Dispersion and reactivity of copper catalysts supported on Al2O3-ZrO2

Article Abstract:

The characterization of CuO/Al2O3-ZrO2 catalysts by powder X-ray diffraction (XRD), electron spin resonance (ESR), temperature-programmed reduction (TPR), and temperature-programmed desorption (TPD) of CO2 and NH3 is reported. The dispersion of copper supported on Al2O3-ZrO2 is estimated as a function of copper loading and the changes in structure of the copper phase is identified with increased active-phase loading.

Characterization and catalytic functionalities of copper oxide catalysts supported on zirconia

Article Abstract:

The characterization and preparation of a series of zirconia supported copper oxide catalysts with varying copper loadings by using impregnation method are presented. The activity of the catalysts increases up to 2.7 wt% and decreases at higher loadings and CuO/Zr[O.sub.2] catalyst is found to be better than other copper catalysts under similar conditions.

Characterization and reactivity of copper oxide catalysts supported on TiO2-ZrO2

Article Abstract:

A series of copper catalysts supported on TiO2-ZrO2 with copper loading varying from 1.0 to 21.6 wt% is prepared by a wet impregnation method. N2O decomposition is a valuable method for measuring dispersion of Cu on TiO2-ZrO2.
