Abstract

This study presents the $CO_2$ methanation reaction on Pt catalysts for reducing the amount of $CO_2$, one of greenhouse gases. The AlO(OH) of $Al_2O_3$precusor was used as a support via a thermal treatment and the Pt was used as an active metal. In XRD results, it was confirmed that the Pt was well dispersed and the support existed as the gamma $Al_2O_3$phase. The $Pt/Al_2O_3$ catalyst calcined at $600^{\circ}C$ showed the highest conversion efficiency and selectivity.
