P and Cu Dual Sites on Graphitic Carbon Nitride for Photocatalytic CO2Reduction to Hydrocarbon Fuels with High C2H6Evolution

Wang, Gang, Chen, Zhe, Wang, Tao, Wang, Dingsheng, Mao, Junjie·2022·Angewandte Chemie International Edition

Abstract

The light‐driven CO 2 reduction to multi‐carbon products is especially meaningful, while the low efficiency of multi‐electron transfer and sluggish C−C coupling greatly hinder its development. Herein, we report a photocatalyst comprising of P and Cu dual sites anchored on graphitic carbon nitride (P/Cu SAs@CN), which achieves a high C 2 H 6 evolution rate of 616.6 μmol g−1 h−1 in reducing CO 2 to hydrocarbons. The detailed spectroscopic characterizations identify the formation of charge‐enriched Cu sites, where the isolated P atoms serve as hole capture sites during photocatalysis. Theoretical simulations combined with in situ FTIR measurement reveal a kinetically feasible process for the formation of C−C coupling intermediate (*OC−COH) and confirm the favorable production of C 2 H 6 on the P/Cu SAs@CN photocatalyst. This work offers new insights into the photocatalyst design with atomic precision toward highly efficient photocatalytic CO 2 conversion to high value‐added carbon products.

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.
