Despite the interest in proton exchange membrane (PEM) technologies (fuel cells and electrolyzers) for energy applications, low stability of electrolyte materials under working conditions (i.e., humidity temperature) is one their major limitations. Metal–organic frameworks (MOFs) have recently emerged as promising electrolytes due to higher compared with currently applied organic polymers, conductivity, outstanding porosity.

The development of probes with sensitive and prompt detection volatile organic compounds (VOCs) is great importance for protecting human health public security. Herein, we successfully prepared a series bimetallic lanthanide metal-organic framework (Eu/Zr-UiO-66) by incorporating Eu3+ fluorescence sensing VOCs (especially styrene cyclohexanone) using one-pot method. Based on the multiple signal responses Eu/Zr-UiO-66 toward cyclohexanone, ratiometric probe (I617/I320) (I617/I330) as output signals was developed to recognize respectively. Benefitting from response, limits (LODs) (1:9) cyclohexanone were 1.5 2.5 ppm, These are among lowest reported levels MOF-based sensors, this first known material cyclohexanone. Fluorescence quenching mainly owing large electronegativity resonance energy transfer (FRET). However, FRET accounted Moreover, exhibited good anti-interference ability recycling performance More importantly, visual recognition EB vapor can be directly realized naked eyes test strips. This strategy provides sensitive, selective, reliable method
