A paper entitled "A straightforward implementation of in situ solution electrochemical 13C NMR spectroscopyfor studying reactions on commercial electrocatalysts: ethanol oxidation" by Long Huang, Eric G. Sorte, Shi-Gang Sun and YuYe J. Tong has been published on the Chem. Commun.website as an accepted manuscript on April 02, 2015 (DOI: 10.1039/C5CC00862J). The paper reports the first in situ solution electrochemical 13C NMR study of ethanol oxidation on Pt and PtRu electrocatalysts. We discovered that (1) the complete oxidation of ethanol to CO2 only took place dominantly at the very beginning of a potentiostatic chronoamperometric (CA) measurement and (2) the PtRu had a much higher activity in catalysing oxygen insertion reaction that leads to acetic acid.
