摘要：
Mono-(Au, Pd) and bimetallic Au-Pd catalysts supported on Fe-modified ceria were synthesized and characterized by XRD, TEM, XPS, and TPR techniques. The effect of support preparation (impregnation or mechanochemical mixing) on the structural, electronic, reductive and catalytic properties of the catalysts for complete benzene oxidation was investigated. The best catalytic performance and the positive role of Pd deposition on already deposited gold was observed over bimetallic catalyst supported on prepared by impregnation Fe-Ce support. Complete conversion of benzene was achieved over the most active bimetallic catalyst at 200 degrees C. During the 24 h.stability test at 200 degrees C the activity remained constant.
