Abstract: sp -Carbon-linked covalent organic framework (NP-COF), with hexagonal and porous structure,
was synthesized from N,N'-p-acetonitrile benzene-3,4,9,10-naphthalimide and 1,3,5-tris(p-formylphenyl)
benzene monomers by solvothermal method. The structure and morphology of NP-COF were characterized
by XRD, FTIR, 13 CNMR, XPS, N 2 adsorption-desorption, SEM, TEM, EDS and HRTEM. Then, its
photoelectric performance was investigated by photoluminescence studies. Furthermore, the photocatalytic
ability of NP-COF for oxygen evolution of H 2O under visible light irradiation was evaluated and the reaction
mechanism was speculated. The results indicated that NP-COF was an excellent semiconductive catalyst with
good light absorption capacity and certain advantages of carrier generation and migration. It could
efficiently catalyze the oxidation reaction of H 2O molecules under visible light irradition. The NP-COF,
under the condition of Co(NO 3) 2•6H 2O as cocatalyst, with an average oxygen evolution rate of 344
μmol/(g·h), presented higher efficiency in oxygen evolution catalysis in comparison to other covalent
organic framework photocatalysts previously reported under same conditions.
