FIDELIS, Carlos H.V.; DONATE, Paulo M.  and  ANDRADE, Adalgisa R. de. Electro-oxidation of ethanol in Ti/IrO2. Quím. Nova [online]. 2001, vol.24, n.1, pp.43-46. ISSN 0100-4042.

It has been carried out an investigation of ethanol electro-oxidation on Ti/IrO2 electrodes. The experimental results show a high selectivity towards acetaldehyde formation thus, offering potential advantages in cost and availability of raw material. It has been observed that the electrode is partially blocked by a film formed after the oxidation of the starting material which can be removed by pulse technique between RDO and RDH onset. The mechanism and the selectivity of the product formed is presented.

Keywords : ethanol; electro-oxidation; iridium oxide.
