The detection of carbon dioxide, a highly oxidized and largely inert gas, has proven difficult within mixtures of multiple gases owing to the presence of competing gas such as oxygen, carbon monoxide and water vapor ? all of which are far more chemically active. It stands to reason, therefore, that the clear benefits of having robust and inexpensive devices to provide a quantitative analysis of CO2 concentrations in admixture with other gases provides more than enough impetus for the continued development of such devices. Much of the present sensing technology depends largely upon spectroscopic methods which become unreliable when the mixture of gases contains spectroscopically similar resonances. Alternative methods, such as semiconducting field effect transistors, and semiconductive oxide sensors operate constantly at temperatures in excess of 200 °C (upwards of 800 °C) making them both power hungry and potential ignition sources in areas with flammable or explosive gases. Here, we present the possibility for MOFs to act as platforms for sensing analytes at relatively low temperatures.
