• Pt single crystal
• Thin metal films
• Cyclic voltammetry
• Pt(111)

A simple and quick method for forming Pt(111)-like thin films on Sun substrates for electrochemical and/or electrocatalytic experiments is reported. This method involves physical vapour deposition followed by flame annealing, electrochemical cleaning and a short heat treatment under a controlled atmosphere. Careful selection of the substrate, surface preparation and cooling atmosphere allows production of Pt thin films which show voltammetry features typical of large Pt(111) single crystal electrodes in 0.1 M HClO4. This technique promises a method for the production of Pt(111) type surfaces on a larger scale.
