Preparation of PANI/COF/ BiOBr composites and its photocatalytic degradation of organic compounds
View through CrossRef
PANI/COF/BiOBr catalysts were synthesized by hydrothermal method basing on Schiff base reaction. The composites were characterized by XRD, SEM, etc., and at the same time, the photocatalytic property and degradation mechanism of PANI/COF/ BiOBr catalysts were studied by degrading organic simulated dyes. The experimental results showed that the main structure of PANI/COF/BiOBr composite was flower ball structure with BiOBr main crystal type of tetragonal phase, and the degradation rates of PANI/COF/BiOBr were 1.44, 1.55 and 1.47 times of pure BiOBr for Rhodamine B, methylene blue and tetracycline hydrochloride, respectively. The free radical quenching experiment showed that h+ and e- were the most active species in the photocatalytic process.
