Abstract

A novel carbon modified Co₃O₄/BiVO₄ p-n heterojunction photocatalyst (Co₃O₄/BiVO₄/C) is prepared via one-step method. The Co₃O₄/BiVO₄/C photocatalyst is characterized by SEM, Raman, UV–vis DRS, electrochemical performance analysis and so forth. In addition, the optimum activity of the Co₃O₄/BiVO₄/C p-n heterojunction is higher than that of pure Co₃O₄ and BiVO₄ for the degradation of tetracycline under visible light. The improved photocatalytic property could be ascribed to the enhanced light absorption and the facilitated separation of photogenerated charge carriers through forming a p-n heterojunction. Furthermore, the Co₃O₄/BiVO₄/C has superior magnetic properties, recyclability and stability, which is conducive to practical application.
