In this study, we successfully synthesize palladium-decorated indium trioxide (Pd/In2 O3 ) hybrid nanoclusters (NCs) using an advanced dual-target cluster beam deposition (CBD) method, a significant stride in developing high-performance ethanol sensors. The prepared Pd/In2 O3 hybrid NCs exhibit exceptional sensitivity, stability, and selectivity to low concentrations of ethanol vapor, with a maximum response value of 101.2 at an optimal operating temperature of 260 °C for 6 at% Pd loading. The dynamic response of the Pd/In2 O3 -based sensor shows an increase in response with increasing ethanol vapor concentrations within the range of 50 to 1000 ppm...
