Structural effects in electrocatalysis: oxygen reduction on platinum low index single-crystal surfaces in perchloric acid solutions
TLDR
Oxygen reduction was found to be sensitive to the crystallographic orientation of the platinum electrode surface as discussed by the authors, and a special cleaning procedure has been developed to remove impurities from the surface prior to the oxygen reduction measurements.About:
