Surface engineering of ultrasmall supported PdBi 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. Ultrasmall and homogeneous bimetallic Pd x Bi nanoalloys anchored on Vulcan carbon demonstrate enhanced electrocatalytic activity for selective alcohol oxidation.
