Highly Active ZnO-ZrO2 Aerogels Integrated with H-ZSM-5 for Aromatics Synthesis from Carbon Dioxide
Abstract
Bifunctional catalysis coupling CO 2 to methanol and methanol to hydrocarbons is a promising strategy for the direct hydrogenation of CO 2 into high-value chemicals. However, bifunctional catalysts suffer from low productivity due to the inertness of CO 2 and high activation energy of C–C coupling. Herein, we report a highly active bifunctional catalyst consisting of a ZnO-ZrO 2 aerogel and zeolite H-ZSM-5 for the hydrogenation of CO 2 into aromatics with 76% selectivity at a single-pass CO 2 conversion of 16%. The selectivity of CH 4 is lower than 1% at the same time. The space–time yield of aromatic hydrocarbons is as high as 0.24 g g oxide –1 h –1 under the reaction conditions of 340 °C and 40 bar over ae -ZnO-ZrO 2 /H-ZSM-5 catalyst, which outperforms the previously reported catalysts, including modified Fischer–Tropsch catalysts. We demonstrate that the ZnO-ZrO 2 aerogel catalyst, which is prepared by a combined sol–gel and subsequent supercritical drying method, not only possesses high surface area but also provides large amounts of oxygen vacancies. The formation rate of the methanol intermediate over ZnO-ZrO 2 is dominated by the total amount of oxygen vacancies. Moreover, the stable performance of the bifunctional catalyst under industrially relevant conditions suggests promising prospects for industrial applications.

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.
