Photocatalytic Oxidative Dehydrogenation of Ethane Using CO2 as a Soft Oxidant over Pd/TiO2 Catalysts to C2H4 and Syngas
Abstract
Using CO 2 as the soft oxidant for the oxidative dehydrogenation of ethane (ODE) is a potential advancement for ethylene production from ethane. However, the current ODE reaction is primarily operated at high temperatures (e.g., 873 K), and the development of alternative approaches for the ODE reaction under the mild conditions is still a challenge. Herein, we report a photocatalytic ODE using CO 2 as the oxidant over Pd/TiO 2 catalysts at room temperature. The presence of CO 2 significantly promoted the production of C 2 H 4 and syngas, and the 1% Pd/TiO 2 catalyst exhibited a C 2 H 4 production rate of 230.5 μmol/g cat ·h and syngas of 282.6 μmol/g cat ·h. Density functional theory (DFT) calculation verified that the intermediate energy level provided by Pd and the covalent bond in Pd–O stimulated the electron transfer, excitation, and separation. The photoinduced electron, hole, and isolate OH on the surface of TiO 2 played essential roles during the whole process. In addition, the possible reaction pathways of photocatalytic ODE with CO 2 were proposed on the basis of the experimental data and DFT calculation results.

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.
