TL;DR: In this paper, the electrochemical oxidation of ethanol on platinum, rhodium, and platinum−rhodium electrodes was studied using on-line differential electrochemical mass spectrometry (DEMS) and in-situ infrared sp...

TL;DR: It was found that the partitioning of the methanol precursor among the end products on supported platinum nanoparticles is strongly dependent on particle size distribution, and it is postulated that the coupling among particles of different sizes via soluble products must be considered in order to understand the particle size effects on the observed trends of product formation.

TL;DR: In this article, the influence of the composition of Pt-Rh/C catalysts on the CO2 yields was investigated and it was concluded that electronic effects played a key role in the mechanism of ethanol oxidation.

TL;DR: In this article, the authors investigated the ethanol-platinum interface in acidic aqueous solution using infrared-visible sum frequency generation (SFG) spectroscopy and theoretical calculations of vibrational spectra in order to identify the intermediates present during the electro-oxidation of ethanol.

TL;DR: In this paper, the authors used differential electrochemical mass spectrometry (DEMS) and UV-Vis spectroscopy to detect ammonia in NaOH solution at polyrrole or N-methyl polypyrrole film sensors polarized at 0.35 V (Ag/AgCl).
