Monolayer Co 3 O 4 inverse opal thin film sensors containing periodic arrays of pores have been synthesized by using sacrificial templates. The Co 3 O 4 sensor showed high response to ethanol at 200 o C, as well as high selectivity to xylene and toluene at 250 and 275 o C, respectively. Unprecedentedly, high ethanol response and temperature‐modulated control of gas selectivity were attributed to the highly chemiresistive inverse opal nanoarchitectures and to the tuned catalytic promotion of different gas‐sensing reactions.
