Chemical reaction of platinum cluster ion with methanol and ethylene was investigated by using the FT-ICR (Fourier Transform Ion Cyclotron Resonance) mass spectrometer. Metal clusters with 3-7 were generated by a pulsed vapor laser-vaporization supersonic-expansion cluster beam source directly connected to FT-ICR mass spectrometer. Observed reactions are mainly chemisorptions of methanol and ethylene with dehydrogenation. It also shows that the number of CO molecules which can stably attach to the platinum surface depends on cluster size.
