摘要：

The adsorption of ammonia on an alumina supported copper catalyst and on unsupported copper powder was studied by diffuse reflectance FTIR spectroscopy in the temperature range 423-643 K. Bands in the region between 1950 and 2350 cm-1 were identified as being due to surface-bound azides. These species are suggested to be possible precursors in the copper nitride formation observed earlier. © 1990 J.C. Baltzer A.G. Scientific Publishing Company.
