Abstract: As environment-friendly catalyst，heteropoly compounds own the merits of non-corrosion，strong acidity，strong oxidization，adjustable acidity and pseudo-liquid property，which were extensively used in the fields of photoelectricity，catalysis，refining technology，chemical engineering and the synthesis of fine chemicals. In this article，the immobilizations and applications of heteropoly compounds in recent years were summarized in detail，and ship-in-the-bottle method，grafting method，channel-coating method and interlayer-embedding method were focused. The heteropoly compound catalysts prepared with these special immobilizations have strong host-guest interaction and/or channel confined effect，which were used in different types of catalytic reactions. With the ship-in-the-bottle method and channel-coating method，both the acidity and oxidation of heteropoly compounds can be kept，while the leaching content of active species is reduced. These advantages make them as the ideal methods for the preparation of immobilized heteropoly compound catalysts，and provide references for high stability catalyst.
