Synthesis, Characterization, and Properties of a New Type of Heteropoly Acids and Supramolecular Compounds

Abstract

In this article, the method of stepwise acidification, gradually charging and ion exchange was employed for synthesizing tungsten vanadium aluminum heteropoly acid catalysts and heteropoly acids-glycine supramolecules. These novel products were further characterized through chemical analysis, IR, UV-Vis absorbance spectra, and X-ray diffraction analysis. The catalytic properties of these supramolecules were tested and prove the superior catalytic activity than most existing heteropoly acids.

Keywords:

• Catalytic activity
• glycine
• heteropoly acid
• supramolecule
