Synthesis, Characterization and Catalytic Performance of Ceria-Supported Cobalt Catalyst for Methane Dry Reforming To Syngas

Synthesis, Characterization and Catalytic Performance of Ceria-Supported Cobalt Catalyst for Methane Dry Reforming To Syngas

In this study the synthesis, characterization and catalytic performance of CeO2 (Ceria) supported Co catalyst was investigated. First, the ceria was synthesized by direct thermal decomposition of Ce(NO3)3.6H2O and subsequently impregnated with 20 wt.% Co using aqueous solution of Co(NO3)2.6H2O as a...

TP Chemical technology In this study the synthesis, characterization and catalytic performance of CeO2 (Ceria) supported Co catalyst was investigated. First, the ceria was synthesized by direct thermal decomposition of Ce(NO3)3.6H2O and subsequently impregnated with 20 wt.% Co using aqueous solution of Co(NO3)2.6H2O as a precursor.
