摘要：

As previously described in greater detail, diverse transition metal cluster cations are produced in an external source by sputtering with 20 keV Xenon ions and transferred to the ICR cell of a home-built Fourier transform mass spectrometer. There, they are thermalized by collisions with Neon atoms and stored for up to tens of seconds. They undergo a variety of reactions in the presence of ethene, benzene or ammonia, displaying different size-specific effects. Depending upon the metal and the actual cluster size, mere physical adsorption or dehydrogenation is prevailing.
