Performance and Stability of Corundum-type In₂O₃ Catalyst for Carbon Dioxide Hydrogenation to Methanol.

ABSTRACT: Carbon dioxide hydrogenation to methanol is a key chemical reaction to store energy in chemical bonds, using carbon dioxide as an energy sink. Indium oxide is amongst the most promising candidates for replacing the copper and zinc oxide catalyst, which is industrially applied for syngas mixtures but less idoneous for educts with carbon dioxide due to instability reasons. The polymorph of indium oxide and the operating conditions remain to be optimized for optimal and stable performance. Indium oxide catalysts containing different rhombohedral and cubic phase ratios were synthesized using a solvothermal method and evaluated in an ideally mixed gas phase reactor. The pure rhombohedral catalyst shows the best performance in terms of yield to methanol, selectivity, and stability. The phase sta
