Catalysts for CO2-to-methanol are typically evaluated in a single-pass regime using pure CO2streams. In a practical process however, CO shall be present as a feed impurity or as a recycled byproduct. Herein, the sensitivity to CO was evaluated on In2O3 catalysts in bulk, supported, or metal-promoted forms, using cycle experiments with variable CO2 and CO contents at H2/(CO + CO2) = 4. The methanol productivity was decreased (−20-−40 %) on all catalysts except In2O3/monoclinic-ZrO2, the activity of which was boosted by 10 %. In-depth characterization of the catalysts uncovered controlled formation of oxygen vacancies and resistance to sintering as the main reasons for the activation of the latter and an interplay of CO/H2O-induced sintering and CO inhibition as the origin of performance loss. Focusing on the most representative systems, operation protocols were explored to maximize their methanol yield. We emphasize that assessment with hybrid CO2-CO feeds is key for the design of industrially-viable catalysts for sustainable methanol production.
In2O3 catalysts promoted with 0.75 wt.% Pd or 1 wt.% Ni were produced by coprecipitation (CP, catalysts noted as Pd-In2O3 and Ni-In2O3) and dry impregnation (DI, catalysts coded as Pd/In2O3 and Ni/In2O3) [20]. For CP, In(NO3)3·7H2O (3.5 g) and Pd(NO3)2.5H2O (0.025 g, Sigma-Aldrich) or Ni(NO3)2·6H2O (0.056 g, Sigma-Aldrich, >97 %) were dissolved in deionized water (50 cm3). A solution of Na2CO3 (10 g) in deionized water (100 cm3) was added under magnetic stirring (500 rpm) until pH 9.2. The resulting slurry was aged for 1 h. Thereafter, it was diluted with additional deionized water (50 cm3) and the precipitate was recovered by high-pressure filtration, washed three times with deionized water (1.25 L each time), dried in a vacuum oven (2 kPa, 323 K, 12 h), and calcined at 573 K (2 K min−1) for 3 h in static air. Upon DI, Pd(NO3)2.5H2O (0.095 g) or Ni(NO3)2·6H2O (0.21 g) dissolved in deionized water (0.4 cm3) were added to In2O3 (4 g, calcined at 573 or 773 K in the case of palladium or nickel promotion, respectively) upon mechanical stirring. After drying in a vacuum oven (2 kPa, 323 K, 12 h), calcination was conducted at 573 K (2 K min−1) for palladium-containing samples and at 623 K for those comprising nickel for 3 h in static air.
