Supported copper particles are widely used in heterogeneous catalysis. Influence of supports of different nature on the Cu particles formation is studied by the methods of UV-Vis spectroscopy of diffuse reflectance, XRD and electron microscopy. Different states of supported copper have been identified by UV-Vis spectroscopy: absorption bands at 250 (Cu + ), 320-370 and 400-440 (charge transfer...
