Chemiresitive sensing allows the affordable and facile detection of small molecules such as H 2 O and CO 2 . Herein, we report a novel class of Earth-abundant post transition metal substituted Keggin polyoxometalates (POMs) for chemiresistive sensing applications, with conductivities up to 0.01 S cm -1 under 100% CO 2 and 65% Relative Humidity (RH).
