A base-stable metal-organic framework for sensitive and non-enzymatic electrochemical detection of hydrogen peroxide

Metal−Organic Frameworks toward Electrochemical Sensors: Challenges and Opportunities

“…Freire and coworkers also demonstrated the encapsulation of a redox‐active polyoxometalate into MIL‐101(Cr), and the resulting composite material was applied for electrochemical sensor toward ascorbic acid (AA) . Another Cr‐based MOF, MIL‐53(Cr), was also reported to show a high electrocatalytic activity for non‐enzymatic detection of H 2 O 2 , and the electrochemical and sensing activity of the Cr‐based MOF is attributed to the redox activity of the Cr‐based nodes . It should be noted that such Cr‐based MOFs constructed from carboxylate‐based linkers are well known to show excellent chemical stability in water .…”

Facile synthesis of a zeolitic imidazolate framework-8 with reduced graphene oxide hybrid material as an efficient electrocatalyst for nonenzymatic H2O2sensing

“…In recent years, hydrogen peroxide (H 2 O 2 ) has attracted considerable attention due to its important applications in food, industrial engineering, agriculture, medicine and health, clinical control and the environment. [1][2][3] Thus, it would be very valuable to develop a simple, fast, reliable and accurate technique to detect H 2 O 2 . Among the various techniques proposed for H 2 O 2 monitoring, electrochemical methods are the most convenient and effective.…”

Metal-Organic Frameworks for the Development of Biosensors: A Current Overview

“…Lopa et al presented an electrochemical biosensor for the quantification of H 2 O 2 based on MIL-53(Cr) [83]. The MOF was prepared following a microwave-assisted solvothermal synthesis mixing CrCl 3 and terephtalic acid (TPA) in water and further treated with NaOH.…”
