Chemiresitive sensing allows the affordable and facile detection of small molecules such as H2O and CO2. Herein, we report a novel class of earth abundant post transition metal substituted Keggin polyoxometalates (POMs) for chemiresistive sensing applications, with conductivies up to 0.01 S cm-1 under 100% CO2 and 65% Relative Humidity (RH)
