Catalysis SSIMS

The usefulness of SSIMS in the field of catalysis-related surface science is already well known. SSIMS studies of CO adsorption on single-crystal surfaces of Cu, Ru. Ni, Pd and Pt have been summarized briefly [45). The ob.ser-vation that different CO adsorption structures (linearly bonded, bridged, triple bridged and mixed states) can be distinguished by the characteristic MeiCO+ (-V = 1, 2, 3) secondary cluster-ion yield fractions in the SSIMS spectra, i.e.. by fingerprinting, confirms that these rather delicate structures can be identified by the method.
