dc.descriptionThe investigation reported in this paper aims the recycling of greenhouse gases and their conversion into fuels or useful chemicals. In the present work, a (TiO2/RuO2)/PTFE gas diffusion electrode (GDE) was designed and characterized to be used in the electrochemical conversion of methane into methanol in conditions of simultaneous oxygen evolution. The GDE was obtained by pressing and sintering TiO2(0.7)/RuO2(0.3) powder and PTFE and used for the electrosynthesis of methanol from methane. In the experiments, methane was inserted into the reaction medium by the GDE and electrosynthesis was carried out in 0.1 mol L-1 Na2SO4 supporting electrolyte. Controlled potential experiments showed that methanol concentration increased with applied potential, reaching 220 mg L-1 cm(2), at 2.2 V vs. a calomel reference electrode and current efficiency for methanol formation was 30%. Mass spectrometry data also indicated the formation of formaldehyde and formic acid, the latter at a similar rate as that of methanol.
