Magnetic metal-organic frameworks (MOFs) are promising precursors for generating diverse carbon-based nanostructures due to their facile recovery and separation, as well robust mechanical thermal properties. In this study, a novel Cu-Co bimetallic nanoparticle supported on magnetic MOF derived N-doped carbon was successfully synthesized. The copper ions preloaded within the pores of Co provide abundant exposed Cu active sites. pyrolysis treatment results in hierarchical porous structure with high surface area, contributing mass transfer enhancing reactant diffusion developed catalyst characterized extensively using FT-IR, XRD, BET, BJH, EDX, TGA, VSM, FE-SEM, ICP, XPS techniques. exhibited exceptional catalytic activity C-N coupling one-pot multicomponent reactions. This superior performance can be attributed synergistic effect between nanoparticles incorporated composite, highly structure. demonstrated remarkable stability, maintaining its without significant degradation after five consecutive reaction cycles. innovative approach, capitalizing reinforcing interplay structural compositional advantages, opens up opportunities rational design synthesis efficient catalysts MOF-derived carbon.

Developing sensitive and highly active nanozymes for antioxidant analysis is of the utmost significance in medical diagnosis health monitoring due to their essential roles as free reactive oxygen species scavengers. Here, six metal-organic frameworks (MOFs)-based are developed a dual-mode absorbance/image colorimetric sensor array simultaneous discrimination determination various antioxidants with comparable structural or chemical properties. The catalysts exhibit wide range potent oxidase-like catalytic activities, verified by kinetic parameters, presence dispersed transition metallic bimetallic redox nodes. These efficiently catalyze oxidation colorless 3,3',5,5'-tetramethylbenzidine (TMB) blue TMBox, resulting noticeable absorption RGB color changes at 650 nm. Various demonstrate different reducing capabilities leading generation fingerprint-like spectral patterns. pattern recognition chemometrics methods including principal component (PCA) linear discriminant (LDA) represent well-separated clustering ascorbic acid, dopamine, uric cysteine, glutathione, thiocyanate, tannic gallic acid. assay provides detection (0.1-75 μM) limits low 30 nM. successfully discriminated concentrations, mixtures, interferences. Furthermore, sensor's applicability biologically relevant was validated urine plasma samples. Overall, MOF-based nanozyme offers promising platform discriminating determining potential applications.
