  • Topotactic synthesis and photocatalytic performance of one-dimensional ZnNb2O6 nanostructures and one-dimensional ZnNb2O6/KNbO3 hetero-nanostructures
    RSC Adv., 2014
    Co-Authors: Xingang Kong, Zhanglin Guo, Puhong Wen, Liyun Cao, Jianfeng Huang, Jie Fei, Fen Wang, Qi Feng
    Abstract:

    This paper introduces one-dimensional ZnNb2O6/KNbO3 hetero-nanostructures and one-dimensional ZnNb2O6 nanostructures. These nanostructures are synthesized via in situ topotactic structural transformation reaction using the tunnel structure K2Nb2O6 Filiform Crystal as precursor. Firstly, Zn2+ ions intercalate into K2Nb2O6 Crystal by exchanging K+ ions from the K2Nb2O6 Crystal with Zn2+ from Zn(NO3)2 or Zn(CH3COO)2 aqueous solution, to form two different Zn2+-exchanged samples, and then these Zn2+-exchanged samples topotacticly transform into one-dimensional ZnNb2O6/KNbO3 hetero-nanostructures and ZnNb2O6 nanostructures during heat-treatment. The formation reaction and structure of these samples were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), selected-area electron diffraction (SAED), and energy-dispersive spectroscopy (EDS). Photocatalytic experiments showed that one-dimensional ZnNb2O6/KNbO3 hetero-nanostructures and ZnNb2O6 nanostructures have excellent photocatalytic performance for the degradation of methylene blue (MB), rhodamine B (RhB), and methyl orange (MO).

    Abstract:

    Abstract A topotactic soft chemical process was used for the synthesis of one-dimensional AgNbO 3 nanostructures. Firstly, using a tunnel structure potassium niobate K 2 Nb 2 O 6 · n H 2 O Filiform Crystal as precursor, the K + in K 2 Nb 2 O 6 · n H 2 O were exchanged by an Ag + in the AgNO 3 water solution, forming Ag + ion-exchanged sample. Secondly, the Ag + ion-exchanged sample was heat-treated to obtain the perovskite AgNbO 3 by in situ topotactic structural transformation reaction. The one-dimensional nanostructured AgNbO 3 was characterized by XRD, FE-SEM, TEM, SAED, EDS and UV–vis diffuse reflectance spectra. The one-dimensional AgNbO 3 nanostructures were constructed from nanoCrystals arranged along [011]-Crystal axis and with predominantly exposed (100) facet. The samples were able to degrade MB under ultraviolet irradiation and catalyze water-splitting in aqueous solution under illumination of visible light.
