This study outlines the methodology to electrodeposit well-defined iridium nanospheres onto glassy carbon electrodes, using a square wave potential technique. Such work has been before on other noble metals, but for the first time, such deposits can be obtained for iridium. Other studies were only able to deposit aggregates of iridium, or nanoporous particles with a few nanometers in size. In addition, particle size and iridium loading can be connolled by altering certain parameters in the electrodepesition process. Deposits were characterized using cyclic voltammetry and scanning electron microscopy
