| Abstract: | A new method for measuring hydrogen chemisorption on polymer‐stabilized metal colloids, in conjunction with variable coverage infrared spectroscopy of adsorbed CO, is applied to analyse the surface of Pt/polyvinylpyrrolidone colloids. The results correlate well with the measured activity of Pt/PVP as a hydrogenation catalyst. |
