摘要：

Since the misuse and overuse of tetracycline (TC) increase the pollution of aqueous solution, it is highly desirable to develop highly effective, stable, eco-friendly, economical, and facile photocatalysts for the photocatalytic degradation of TC in an aqueous solution. Herein, we designed and synthesized a highlyefficient CoO/g-C₃N₄ p�n heterojunction via a facile solvothermal method. The experimental results demonstrated that after the coupling of CoO with g-C₃N₄, CoO nanoparticles were uniformly distributed on the surface of wrinkled g-C3N4 layers not only to readily form a p�n heterjunction, but also to avert the aggregation; and the CoO/g-C₃N₄ p�n heterojunction photocatalysts exhibited superior visible-light photocatalytic activity and stability for the removal of TC. The high photocatalytic activity could be attributed to the generation of an internal electric field induced by the p�n heterojunctions, effectively promoting the separation of photoinduced charge.
