Rapidly Degrading Tetracycline by Highly Selective Catalysis with Hydroxyapatite Nanowire

Hydroxyapatite nanowire (HAnW), a novel synthesized biocompatible material without any transition metals, was applied to catalytic degradation of antibiotics. Importantly, tetracycline (TC), a common drug, could be rapidly adsorbed and catalytically degraded by HAnW, and the removal reached 85% within 5 min at room temperature. The biocompatible hydroxyapatite nanowire (HAnW) prepared by the one-step hydrothermal method has a fantastic ability to activate peroxymonosulfate (PMS), and the produced •O2− and 1O2 can quickly and selectively degrade tetracycline (TC).
