Metal-Organic Frameworks for Electrocatalytic Sensing of Hydrogen Peroxide.

The electrochemical detection of hydrogen peroxide (H 2 O 2 ) has become more and more important in industrial production, daily life, biological process, green energy chemistry, and other fields (especially for the detection of low concentration of H 2 O 2). Metal organic frameworks (MOFs) are promising candidates to replace the established H 2 O 2 sensors based on precious metals or enzymes. This review summarizes recent advances in MOF-based H 2 O 2 electrochemical sensors, including conductive MOFs, MOFs with chemical modifications, MOFs-composites, and MOF derivatives. Finally, the challenges and prospects for the optimization and design of H 2 O 2 electrochemical sensors with ultra-low detection limit and long-life are presented.
