The fabrication of a p-n heterojunction structure is known to be a strategy for realizing efficient separation and migration of charges in photocatalysts to improve their photocatalytic activity. In this paper, a series of BiMoO/CuBiO p-n heterostructured photocatalysts were mechanochemically synthesized in-situ. The synthesized products were characterized by various techniques and evaluated for their photocatalytic capacities with photocatalytic degradation of ciprofloxacin under visible light irradiation, which qualitatively confirmed the synchronous formation of the binary heterojunction with matched band structure in a solid-state system. Compared with pristine BiMoO or CuBiO, the BiMoO/CuBiO p-n composites showed enhanced performance in photocatalytic degradation of ciprofloxacin (CIP), owing to the formation of p-n junctions and the subsequent enhancement in separation and migration efficiency of photogenerated carriers. Moreover, the BiMoO/CuBiO composites maintained good stability after four cycles of CIP photodegradation. Based on the obtained results, a possible photocatalytic mechanism for the as-synthesized BiMoO/CuBiO composites was proposed.
