Abstract

It has long been recognized in heterogeneous catalysis that the efficiency of a catalyst can be enhanced by supporting it on a solid having large surface area. This is particularly true in the case of metal catalysts. The formation of a highly dispersed metal catalyst on the surface of a carrier comprises thermal decomposition and reduction of metal compounds followed by crystallization and aggregation of the metal thus formed. It appeared that the dispersion, the adsorption properties as well the catalytic properties of the metal depended strongly on the operating condition followed in the preparation procedure. Several physical methods have been used to study the physical and chemical properties of supported metal catalysts. In this paper some aspect of the results obtained by electron spin resonance, ferromagnetic resonance and infrared spectroscopy will be reviewed.
