A Promoted Charge Separation/Transfer System from Cu Single Atoms and C3N4 Layers for Efficient Photocatalysis
Abstract
Establishing highly effective charge transfer channels in carbon nitride (C 3 N 4) for enhancing its photocatalytic activity is still a challenging issue. Herein, for the first time, the engineering of C 3 N 4 layers with single‐atom Cu bonded with compositional N (CuNx) is demonstrated to address this challenge. The CuNx is formed by intercalation of chlorophyll sodium copper salt into a melamine‐based supramolecular precursor followed by controlled pyrolysis. Two groups of CuNx are identified: in one group each of Cu atoms is bonded with three in‐plane N atoms, while in the other group each of Cu atoms is bonded with four N atoms of two neighboring C 3 N 4 layers, thus forming both in‐plane and interlayer charge transfer channels. Importantly, ultrafast spectroscopy has further proved that CuNx can greatly improve in‐plane and interlayer separation/transfer of charge carriers and in turn boost the photocatalytic efficiency. Consequently, the catalyst exhibits a superior visible‐light photocatalytic hydrogen production rate (≈212 µmol h−1/0.02 g catalyst), 30 times higher than that of bulk C 3 N 4. Moreover, it leads to an outstanding conversion rate (92.3%) and selectivity (99.9%) for the oxidation of benzene under visible light.

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.
