Synthesis, Characterization and Catalytic Activity of New Layered Microporous Material-FeW11NiO39Pillared Anion Clay
Abstract:
Layered double hydroxides pillared by tungstoferrate heteropolyanion with substituted transition metal Ni, ZnAl-FeW11Ni, has been synthesized by means of hydrothermal ion exchange method. Powder X-ray diffraction shows that the anionic clay precursor possesses a regular layered structure and a good crystallinity, and the pillared derivative has 2θ of 4.96° and gallery height of 1.325 nm. IR spectra indicate that the vibrational frequency and band shape of heteropolyanion existing in the layered regions of anionic clay are similar to those of the authentic heteropoly salt. So we can draw the conclusion that the Keggin structure of the gallery heteropoly anions is maintained. ESR results indicate that the heteropolyainons are of ordered arrangement in layered clay region.Tests show that the new pillared compound has a higher catalytic activity than that of anionic clay and heteronoly salts for dioctyl phthalate synthesis.
