Sheet-on-sheet architectural assembly of MOF/graphene for high-stability NO sensing at room temperature

Abstract

Fractional exhaled nitric oxide (FeNO) is a biomarker describing the inflammatory processes in the respiratory tract. Directly detecting ppb-level Nitric Oxide (NO) with chemiresistive sensors at room temperature is...

Advancing Metal–Organic Framework Designs for Room-Temperature Chemiresistive Gas Sensors

“…Additionally, 2D conductive MOFs are often characterized by lower chemical stability and limited recyclability, resulting from the strong gas interactions that hinder the dissociation of gas molecules from the active sites. − To overcome these limitations, two general methodologies for designing MOF-based composites as room temperature chemiresistors have been established. The first involves enhancing the performance of 2D conductive MOFs by combining them with other materials, such as polymers, graphene, metal nanoparticles (M-NPs), − metal sulfides, and metal oxides . The second strategy utilizes the unique porosity of 3D nonconductive MOFs to improve the adsorption of target molecules or to offer a sieving effect for gas mixtures .…”
