In recent years, research aimed at achieving carbon neutrality has gained attention, increasing interest in biomass utilization and the chemical conversion of carbon dioxide. This study investigates the dry reforming of ethanol obtained from biomass, where ethanol reacts directly with carbon dioxide to produce synthesis gas. Previously, we reported that adding Ag and Au to CuCeO2ZrO2, which exhibits activity for this reaction, improves both catalyst activity and product selectivity. In this study, focusing on the CuCeO2ZrO2 catalyst, we varied the raw materials for the CeO2 and ZrO2 supports and investigated their effects on activity and selectivity. Catalysts with high CeO2 content showed high values in ethanol conversion, CO yield and H2 yield, regardless of the preparation method. When the catalyst preparation method was changed, the catalyst prepared by the impregnation method showed higher activity and selectivity than the catalyst prepared by the sol-gel method.
