Photocatalytic Reduction of CO2 to CO in the Presence of H2 or CH4 as a Reductant over MgO
Abstract
MgO exhibits activity for the reduction of CO 2 to CO under photoirradiation in the presence of H 2 or CH 4 as a reductant, although MgO is an insulating material. The present study clarified the mechanism of the CO 2 photocatalytic reduction in the presence of H 2 or CH 4 over MgO. The electron paramagnetic resonance (EPR) spectra show that a CO 2 molecule adsorbed on MgO was activated to a CO 2 - radical under photoirradiation. In addition, it was confirmed by photoluminescence that new acceptor level built up between the valence band and the conduction band of MgO on CO 2 -adsorbed MgO. The CO 2 - radical was reduced to a surface bidentate formate or a surface bidentate acetate by H 2 or CH 4 in the dark, respectively. The surface bidentate formate anchors on MgO as a photoactive species and reduces CO 2 in the gas phase to CO since the CO 2 photocatalytic reduction proceeded over MgO absorbing HCHO or CH 3 CHO and only 12 CO was formed in the presence of 12 CO 2 over MgO modified by a 13 C-labeled formate under irradiation. The active species was generated from the side-on adsorption-type bidentate carbonate selectively, although the two types of bidentate carbonates were detected by Fourier transform infrared (FT-IR) spectroscopy. On the other hand, the role of the surface bidentate acetate is under discussion. It is the first report that the substrate-modified insulating material exhibits activity in the CO 2 photocatalytic reduction.

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.
