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.

N-Nitrosodimethylamine (NDMA) is a widely recognized disinfection by-product that poses significant carcinogenic risks in drinking water. Conventional methods for NDMA removal, such as nanofiltration and reverse osmosis membranes, have limited efficacy due to NDMA’s small molecular weight polar properties. Advanced oxidation processes (AOPs) shown promise, but traditional Fenton often fall short the chemical structure of nitrosamines NDMA. This study proposes novel, cost-effective approach using one-step carbonization method synthesize catalyst from ferric ammonium citrate (FAC). The resulting FAC-600 integrates zero-valent iron carbide with carbon-based functional groups, enhancing catalytic electron transport activities. Our experiments demonstrated FAC-600/persulfate (PS) AOP system achieves over 90% removal across wide concentration range (50 μg L−1 1000 L −1) dosage 0.5 g L−1. Mechanistic insights revealed superoxide hydroxyl radicals dominate degradation, facilitated by presence dissolved oxygen PS. underscores potential FAC-600/PS robust efficient solution promising safer water through practical application.
