概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)

In this project, several doped oxide catalysts were synthesized and tested for CO₂ hydrogenation activity. 

実験 / Experimental

 The atomic level dispersion of dopant in the catalyst was confirmed using HAADF-STEM analysis using JEOL ARM-200F (HK-401).

結果と考察 / Results and Discussion

The In-TiO₂ doped oxide and Co-ZrO₂ doped oxide showed excellent activity for reverse water gas shift reaction. CO₂ conversion with high CO yield was obtained even under high pressure reaction conditions.The superior CO selectivity was attributed to the absence of nanoparticles in the catalyst.
