Resumo
The application of solid electrolyte reactors for methane oxidation and energy co-generation is attractive,
especially with the use of catalysts synthesized from noble metals such as palladium. In this work,
we prepared three different compositions of palladium on carbon support to evaluate the composition
that had the greatest potential for energy generation. Catalysts in the proportions of 5, 10 and 20% of
Pd/C were tested for the conversion of greenhouse gases into organic molecules of higher added value
using electrochemical fuel cell solid electrolyte reactors. The focus of this work was the conversion of
methane into methanol, using the fuel cell as a reactor and the commercial Pd/C as electrocatalyst. The
electrocatalysts were tested at the anode, analyzed by infrared (IR) spectroscopy and their activities verified
by experiments with rotating ring disk electrode (RRDE). Higher levels of palladium (Pd/C 20%) favored
obtaining electrical power, and the intermediate composition (Pd/C 10%) showed a greater production of
less oxidized compounds, such as methanol, in addition to generating electricity.
