| The present invention discloses a method for gamma irradiation enhanced hydrophilicity of covalent organic frameworks(COF). After the covalent organic framework is processed by gamma irradiation treatment, the hydrogen production rate increases significantly. Fourier transform infrared spectroscopy (FTIR) detected the hydroxyl groups in the covalent organic framework after gamma irradiation treatment and measured the contact angle. That is, gamma irradiation treatment improved the wettability of the COF, and XPS studies showed that chemical reaction changes occurred on the surface of the COF. |
