Zr6O4(OH)4 Based Metal-Organic Frameworks for the Enhanced Chemiresistive Sensing of Ethanol

A novel nanoparticles spilled-over In2O3 microcubes-enabled sustainable chemiresistor for environmental carbon dioxide monitoring

“…Selectivity is one of the most important parameters for the fabrication of gas sensors; it gives an idea about how selective the sensors are regarding the detection of a particular gas for which it is fabricated with the rejection of the other gases present at the same time [30]. The selectivity test of the In 2 O 3 sensors was performed for different gases, including methanol, ethanol, acetone and ammonia, at 200 ppm concentration at RT.…”

“…For instance, Zr 6 O 4 (OH) 4 -based MOFs have been utilized for ethanol gas sensing, achieving a limit of detection of 8.69 ppm, while Fe-MOFs have demonstrated selective detection of acetone ranging from 1.68 to 10 ppm, and a response time of 64 s, followed by a recovery time of 166 s at 50 °C. 27,28 Additionally, bimetallic Zn-based MOFs have exhibited the lowest response time of 9 s at 50 ppm of formaldehyde, while phthalocyanine-based MOFs have shown a response time of 36 s with a detection limit of 10 ppm for methanol sensing. 29,30 Unfortunately, MOFs have some limitations, such as lower conductivity, which hinders their sensing performance.…”
