Abstract

In 2 O 3 was prepared by using thermal decomposition of indium (III) nitrate hydrate at 300 °C for 3 h. The obtained crystals show a rectangular shape with highly porous morphology. The length of the rectangular In 2 O 3 is ranged from 40 to 80 nm with an average pore diameter of ca. 3.4 nm. Such prepared In 2 O 3 catalyst shows an obviously higher activity for reverse water gas shift (RWGS) than Ga 2 O 3 obtained at the same decomposition temperature. The result is in good agreement with the theoretical prediction, which shows that adsorbed CO 2 on In 2 O 3 surface is more highly activated than that on the Ga 2 O 3 surface. The present work confirms that In 2 O 3 is a promising catalyst for not only RWGS but also other CO 2 conversion reactions.
