ZrO2-x modified Cu nanocatalysts with synergistic ...

2021-1-1 · A ZrO 2−x modified Cu nanocatalyst was prepared via a facile in situ structural transformation from hydrotalcite precursors.. This Cu-based catalyst was employed for the vapor-phase hydrogenation of dimethyl oxalate to ethylene glycol. • The optimal catalyst exhibits an excellent ethylene glycol yield (99.5%) and a high turnover frequency value (42.4 h −1).

Structure–Activity–Selectivity Relationships in Propane ...

2020-7-6 · A few years ago, we introduced alternative-type bulk ZrO2-based catalysts for nonoxidative propane dehydrogenation (PDH). Currently, they belong to the state of the art catalysts owing to their environmental compatibility, high activity, propene selectivity, and durability. However, the structure–activity–selectivity relationships are still not appropriately understood. To close such gaps ...

Strong Electronic Oxide–Support Interaction over …

2020-11-23 · In2O3/m-ZrO2 exhibits methanol selectivity up to 84.6% with a CO2 conversion of 12.1%. Moreover, at a wide range of temperatures, the methanol yield of In2O3/m-ZrO2 is much higher than that of In2O3/t-ZrO2 (t-: tetragonal), which is due to the high dispersion of the In–O–In structure over m-ZrO2 as determined by in situ Raman spectra.
