Abstract

The experimental results on the characterization of Cu-based catalysts supported on various supports (ZSM-5, Al2O3, ZrO2, MgO, TiO2) are presented using the techniques of x-ray diffraction (XRD), temperature-programmed reduction (TPR) and electron magnetic resonance (EMR). The catalysts have been tested upto 300 0C for the conversion of methanol to H2. TPR and EMR studies show the presence of both crystalline CuO and CuO finely dispersed and incorporated into the supports. A two-step reduction of the finely dispersed CuO to Cu(0) occurs near 160-170 0C whereas crystalline CuO reduces at higher temperatures(different for different supports). The observation of Cu(2+) EMR signal even in the used samples suggests the importance of finely dispersed CuO in the catalytic activity.
