Synthesis of Pt75Sn25/SnO2/CNT nanoscaled electrode: Low onset potential of ethanol electrooxidation

► A pulsed laser synthesis is used for the deposition of Pt, SnO2 and PtSn alloy thin films onto carbon nanotubes. ► These nanoscaled materials were characterized by FESEM, TEM, XRD and XPS. ► Enhanced electrocatalytic properties toward ethanol oxidation.
