Embodiment Construction

[0009] 7.74g (32mmol) Na 2 MoO 4 2H 2 O dissolved in 25ml H 2 O, stirred until completely dissolved, then acidified with 20ml of 10% hydrochloric acid, then added 0.68g (3mmol) of SnCl 2 2H 2 O, the mixed solution immediately turned dark blue. After continuing to stir for half an hour, the mixed solution was placed in the air, and a large amount of dark blue octahedral crystals were obtained after a few days. Calculated by Mo, the yield is about 70%. Select suitable crystals directly from the mother liquor, and conduct X-ray single crystal diffraction after sealing the tube. Chemical formula H 750 Mo 154 Na 14 o 830 , chemical formula weight: 29132.62.

Abstract

The poly metal acid salt compound has molecular formula as Na14[MoVI126MoV28O462H14(H2O)68]íñca.300H2O, belongs to orthorhombic crystal system with space group as Cmca and single cell parameters as aú¢50.6844(4)ú¼bú¢56.3056(1)(cú¢30.6337(1)ú¼Vú¢87422.9(8)(3)ú¼Zú¢4. This product uses elementary huge-wheel ring shape as basic unit and Oxygen Bridge to link into two-dimension layer structure of calandria form, which can be used in adsorption material or solid fuel cell.

Description

technical field [0001] The invention belongs to the field of polyoxometalate applied materials, and relates to a class of polyoxometalate with special structure and its synthesis. Background technique [0002] Metal-organic composite nanopolymer materials with nanoscale pores and their applications are a new research field in the past two years. In recent years, research related to it has rapidly developed into a new comprehensive research field, and it is believed that it will play a vital role in the development of science in this century. This type of material has many special properties, and has shown attractive application prospects in the development of new functional materials such as selective catalysis, molecular recognition, and reversible host-guest molecule (ion) exchange. One of the most challenging fields of research in the chemistry and materials disciplines of the first century. [0003] The research on various nano-scale ultra-high core molybdenum (tungste...
