High-Sensitivity NO₂ Gas Sensor: Exploiting UV-Enhanced Recovery in a Hexadecafluorinated Iron Phthalocyanine-Reduced Graphene Oxide.

ABSTRACT: Monitoring ultralow nitrogen dioxide (NO₂) concentrations is crucial for air quality management and public health. However, the existing NO₂ gas sensors have several defects, like high cost and power consumption, and exhibit poor selectivity. This study addresses these challenges by presenting a novel hexadecafluorinated iron phthalocyanine-reduced graphene oxide (FePcF₁₆-rGO) covalent hybrid sensor for NO₂ detection. This innovative approach, which overcomes the limitations of fabrication cost, energy efficiency, and gas selectivity, is a significant step forward in gas sensor technology. The sensor demonstrates exceptional sensitivity toward ultralow NO₂ concentrations (15.14% response for 100 ppb) with a rapid 60 s UV light-induced
