Process for preparing porous iron oxide-zirconia composite catalyst, porous iron oxide-zirconia composite catalyst prepared thereby, and method for producing alcohol using the catalyst

Catalyst that converts the greenhouse gas methane into alcohol at room temperature and pressure

This technology relates to a method for producing a porous iron oxide-zirconia composite catalyst, a porous iron oxide-zirconia composite catalyst produced thereby, and a method for producing alcohol using the same under room temperature and pressure conditions.

Existing methane conversion technology had the limitation of high alcohol production costs due to the complex process of high temperature and high pressure. To solve these problems, this technology proposes a porous iron oxide-zirconia composite catalyst and its manufacturing method that directly convert methane into alcohol under room temperature and pressure conditions.

This composite catalyst can efficiently produce methanol, ethanol, propanol, etc. from methane through electrochemical reaction at low cost and enables energy-efficient, eco-friendly alcohol production.

Key Features:

• Using the synergy effect of iron oxide and zirconia
• Iron oxide plays a role in activating the C-H bond of methane, and zirconia supplies the oxygen necessary for oxidation by adsorbing carbonate (CO₃²⁻) ions in the solution
• Electrochemical methane oxidation reaction occurs at room temperature through the combined action of the two elements
• Carbonate ion adsorption using tetragonal phase zirconia Increases catalyst efficiency by maximizing characteristics.
