Title: “Colorimetric Gas Sensor Based on Metal-Organic Frameworks”

BSAC IdentificationBPN913

Abstract: Carbon dioxide (CO2) has been shown to contribute to poor indoor air quality and associated human health consequences, such as shortness of breath, nasal and optic irritation, dizziness, and nausea. Nondispersive infrared (NDIR) sensors can probe low CO2 concentrations ( 400 ppm) but are expensive and difficult to miniaturize. The commercial colorimetric CO2 sensor is passive and low-cost but lacks the chemical functions necessary for sensitivity to low CO2 concentrations. In this work, we aim to address these shortcomings by using metal-organic frameworks (MOFs) as highly-porous, crystalline, chemically-stable sorbents for strong adsorption of CO2.   The colorimetric CO2 gas sensor is a multi-component device whose variable synthetic strategies enable different degrees of colorimetric CO2 uptake. The adsorption process protonates pH indicators incorporated inside pores to generate color change.
