    摘要本论文旨在探究利用水热法合成钨酸铋(Bi2W06)材料的纳米结构，测试合成的材料的光催化性能，并对所合成材料的结构和形貌进行表征。论文的主要研究内容可以分为两个部分：
    (1)．钨酸铋(Bi2W06)纳米材料的制备、结构及其可见光催化性能的研究
    以硝酸铋(Bi(N03)3•5H20)和钨酸钠(Na2W04•2H20)作为起始反应物，用SDS、DTAB作为表面活性剂用水热法来合成纳米级钨酸铋。利用X-射线衍射(XRD)、扫描电子显微镜(SEM)和X-射线光电子能谱法(XPS)及荧光发射光谱测试对产物进行了表征。论文中测试了合成的钨酸铋纳米材料的可见光催化性能以及探讨改变其制备条件、是否焙烧对催化性能的影响。研究表明水热法合成的钨酸铋经焙烧具有较高的可见光催化活性，表明钨酸铋具有较好的应用价值。8401
    (2)．掺杂铁（Fe）及铜（Cu）的钨酸铋(Bi2W06)可见光催化剂的制备及性能研究
        水热法合成钨酸铋的过程中掺杂一定摩尔比的铁及铜，通过光催化性能检测对比其未掺杂的钨酸铋的光催化性能。论文中探讨掺杂哪种元素以及掺杂的量对钨酸铋的光催化性能有显著提高。

    Title  Preparation, structure and the study on the photocalytic properties of _ photocatalysts doped with Bi2W06_under visible light
    Abstract
    This paper aims to explore the nano-structure of Bi2W06 material which is created by Hydrothermal Synthesis, to test the photocatalytic properties of materials, and to characterize the structure and the feature of the  material. It can be mainly pided into two parts.
       (1) Preparation, structure and the study on the photocatalytic properties of photocatalysts of Bi2W06 nano material under visible light.
         Setting Bi(N03)3•5H20 and Na2W04•2H20 as the starting reactant, SDS and DTAB as surfactant, to compose the nanoscale Bi2W06 by Hydrothermal Synthesis. Characterize the product by using X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS), and fluorescence emission spectrum test. It is included in this paper that the test of the photocatalytic properties of the Bi2W06 nano material under visible light, as well as the discussion of the influence on the photocatalytic properties according to different preparation conditions, and with or without roasting. The research shows that hydrothermal synthetic Bi2W06, which has been roasted, possess the high photocatalytic activity under visible light
       （2）the study of preparation and properties of photocatalysts of Bi2W06 doped with Fe or Cu under visible light.
    Doping in  certain molar ration of Fe or Cu during the process of hydrothermal synthetic of Bi2W06, comparing the performance of the catalyst with the pure Bi2W06 through the light catalytic performance testing. It is discussed in this paper that which element and how much of it will promote the light catalytic performance of Bi2W06.
