Abstract:
Platinum surfaces are known to be among the most active ones for the oxidn. of carbon monoxide, whereas gold surfaces are completely inert for this reaction. The question remains: Do small clusters of these two metals maintain these distinct differences. To answer this question, we have employed temp.-programmed reaction (TPR) and Fourier transform IR (FTIR) spectroscopy to investigate the reactivity of small platinum and gold clusters consisting of up to 20 atoms. These clusters are generated i...     »
