Thus, the catalytic conversion of greenhouse gases such as methane into liquid fuels facilitated by the input of electrical energy presents an immense opportunity for new energy sources. This work presents a series of catalysts based on Pd-doped with Cu supported on TiO2 to evaluate the electrocatalytic activity in a fuel cell reactor for the conversion of methane to methanol and energy co-generation. The nanostructures of the catalytic materials were analyzed by TEM and by XRD. To monitor the oxidation products obtained from the methane oxidation, such as methanol and formate were employed the FTIR and Raman spectroscopy was used to qualify the methanol formation, and the HPLC was used to quantify this product. Thus, the use of TiO2 support shows promising results for the conversion of methane to methanol. In addition, the presence of Pd favors the formation of alcohol in addition to increasing the electrical power of FC. |
