A dry chemical method for dispersing Ir nanoparticles in the pores of activated carbon and their X-ray absorption spectroscopy analysis

Ir nanoparticles are finely dispersed over whole particles of activated carbon (AC) via the gas phase adsorption of an organoiridium complex in the AC and subsequent heat treatment. Structural analysis of the supported Ir is performed in combination with X-ray absorption spectroscopy. Ir nanoparticles are finely dispersed inside the pores of activated carbon (AC) via the gas phase adsorption of an organoiridium complex in the AC and subsequent heat treatment. X-ray absorption spectroscopy reveals the structure of the supported Ir.
