Highly Selective Conversion of Carbon Dioxide to Lower Olefins
Abstract
Conversion of CO 2 to value-added chemicals has been a long-standing objective, and direct hydrogenation of CO 2 to lower olefins is highly desirable but still challenging. Herein, we report a selective conversion of CO 2 to lower olefins through CO 2 hydrogenation over a ZnZrO/SAPO tandem catalyst fabricated with a ZnO-ZrO 2 solid solution and a Zn-modified SAPO-34 zeolite, which can achieve a selectivity for lower olefins as high as 80–90% among hydrocarbon products. This is realized on the basis of the dual functions of the tandem catalyst: hydrogenation of CO 2 on the ZnO-ZrO 2 solid solution and lower olefins production on the SAPO zeolite. The thermodynamic and kinetic coupling between the tandem reactions enable the highly efficient conversion of CO 2 to lower olefins. Furthermore, this catalyst is stable toward the thermal and sulfur treatments, showing the potential industrial application.

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.
