Zn3V2O7(OH)2(H2O)2 and Zn3V2O8 nanostructures: controlled fabrication and photocatalytic performance

摘要: Floriated like and nanobelt nanostructures of Zn3V2O7(OH)2(H2O)2 were successfully synthesized by a template-free hydrothermal route. The as-prepared floriated composed 2D nanosheets, which intercrossed with each other through self-assembly. influence the temperature on morphology photocatalytic activities products was systematically investigated. Significantly, this is first time that used as photocatalyst for organic pollutant degradation under UV light irradiation. Moreover, Zn3V2O8 porous could be formed viacalcination corresponding Zn3V2O7(OH)2(H2O)2. It found nanostructure still possessed pore sizes within about 4 nm. All these characteristics beneficial improvement activity. reaction constant (k) best quality three times sample prepared solid-state visible-light
