Recent advances in pillaring of layered double hydroxides by polyoxometalate anior

<正> Since the early 1980s, many isopoly and heteropoly compounds with different compositions and structures have appeared continuously. As a result a noticeable field——polyacid chemistry——has gradually formed. In this field, we have systematically carried out basic and applied researches, synthesized two series of heteropoly compounds having Keggin and Dawson structure, and studied their redox property and acidic catalytic property, etc. Our research results captured considerable attention at home and abroad.
