Ethanol sensing behavior of Pd-nanoparticles decorated ZnO-nanorod based chemiresistive gas sensors

The development of defined hierarchical transition metal oxide nanostructures has attracted remarkable attention due to their superior chemiresistive gas sensing performances. In the present study, vertically aligned zinc oxide nanorods (ZnO-NRs) were grown by chemical vapor deposition (CVD) and precise decoration with palladium nanoparticles (Pd-NPs) on their surfaces, at different deposition times, was done through unique RF magnetic...
