Metal-Organic Framework Based Electrochemical Sensors

Abstract

It is well-known that thin sheet MOFs are of interests in the application of sensors because the bulk crystalline nature of MOFs represent poor electron transfer efficiency and strong diffusion resistance, limiting their electrocatalytic performances. Moreover, applying pure MOFs in the sensing and energy-related fields have shown some major drawbacks such as poor electronic conductivity low accessibility to active metal sites, instability in aqueous environment, low mechanical stability of the electrocatalyst layer. It is believed that combining different MOFs and other functional materials into the same framework is likely to generate not only new defects in the structure of MOFs but also the excellent synergistic effects between different metals, improving their optical, electronic, and magnetic properties. With this regard, this section highlights a new point of view about the integration of the MOF as a part of the sensor.
