Direct CO2 hydrogenation to ethanol over supported Co2C catalysts: Studies on support effects and mechanism
Abstract
Direct CO 2 hydrogenation to ethanol is one of the promising and emerging routes for the transformation of CO 2 into value-added chemicals, but it remains a major challenge because of low ethanol selectivity and catalytic stability. In this work, Na-promoted cobalt catalysts supported on different materials (Al 2 O 3 , ZnO, AC, TiO 2 , SiO 2 , and Si 3 N 4 ) were evaluated to elucidate the effects of supports. The SiO 2 - and Si 3 N 4 -supported catalysts exhibited efficient generation of ethanol with 18% CO 2 conversion and 62% selectivity in the alcohol distribution at 250 °C, whereas CH 4 was predominantly produced on other supported catalysts. Characterization results indicated that the Co 2 C active phase only remained intact on SiO 2 and Si 3 N 4 supports during reaction and exhibited excellent durability for 300 h, which was attributed to the existence of a strong metal–support interaction (SMSI) obtained by Si[sbnd]O[sbnd]Co bond formation. In situ DRIFTS results revealed that CO produced on Co 2 C inserted into CH x intermediates to form ethanol. Moreover, CO as the reactive intermediate could induce the regeneration and reconstruction of decomposed Co 2 C on the surface for catalytic sustainability. © 2019 Elsevier Inc.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
