Preparation of SiO2@CN/BTO membrane and its enhanced photocatalytic performance

Abstract

The SiO2@CN/BTO heterojunction membrane were prepared by electrostatic spinning technique. The fluffy banded g-C3N4 and layered Bi3Ti4O12 were loaded on SiO2 fibers, which enhanced the photocatalytic activity for tetracycline (TC). The experimental results showed as follows: the degradation efficiency was 96% within 150 min, and the degradation efficiency did not decrease after four repetitions. The reason may be the excellent specific surface area and the heterojunction structure between g-C3N4 and Bi3Ti4O12, which improved the electron-hole separation efficiency. This result has greater potential for future degradation drug studies.
