摘要：

As the misuse and overuse of tetracycline (TC) exaggerates the pollution of aqueous solution, it is imperative to explore an efficient and cost-effective approach for the removal of TC in the aqueous solution. Photocatalysis is a green and sustainable chemical technique because of its utilization of solar energy. From the view of practical application, it is significant to design a highly efficient, stable, eco-friendly and economical photocatalyst. In this work, CuBi₂O₄/g-C₃N₄ p-n heterojunctions with different contents of CuBi₂O₄ (10-90 wt.%) were prepared via a facile calcining method. The CuBi₂O₄/g-C₃N₄ heterojunctions as photocatalysts exhibit superior photocatalytic activity in the degradation of TC compared with pristine CuBi₂O₄ and g-C₃N₄. The optimum photoactivity for 70 wt.% CuBi2O₄/g-C₃N₄ is up to 4 and 6 times higher than that of CuBi2O4 and g-C₃N₄, respectively. The enhanced photocatalytic activity could be attributed to p-n junction photocatalytic systems, which effectively promoted charge carriers separation and transfer. It is anticipated that the design of CuBi₂O₄/g-C₃N₄ could offer more ideas concerning the construction of g-C₃N₄-based heterojunction photocatalysts with low cost and high efficiency to relieve the urgent environmental deterioration.
