摘要：BiOCl is a promising photocatalyst, but due to its weak visible light absorption capacity and low photogenerated electron-hole pair separation rate, its practical application is limited to a certain extent. In this study, a novel double Z-type heterojunction UiO-66-NH2/BiOCl/Bi2S3 catalyst was constructed to broaden visible light response range and promote high photogenerated hole-electron separation of BiOCl. Through its photocatalytic performance was evaluated by dissociating tetracycline (TC) and rhodamine B (RhB) in visible light. The optimal proportion of UiO-66-NH2/BiOCl/Bi2S3 hybrids exhibits the best degradation efficiency of visible light illumination (~ 93% in 120 min for TC and ~98% in 60 min for RhB). The synergistic effect of large visible light response range and the Z-Scheme charge transfer mechanism ensures the excellent visible photocatalytic activity of UiO-66-NH2/BiOCl/Bi2S3. It is proved that h+ and ·O2- are the main active substances in the photocatalysis process by active substance capture experiment and electron spin resonance (ESR) test. The intermediates and degradation processes were analyzed by HPLC-MS. This study proved that the new UiO-66-NH2/BiOCl/Bi2S3 photocatalyst has great application potential in the field of water pollution degradation and will provide a new idea for the optimization of BiOCl. ? 2024, The Authors.
