Compared to natural enzymes, the development of efficient artificial simulated such as those based on bimetallic materials with high catalytic activity and good stability, is an important way until now. Herein, we employed ZnCo2O4 microspheres carriers synthesize Pt-doped composites different amounts using a one-pot method. The morphology structure synthesized were characterized XRD, SEM, BET, FT-IR, XPS, Zeta potential techniques. It was found that Pt0 adhered well surface microspheres, 12.5% Pt doped ratio exhibiting abundant oxygen vacancies, excellent substrate affinity, peroxidase-like activity. Using fluorescent probes electrochemical methods, mechanism has been explored Pt@ZnCo2O4 can accelerate electron transfer between H2O2 3,3',5,5'-tetramethylbenzidine (TMB). Based optimal loading Pt@ZnCo2O4, colorimetric sensor for visual detection L-cysteine (L-Cys) constructed, wide linear range 0.1~50 µM low limit 0.0163 µM. possesses selectivity, reusability, usage which be applied determination L-Cys in health product capsules recovery rates 96.9%~103.7% RSD 1.07%~6.50%. This work broadens application prospects spinel field biological analysis also provides inspiration new enzymes.
