Figure 6. Practicality of the reactions and mechanistic studies. (A) Recycle experiments of TANB-Py-COF; (B) PXRD patterns of TANB-Py-COF before and after six consecutive photocatalytic cycles; (C) FT-IR patterns of TANB-Py-COF before and after six consecutive photocatalytic cycles; (D) Artificial photosynthesis with different radical scavengers; (E) EPR analysis. COF: Covalent organic framework; PXRD: powder X-ray diffraction; FT-IR: fourier transform infrared; BHT: butylated hydroxytoluene; TEMPO: tetramethylpiperidine N-oxyl.
