Abstract
- Graphical abstract Abstract In the present work, a novel porous, and chemically stable amine-based covalent organic polymer (POP-1) was designed and synthesized under solvothermal conditions. The porosity, crystallinity, chemical stability, electrochemical properties, and diffuse reflectance of POP-1 were investigated via N 2 sorption experiment, power X-ray diffraction, thermogravimetric analysis, cyclic voltammetry, and ultraviolet visible near infrared spectrometry, respectively. POP-1 exhibits good chemical stability in both acidic and alkaline aqueous solutions, as well as in organic solvents. Undoped POP-1 can be directly used as a photocatalyst for rhodamine B irradiation degradation under light-emitting diode and natural light. The E a of POP-1 for RhB degradation is 82.37 kJ/mol. Furthermore, POP-1 can be reused as a catalyst in RhB degradation without degraded catalytic activity. [ABSTRACT FROM AUTHOR]
