摘要:A method of making a covalent organic framework includes continuously feeding a first precursor and a second precursor to a flow reactor; heating, and mixing the first and second precursors; nucleating and growing the covalent organic framework; and continuously outputting the covalent organic framework from the third section of the flow reactor. A photo-reactor for treating contaminated water includes: a light source; an enclosed channel around the light source; a cover comprising one or more lights illuminating the enclosed channel; and a covalent organic framework cased within the enclosed channel, where the covalent organic framework is photo-catalytically active for degrading a contaminant in the contaminated water so as to produce treated water. A method of treating contaminated water includes feeding the contaminated water to the photo-reactor and contacting the contaminated water with the covalent organic framework.

摘要:The present invention provides use of an ionization radiation source in preparation of a porous crystalline material, and a method for preparing a MOFs material and a COFs material. In the present invention, the ionization radiation source is used for preparing the porous crystalline material; under the irradiation of the ionization radiation source, the porous crystalline material (MOFs, COFs) can be synthesized in an extremely short time, wherein the ionization radiation source is used for providing energy required in a reaction for preparing the porous crystalline material. The preparation process does not need heating, so that energy consumption is reduced and a high-pressure system is avoided. The aforementioned preparation method is simple, low in instrument and equipment cost, and thus is a environmentally friendly and extremely low-cost synthesis method.
