Designing efficient nanozyme to construct rapid analytical method for tannic acid (TA) content control has significant influence in food science area. Herein, by one-step self -assembly between Fe3+ and 2, 3, 6, 7, 10, 11hexahydroxytriphenylene (HHTP), an amorphous nanomaterial (Fe-HHTP) was synthesized and fully characterized by TEM, AFM, XRD, EDS element mapping and XPS. Then, its peroxidase-like activity was explored by using H2O2 and 3, 3 ', 5, 5 '- tetramethylbenzidine (TMB) as typical substrates. Due to the inhibition of TA on FeHHTP catalyzed chromogenic reaction, a rapid and accurate c...
