Abstract

The activation of methane (CH4) gas to produce more valuable liquid hydrocarbons has long been a challenging issue in catalytic research. Electrochemical oxidation is one of the main methods of methane activation and can usually proceed at in ambient temperature. However, the lack of efficient electrocatalysts limits the practical application of this strategy. In this study, ZrO2 nanotube powder with a high specific surface area was decorated with Co3O4 nanoparticles and used as the electrochemical anode for the partial oxidation of methane to generate C3 alcohol products. The Co3O4 nanoparticles formed on outer the surface of the ZrO2 nanotubes offer an accessible diffusion route for methane gas, resulting in a low onset potential for electrochemical methane activation. A high production rate of approximately 2416 μmol gcat−1 h−1 was obtained at 1.6 V (vs RHE) after 12 h of reaction. This nanostructure engineering strategy contributes to the enhancement of catalytic activity for electrochemical methane oxidation with the production of higher alcohols, which could provide a new catalyst synthesis strategy for researchers.
