| description | Introducing oxygen vacancies (OVs) in BiOCl catalyst has been regarded as an effective strategy in broadening the narrow range of light response and enhance separation efficiency of photo-induced carriers. However, the commonly-used methods for OVs generation are mostly realized under relatively harsh conditions. Herein, spherical BiOCl microparticles with abundant OVs assembled from nanosheet were synthesized via a mild one-step hydrothermal method. In addition, the concentration of OVs can be simply regulated via adjusting the mount of additives. The as-prepared BiOCl-3 samples presented the most favorable photocatalytic properties in decomposing Rhodamine B (RhB) under visible light via the improved separation efficiency of photo-induced carriers by sufficient OVs and more active sites due to large specific surface area for physical adsorption and photocatalytic decomposition. The degradation ratio of RhB reaches approximately 100 % within 48 min under BiOCl-3 catalysis, and the RhB degradation ratio still maintained a ratio of 90 % after four consecutive cycles. This work provides a beneficial reference for facile generation and regulation of OVs in photocatalysts with highly photocatalytic performance. |
