This work studies the use of Cu/Co-MOFs for the removal of doxycycline hydrochloride (DOC) in wastewater. Cu/Co-MOFs were prepared using a solvothermal method and characterized by XRD, SEM, and TG. According to the experimental results, the maximum DOC adsorption capacity of Cu/Co-MOFs within 5 h was 268.5 mg/g. The pseudo-second-order (PSO) kinetic model shows that the R 2 are all greater than 0.99, which proves that the theory DOC adsorption by Cu/Co-MOFs is consistent with practice. According to the Freundlich isotherm model, the adsorption of DOC by Cu/Co-MOFs is a multilayer adsorption. Thus, the results show that Cu/Co-MOFs have practical application value in removing DOC.

Bimetallic Cu@Co-MOFs Mimic Peroxidase for Colorimetric Detection of Glutathione

Yaohua Gu,Jiping Han,Ni Zhang,Weisong Yan,Yue Guo,Huiyi Tan,Changyi Yang,Fuke Wang,Huiqin Yao

Nanozyme possess the advantages of high enzyme simulation activity, low cost, and excellent stability. As a substitute for natural enzymes, nanozyme have demonstrated significant potential in various fields. In this study, a bimetallic organometallic framework Cu@Co-MOFs was synthesized via the hydrothermal method using terephthalic acid (H2BDC) as a ligand and characterized. Cu@Co-MOFs exhibits outstanding peroxidase activity (POD) by catalyzing the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) and other color-developing substrates through •OH formation. A simple, rapid, and reliable colorimetric method for quantitatively detecting glutathione (GSH) was developed based on the Pod-like activity of Cu@Co-MOFs. The linear range of this method was 1–1200 μM with a detection limit of 0.72 μM. This work not only proposes a bimetallic organic framework with high POD as a straightforward and practical platform for visually detecting GSH but also provides a strategy to enhance the performance of nanomaterials.
