Features of Iron Carbide

Iron carbide, a kind of transition metal carbide, has high conductivity, electrochemical stability and excellent rate performance, and is regarded as the next generation of lithium-ion battery anode materials. In addition, it also has the characteristics of high hardness and thermal stability, allowing lithium-ion batteries to be used under extreme harsh conditions.

Transition Metal Carbide Nanostructures Attract Attention

In recent years, the nanostructures of transition metal carbides have attracted wide attention from researchers, especially iron carbide nanomaterials, due to their high saturation magnetization, excellent stability, high efficiency catalytic activity, and good biocompatibility. Features, has important application potential in the fields of nanomagnetism, Tropsch synthesis (Tropsch) catalysis, electrochemical energy storage and conversion, and biomedicine. However, currently commonly used preparation methods such as solid-phase reaction, sonochemical methods, and sol-gel methods, often have agglomeration of products and difficulty in phase control.


Application of Iron Carbide as Catalyst

In recent years, Zhao Yujun's team from Tianjin University has innovatively used Fe5C2 catalysts in the DMO hydrogenation system to produce ethanol and made breakthrough progress. The researchers first developed a unique hydrogen and methanol vapor mixed gas carbonization process, and obtained a relatively stable iron carbide catalyst mainly composed of Fe5C2 in a reaction atmosphere.

Further studies have found that the DMO hydrogenation reaction route on Fe5C2 catalyst is different from the traditional copper-based catalyst, mainly because Fe5C2 can selectively activate the -OH of the intermediate hydrogenation product methyl glycolate (MG), so that after adding Hydrogen reaction produces methyl acetate (MA) instead of ethylene glycol (EG) on copper-based catalysts. MA can be further hydrogenated on Fe5C2 to produce ethanol with high selectivity. In addition, the Fe5C2 catalyst did not exhibit significant C-C bond breaking activity. Therefore, at a higher reaction temperature (260 °C), a 90% ethanol yield was obtained, and the by-product was mainly MA. Obviously, Fe5C2 catalysts show unique performance advantages over copper-based catalysts.
