Abstract: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 electrocatalyt… Show more
