  通过熔盐辅助组装方法设计钼酸铋光催化剂的尺寸和晶体结构

  摘要：

  摘要 在这项工作中，研究了一种简便的熔盐辅助组装策略，以实现钼酸铋光催化剂的可控合成，包括 Bi2MoO6、Bi6Mo2O15、Bi4MoO9 和 Bi14MoO24。通过调节熔盐合成时间，可以有选择地、高效地实现钼酸铋从Aurivilius型到萤石型的转变。观察到随着材料中 Bi/Mo 摩尔比（从 3 到 14）的增加，钼酸铋样品在吸收带中表现出明显的红移，表明带隙减小。因此，在可见光照射下，萤石型 Bi14MoO24 样品的 TC 去除光催化活性高于 Bi2MoO6、Bi6Mo2O15 和 Bi4MoO9 样品。此外，在这项工作中系统地研究了Aurivilius型和萤石型之间的相变机制以及它们的钼酸铋的能带结构。该研究不仅为不同维度和结构的钼酸铋的可控合成提供了一种新策略，而且为设计和优化先进的钼酸铋基光催化剂用于能量收集和环境修复开辟了新途径。

  Four low-temperature phases with compositions Bi10Mo3O24, Bi6Mo2O15, Bi14Mo5O36 and Bi8Mo3O21 have been prepared by the n-butylamine wet synthesis method. They have been characterized by powder X-ray diffraction and transmission electron microscopy, mainly by selected area electron diffraction. The four phases present a close structural relationship and a common basic fluorite-type structure and are members of a homologous series of phases with general formula Bi2n+4MonO6(n + 1), being n = 3, 4, 5 and 6, respectively. The matrices relating their superstructures and the basic fluorite type unit cell are given, as well as a general one for the whole series. The conductor behavior of these phases is characterized by impedance spectroscopy being all these materials very good ionic conductors. (c) 2006 Elsevier Inc. All rights reserved.
