The invention discloses a honeycomb CTFs@GC airgel with controllable pore size, a preparation method and application thereof. At normal temperature and pressure, graphitic carbon (GC) is used as the adsorption substrate to construct aerogels, covalent triazine frameworks (CTFs) are loaded on the graphitic carbon as photocatalysts, and the pore size is controlled by polyvinyl alcohol (PVA) crosslinking agent , forming honeycomb CTFs@GC airgel. The GC and CTFs in the airgel serve as adsorption sites and photocatalytic sites respectively, and have ultra-high adsorption and photocatalytic degradation rates for aromatic pollutants, and can be adjusted by The chain length of the PVA molecule realizes the adjustment of the pore size of the airgel to deal with complex water pollution conditions. The honeycomb-type CTFs@GC airgel with controllable pore size of the present invention is not only synthesized by a green and environmentally friendly method, but also has ultra-high catalytic degradation performance for aromatic pollutants. The airgel after use is easy to recycle and reuse, and can be used in the environment Pollution control, chemical industry and other related fields. |
