摘　　要：合成了一个系列的铜钨钼硅多元取代多金属含氧簇合物 :K4H2 [Cu( OH2 ) Si Mo11-n Wn O39].x H2 O　 ( n=2 ,5 ,7,9;x=2 1～ 2 3 ) ,通过 IR,UV,XPS,TG- DTA,XRD对其性能进行了表征 ,并以H2 O2 的反应体系 ,考察了合成的簇合物对 H2 O2A series of multicomponent polyoxometalate clusters containing copper were synthesized. The general molecular formula was determined:K 4H 2[Cu(OH 2)SiMo 11- n W n O 39 ]. x H 2O( n=2,5,7,9;x =21~23).By means of IR spectra, UV spectra, XPS spectra and thermoanalysis, the properties, structural characteristics and catalytic behavior of the novel compounds were investigated, and the decomposition of H 2O 2 catalyzed by these compounds was also studied.
