Abstract
Cu-Ce-O and Fe-Ce-O composite catalysts have been synthesized by solution combustion route. It is found that the copper oxide and iron oxide phases are well dispersed on CeO2 support by this method. All the composite catalysts have been tested for heterogeneous decomposition of H2O2 in neutral solution. The compensation effects have been observed on the composite catalysts. They are correlated to different surface active sites available on dispersed copper oxide and iron oxide phases in the respective composites. The kinetic data clearly show that there is a transformation from dispersed CuO to crystalline CuO with increased copper loading in Cu-Ce-O composite while iron oxide has always been present in highly dispersed state in Fe-Ce-O composite. The XRD and EPR data pertaining to CuO (20 mol%)-CeO2 and Fe2O3 (20 mol%)CeO2 composite samples are presented.
