Metal–organic framework based systems for CO₂ sensing

Abstract

Monitoring CO2 levels in the atmosphere as well as in work place environments is strictly regulated. Curent commercial solid-state polymeric sensors have low operating temperature, yet exhibit low selectivity. Molecular...

Recent Progress in Metal-Organic Framework Based Fluorescent Sensors for Hazardous Materials Detection

“…CO 2 , as a major greenhouse gas, not only causes global warming and ocean acidification, but also causes symptoms when present above safe CO 2 levels, such as headache, energy loss, fatigue, inquietude, jelly legs, and pulmonary ventilation problems [ 24 , 25 ]. Molecular systems such as LMOFs are reliable materials that can be applied to CO 2 sensing [ 26 ]. They are made by powerful interactions between metal ions or clusters with easy-to-modify organic linkers and additionally exist with a high surface area and well-defined accessible pores.…”

Metal–organic framework-based photonic crystal platforms for gas sensing: a review

“…Nature, the environment which human beings live by, has always been damaged a lot. Formaldehyde, ammonia (NH 3 ), hydrogen sulfide (H 2 S), nitrogen oxides (NO x ), sulfur oxides (SO x ), carbon oxides (CO x ) and others volatile organic chemicals (VOCs) vapors from industrial processes and buildings materials cause the major threat to human and the environment [8][9][10][11][12][13][14][15][16] . This raises the need for a system of environmental monitoring such as the internet of things (IOT) of environmental protection.…”

“…Formaldehyde, ammonia (NH 3 ), hydrogen sulfide (H 2 S), nitrogen oxide (NO x ), sulfur oxide (SO x ), carbon oxide (CO x ) and other volatile organic chemical (VOC) vapors from industrial processes and building materials pose a major threat to humans and the environment. [8][9][10][11][12][13][14][15][16] This increases the need for environmental monitoring systems such as the internet of things (IOT) for environmental protection. Gas sensors, as essential sensors for environmental monitoring, will help build environmental IOT.…”

Chemical sensors based on ionically conductive metal–organic frameworks for selective cadaverine detection

“…[30][31][32][33][34][35][36] In the past few years, chemical sensors based on electronically conducting MOFs (EC-MOFs) have been reported. [37][38][39][40][41][42][43] These sensors can measure samples in realtime and do not require sample pretreatment or separation. They can be fabricated at a low cost and integrated into electronic circuits with a fast response speed.…”
