摘 要：With natural polyphenol compound tannic acid(TA)as the ingredient,copper tannate(CuTA)nanolayer material was formed by self-assembly under the conditions of heating and copper *** ion and tannic acid could coordinate to form Cu-O-C structure which was similar to the Fe-N-C structure of natural heme *** addition,the obtained CuTA nanomaterial possessed excellent peroxidase-like catalytic activity and *** on this excellent enzymatic activity,CuTA nanomaterials could be used for colorimetric detection of hydrogen peroxide with a smartphone and decomposition of organic *** on the structural characteristics and catalytic activity,the copper tannate nanozymes could also serve as potential antibacterial reagents to effectively inhibit the growth of gram-negative and positive bacteria in a low hydrogen peroxide *** work may promote the exploration of novel peroxidase mimetics and broaden the applications of nanozymes.
