Tuning CO2 hydrogenation selectivity via metal-oxide interfacial sites
Open accessAbstract
Abstract CO2 hydrogenation over ZrO2-supported NiFe catalysts is investigated to illustrate the role of Fe in controlling the activity and selectivity, and to reveal the structure-function relationship between metal-oxide interfaces and catalytic selectivities. The Ni-ZrO2 interfaces and Ni-FeOx interfaces are identified as the most likely active sites for the methanation reaction and the reverse water-gas shift reaction, respectively, using combined in-situ and ex-situ characterization techniques. The reaction mechanisms of CO2 hydrogenation to CH4 on the Ni-ZrO2 interfacial sites and to CO on the Ni-FeOx interfacial sites are further revealed by combined in-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and density functional theory (DFT) calculations. Both experimental and theoretical results demonstrate that the binding energy of absorbed CO (*CO) is a key descriptor to predict CO2 hydrogenation selectivity: weak interaction (e.g., Ni-FeOx interfaces) promotes *CO desorption to increase CO selectivity, while moderate interaction (e.g., Ni-ZrO2 interfaces) facilitates further hydrogenation of *CO to produce CH4.

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.
