TiO2 microspheres and Bi2WO6 microflowers were fabricated by hydrothermal method and then in-situ deposited with AgCl particles to form a ternary AgCl/Bi2WO6/TiO2 (ABT) heterojunction. Compared with pure AgCl, Bi2WO6, and TiO2, with the mass ratio 4:1:4, ternary heterojunction exhibited the highest photocatalytic performance, achieving 99.4% removal efficiency of Rhodamine B (RhB) in 30 min. The improved degradation efficiency was ascribed to the formation of heterojunctions, which reduced the combination of photogenerated carriers and accelerated their separation and transfer.
