Electrocatalytic properties of electrochemically deposited Pt ultra-thin films on Au single crystal electrode surfaces for oxygen reduction reaction (ORR) were investigated. Although it was reported that the order of activity of low index faces of the Pt single crystal electrodes increased in the sequence Pt(100) < Pt(111) < Pt(110), the order of activity of Pt ultra-thin films electrodeposited on the low index faces of the Au single crystal electrodes increased in the sequence Pt/Au(111) < Pt/Au(110) < Pt/Au(100), which was same trend of the Au single crystal substrates.
