The efficient detection and capturing of CO2 is an important strategy in slowing down global warming. Now, writing in Advanced Materials, Jennifer Rupp and colleagues report a simple, fast and stable potentiometric electrochemical lithium garnet-based CO2 sensor. This device can selectively detect a wide range of CO2 concentrations at substantially lower operating temperatures than state-of-the-art sensors.

Such sensors also lack long-term chemical stability in humid environments and can exhibit cross-reactivity with other gases. “A CO2 sensor should have fast reaction kinetics, be small in device form factor and operate at low temperatures to ensure efficient CO2 tracking in households and commercial areas,” says Rupp.
