中文摘要	polyoxometalates (h3pw12o40, h4siw12o40 and h3pmo12o40) have been proven to possess intrinsic peroxidase-like activity for the first time, which can catalyze oxidation of the peroxidase substrate 3,3',5,5'-tetramethylbenzidine (tmb) by h2o2 to form a blue color in aqueous solution. among them, h3pw12o40 (pw12) exhibits higher catalytic activity to tmb than natural enzyme hrp and other two poms. in addition, h3pw12o40/graphene exhibited higher activity than h3pw12o40 in this catalytic oxidation reaction due to the effect of graphene in promoting the electron transfer between the substrate and catalyst. poms/h2o2/tmb system provides a simple, accurate approach to colorimetric detection for h2o2 or glucose. the colorimetric method based on poms showed good response toward h2o2 and glucose detection with a linear range from 1.34 x 10(-7) to 6.7 x 10(-5) mol/l and 1 x 10(-7) to 1 x 10(-4) mol/l, respectively. the results showed that it is a simple, cheap, more convenient, highly selective, sensitive, and easy handling colorimetric assay.
