Porosity controlled 3D SnO2 spheres via electrostatic spray: Selective acetone sensors

•To control the porosity, the e-spraying and PS beads templating route are combined, resulting in highly porous structure.•Pt functionalized PH-SnO2 spheres exhibited high response (Rair/Rgas = 44.83) toward 5 ppm of acetone.•Pt-PH-SnO2 spheres exhibited exceptional selectivity toward acetone agains...
