Abstract 

The formation of copper phyllosilicate in Cu/SiO2 catalyst was intensively studied in this paper. Samples were taken during the catalyst preparation procedure and systematically characterized by N2-adsorption, FTIR, XRD, and TEM. The characterization showed that the ion-exchange between copper ammonia complex and Si—OH took place in the aging stage while copper phyllosilicate formed during the ammonia evaporation process.
