In this work, a novel bifunctional zirconium dioxide @ zeolitic imidazolate framework-90 (ZrO 2 @ZIF-90) nanozyme was successfully developed for the catalytic degradation and electrochemical detection of methyl parathion (MP). The ZrO 2 @ZIF-90 nanozyme with phosphatase hydrolysis activity can convert MP into p-nitrophenol (p-NP). The addition of ZrO 2 riched in Lewis acid Zr(IV) sites significantly enhanced the phosphatase hydrolysis activity of ZIF-90. ZrO 2 @ZIF-90 also displayed satisfactory electrocatalytic performance on account of the high surface area, high porosity and powerful enrichment ability of the ZIF-90 and the excellent ion transfer capacity of ZrO 2 . A ZrO 2 @ZIF-90 nanozyme modified glassy carbon electrode (ZrO 2 @ZIF-90/GCE) was then fabricated to analyze p-NP formed through MP degradation. Under the optimized conditions, the developed sensor displayed satisfactory analytical performance with a low limit of detection of 0.53 μmol L -1 and two wide linear ranges (3-10 μmol L -1 and 10-200 μmol L -1 ). ZrO 2 @ZIF-90 nanozyme accomplished to the degradation and electrochemical detection of MP in river water and spiked fruits. This study identifies a promising new strategy for the design of bifunctional nanozymes for the detection of environmental hazards.

“…Compared with the grafting-from strategy, grafting-to is a powerful strategy with the advantage of covalently bonding the polymer to the MOF without exposing the MOF to harsh polymerization conditions, as evidenced by the successful grafting-to preparation of the covalently bonded ZIF-90-PI. 138 In this case, the grafting-from strategy failed. 62 In 2014, Mirkin's group reported pioneering results of a grafting-to strategy using heterochain polymers, which established covalent linkages between nucleic acids and MOFs via a Cu-free modified alkyne click reaction (Fig.…”

“…This composite showed a high H 2 permeability (487.0 barrer) and improved gas selectivity for H 2 /CO 2 (35.8), which was almost seven-fold higher than that of the physically mixed MOFs and polymers. 138 Liquid separation. The covalently connected MOF-polymer composites could be applied to not only gas separation but also various liquid-separation applications, including water treatment and pollutant separation.…”

“…84 These characteristics of defective MOFs provide a versatile platform for improving MOF–polymer interfacial adhesion and increasing selective sorption properties. The relevant reports have demonstrated that the defective MOFs in MMMs, such as Ui-66, 19,85–88 ZIF-8, 89,90 ZIF-90, 91 and Ni-MOF, 22 show great potential for enhancing gas separation performance.…”
