Synthesis of bipyridine-based covalent organic frameworks for visible-light-driven photocatalytic water oxidation
Abstract
Abstract Covalent organic frameworks (COFs) with band gap engineering characters are attractive organic semiconductors. Although several COFs are being utilized for photocatalytic H2 production and CO2 reduction, few of them can realize the challenging water oxidation under visible light. Herein, we present the visible-light-driven photocatalytic water oxidation on bipyridine-based COFs (Bp-COF), which was synthesized through the Schiff base condensation reaction. Bp-COF displays impressive visible-light-driven water oxidation activity with O2 evolution rate of 152 μmol g−1 h−1 after coordinating with Co2+. Furthermore, the Bp-COF could also enable photocatalytic H2 production under visible light. The unique photocatalytic performance of BpCo-COF for both water oxidation and proton reduction could be attributed to its excellent light harvesting property, appropriate energy band structure, high porosity and wettability as well as coordinated cobalt for photocatalytic water splitting. This work demonstrates the potential of COFs as semiconductors for photocatalytic solar fuels conversion.

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.
