Semiconductor-based heteronanostructures with the high carriers-flow steering and high activity and stability in the visible-light-driven multicomponent photocatalytic system have been of great concern due to its long-standing demand in the wide application of environmental protection and energy conversion. However, the construction of ternary-component nanocrystals usally undergos multiple complex steps to restrict its application. In the work, we successfully report the facile design and synthesis of a novel double Z-scheme Zn-3(VO4)(2)/Zn2V2O2/ZnO ternary heteronanostructure system (THS) via self-phase transition with heating on basis of the Zn-3(OH)(2)V2O7 center dot 2H(2)O precursor in a low-cost microwave hydrothermal assistant, which exhibited excellent photocatalytic performances. In this case, the employment of Zn-3(OH)(2)V2O7 center dot 2H(2)O as the heteronanostructure precursor is the key for fabricating the THS material, which not only boosted the interaction with its structure and but also maintained the mesoporous nanosheet structure. It has been proved that Zn-3(OH)(2)V2O2 center dot 2H(2)O firstly lost it H2O and then the partial Zn-3(VO4)(2) underwent the self-phase transition process to produce Zn2V2O2 and ZnO (Zn-3(OH)(2)V2O2 center dot 2H(2)O -> Zn-3(VO4)(2) -> Zn2V2O2 + ZnO), which obtained the double Z-scheme THS. Accordingly, the interfacial-dominated photocatalysis reactivities such as the removal of phenols and dyes were used as ideal experiments to verify the responsibility of the constructed double Z-scheme THS material that was equipped with the narrow band gap, intimate contact interface, the wide visible light absortion and more efficient charge transfer and separation for high visible-light photocatalytic reactivity and stable cycling. PL spectra, radicals trapping experiments and ESR tests confirmed that the nontraditional transport of photoinduced h(+) and e(-) caused by double Z-scheme mechanism played an important role in the efficient removing the target pollutants. Such a synthetic approach maybe render double Z-scheme THS to advance the development for largescale applications of the hetero-transition metal vanadates.
