Iron Carbide Features
Iron carbide has excellent performance in terms of rate and electrochemical stability. It is considered to be the next-generation of anode material for lithium-ion batteries. It is also characterized by high hardness and stability. This allows lithium-ion batteries be used in extreme conditions.
Transition Metal Carbide Nanostructures Attract Attention
The nanostructures of the transition metal carbides have received much attention in recent years. This is especially true for iron carbide nanomaterials due to their excellent stability, high catalytic efficiency, and good biocompatibility. Features: Has important application potential for nanomagnetism and Tropsch catalysis (Tropsch), electrochemical energy conversion and storage, and biomedicine. The current preparation methods like solid-phase reaction methods, sonochemical techniques, and the sol-gel method are prone to product agglomeration, as well as difficulty in controlling phase.
Iron Carbide Catalyst: Application
Zhao Yujun’s Tianjin team has been making breakthroughs by using Fe5C2 catalysts in the DMO system to produce alcohol. Researchers first developed an unique hydrogen-methanol vapor mixture gas carbonization process and obtained a relatively durable iron carbide catalyst, mainly composed by Fe5C2 within a reaction atmospheric.
Further studies found that the DMO hydrogenation reaction route using Fe5C2 was different from that of copper-based catalysts, in part because Fe5C2 could selectively activate -OH on the intermediate product methylglycolate (MG), which is why after adding Hydrogen the reaction produced methyl acetate instead of ethyleneglycol on copper-based cats. MA can be further hydrogenated on Fe5C2 with high selectivity to produce alcohol. Fe5C2 did not have significant CC bond-breaking activity. The higher reaction temperature (260 degrees Celsius) resulted in a 90% yield of ethanol, while the by-products were mainly MA. Fe5C2 catalysts are clearly superior to copper-based catalysts in terms of performance.
