| description | A novel 1D/2D Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub>–BiOI heterojunction photocatalyst with high-quality interfaces was synthesized through a hydrothermal method by using Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> nanorods and KI as raw materials. Two-dimensional (2D) BiOI nanosheets uniformly and vertically grow on the 1D porous Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> rods. Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub>–BiOI heterojunctions exhibit better photocatalytic activity than pure Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> nanorods and BiOI nanosheets. Cr(VI) (30 mg/L), MO (20 mg/L) and BPA (20 mg/L) can be completely degraded in 8–15 min. The superior photocatalytic performance of 1D/2D Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub>–BiOI heterojunction is ascribed to the synergistic effects: (a) vertical 2D on 1D multidimensional structure; (b) the formation of the Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub>–BiOI p–n heterojunction; (c) high-quality interfaces between Bi<sub>2</sub>O<sub>2</sub>CO<sub>3</sub> and BiOI. |
