroscopy (XPS), energy-dispersive x-ray spectroscopy (EDS), and high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM). Ultimately, this bimetallic Pt-Ir catalyst, supported on exfoliated acetylene black (FAB), hold potential for application in Li-air batteries.
