Abstract：This study focuses on the treatment of hydrochloric tetracycline by utilizing a rice husk derived bio-silica(BSi)supported TiO2 shell-core catalyst(BSi@TiO2)that offers both cost-effectiveness and high efficiency.By integrating this catalyst with dielectric barrier discharge plasma(DBDP)technology,a DB-DP-assisted catalytic reaction system was established.The results indicate that under the assistance of DB-DP,BSi@TiO2-72%achieved a tetracycline degradation rate of 78.42%,surpassing the combined degra-dation rates of standalone catalysis and discharge,thus demonstrating a significant synergistic effect be-tween BSi@TiO2 catalysis and DBDP discharge.The catalyst achieved an optimal balance between degra-dation performance and cost-effectiveness when the TiO2 loading was 36%.Furthermore,the experiments revealed that an increase in discharge voltage significantly enhanced the degradation efficiency,while high-er initial concentrations of tetracycline led to decreased degradation rates.Alkaline conditions further im-proved the degradation efficiency.This research provides valuable insights and references for the develop-ment of effective and non-toxic remediation techniques for antibiotic pollutants.
