Surface engineering of ultrasmall supported Pd x Bi nanoalloys with enhanced electrocatalytic activity for selective alcohol oxidation

Ultrasmall and homogeneous bimetallic Pd x Bi nanoalloys are well distributed on a Vulcan carbon support by a facile, low-cost synthetic strategy. The electrochemical activity of the as-prepared homogeneous Pd x Bi nanoalloy/carbon black nanocomposites is closely related to the content of Bi, revealing their excellent electrocatalytic performance for selective oxidation of monohydric alcohols and vicinal diols in alkali medium.
