Mechanism of 2,4-dinitrophenol photocatalytic degradation by ζ-Bi2O3/Bi2MoO6 composites under solar and visible light irradiation.

Highlights: [•] Facile method: The catalysts were synthesized by facile hydrothermal method without any templates. [•] Good properties: 20BBM exhibits the best property of degradations of 2,4-DNP among the reported catalysts. [•] Effect of H2O2: H2O2 improving the activity of photodegradation of 2,4-DNP is firstly demonstrated. [•] New mechanism: New photocatalytic mechanisms for the heterostructured composites are proposed. [Copyright &y& Elsevier]
