In situ STM observation with atomic resolution on platinum film electrodes formed by a sputtering method

The first high-quality in situ STM atomic images of sputtering-deposited platinum film electrodes potentiostated at 0.15 V (vs. RHE) in 0.1 M HClO4 are reported showing that potential-induced hydrogen adsorption effectively cleaned the Pt surfaces with predominantly (111)-oriented facets.
