Abstract
The application provides a kind of Rind-based modified Schiff base porphyrin porous material and its preparation method and application, belong to the photocatalytic technical field of organic porous material.The application uses tetra (4-aldehyde phenyl) porphyrin and Rind2NH2 as monomer, and connects structural unit by reversible imine bond to prepare Rind-based modified Schiff base porphyrin porous material.The Rind-based modified Schiff base porphyrin porous material of the application uses porphyrin as skeleton, and adjusts its catalytic performance by modifying the periphery of porphyrin with Rind group, so that its photocatalytic effect is as high as 98%-100%, and it can be recycled and used without pollution.Porous material is connected by imine bond to enhance its thermal stability, and its 5% thermal weight loss is 350-430 DEG C.In addition, the porous material has strong adsorption capacity, and its specific surface area is 79-369 m 2 / g, and the pore size is 0.6-2.5 nm.The preparation method of the application is simple, stable and environmentally friendly.
