Title:
The Electrooxidation of Formic Acid on Pd Nanoparticles: an Investigation of Size-Dependent Performance 
Abstract:
Palladium nanoparticles (Pd NPs) were deposited on highly oriented pyrolytic graphite (HOPG) substrates by using a potentiostatic double-pulse technique. The NPs possessed a narrow size distribution and wide dispersion. The particle density was in the order of 109cm-2.The average height of Pd NPs was controlled in a range of 3 to 50 nm by adjusting the duration of growth pulse. The carbon monoxide (CO) stripping at Pd NPs smaller than 14 nm occurred predominantly at a potential above 1.1 V, whic...    »
