A new triazine-based covalent organic polymer for efficient photodegradation of both acidic and basic dyes under visible light

Abstract

A new triazine-based covalent organic polymer (named COP-NT) which showed high catalytic activities for degradation of acidic and basic dyes was synthesized. The structure characteristics were fully investigated, which featured large specific surface area, homogeneous porosity, strong visible light absorption, excellent thermal stability and semiconductor performance. The as-prepared COP-NT exhibits good chemical stability both in acidic and alkali aqueous solutions, which could be used as efficient photocatalyst for degradation of methyl orange (MO), rhodamine B (RhB) and methylene blue (MB). The Ea values for degradation of MO, RhB or MB are 9.40 kJ/mol, 30.94 kJ/mol or 17.54 kJ/mol, respectively. Furthermore, COP-NT showed excellent reusability in degrading all above dyes without obvious performance decay.
