                         structural/morphological characterization of Sb2O3 nanostructures 
                         modified by Pd nanoparticles and its use as a Fuel Cells 
                         electrocatalyst and as non-enzymatic amperometric sensor for 
                         ethanol. Interesting Sb2O3 surface modifications due to Pd 
                         nanoparticles were observed, such as the loss of spherical shape 
                         and the appearance of superficial pores. As an electrocatalyst 
                         Pd/Sb2O3 exhibited two times higher catalytic activity at a 
                         constant potential than carbon-supported Pd nanoparticles to 
                         oxidize ethanol in alkaline media (current densities of 348 
                         \μA cm\−2 and 165 \μA cm\−2 at 
                         \−0.3 V vs. Ag/AgCl 3.0 M, respectively). To the extent of 
                         our knowledge this result is the first one describing such an 
                         enhancement of the Pd activity only by means of alteration of the 
                         support. Moreover, as an amperometric sensor for ethanol, the 
                         electrode showed a linear response in a broad range of 
                         concentrations with a detection limit of 0.10 \μM and 
                         sensitivity between of 1.47 to 1.00 \μA mM\−1 
                         cm\−2 . The combined findings presented in this work 
                         revealed Pd/ Sb2O3 can be a promising material for Direct Ethanol
