摘要
In this paper, a simple method was used to rapidly prepare MOF-808 with a large specific surface area and high stability. Bi2S3 and MOF-808 were used to design and synthesize high-stability Bi2S3/MOF-808 nanocomposites, which were then used for the photocatalytic degradation of antibiotic tetracyclines. The performance test results showed that the 0.7-808 composite material had good photocatalytic degradation performance for tetracycline under visible-light irradiation, and the degradation rate reached 80.8%, which was 3.21 times and 1.76 times that of MOF-808 and Bi2S3, respectively. This was mainly due to the high photocurrent response and photoluminescence of the Bi2S3/MOF-808 composite material. Therefore, the close contact of n-n Bi2S3/MOF-808 can transfer light-generated electrons and holes to improve the utilization efficiency of photogenerated charges, thereby greatly improving the photocatalytic reaction activity. Particle-capture experiments and ESR confirmed that ˙OH was the main active substance in the photocatalytic degradation.
