Dependence of copper species on the nature of the support for dispersed CuO catalysts

Article Abstract:

Copper catalysts prepared by chemisorption-hydrolysis technique over silica (Cu/Si) and silica- alumina (Cu/SiAl) supports are studied to understand the role of the support on the nature and surface properties of the copper species stabilized on their surfaces. Results indicate that the deposition of copper by using the same 'chemisorption- hydrolysis' method resulted in different supported species if silica or silica-alumina are employed as support.

Experimental and modelization approach in the study of acid-site energy distribution by base desorption: Part I: Modified silica surfaces

Article Abstract:

The acid properties of pure and modified silica surfaces were examined in a study by 2-phenylethylamine (PEA) desorption in a thermogravimetric (TGA) apparatus. The chemical modification of the silica surface by enrichment with Al, Ti, or Zr justified the increase of acidity of the modified silica surfaces compared with that of pure silica.
