Abstract

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 conductivities up to 0.01 S cm⁻¹ under 100% CO₂ and 65% Relative Humidity (RH).
