Iron Carbide Features
Iron Carbid is an example of a transition metal caride. This type has high conductivity and electrochemical stability. Additionally, the material has high thermal stability and hardness which allow lithium-ion batteries for extreme use.
Transition Metal Carbide Nanostructures Attract Attention
The nanostructures of transitional metal carbides, particularly iron carbide, have received a lot of attention in recent years. These nanostructures are known for their excellent saturation magnetization, stability and catalytic activity. This feature has great potential for use in areas such as nanomagnetism and Tropsch synthes (Tropsch), energy storage and conversion, biomedicine and biomedicine. However, most commonly used preparation methods like solid-phase reactions, sonochemical and solgel have difficulties in controlling the phase of their products.
Iron Carbide is used as catalyst
Zhao Yujun and his team at Tianjin university have made remarkable progress using Fe5C2 catalysts to create ethanol in their DMO hydrogenation process. This was the first time that a novel hydrogen/methanol vapor mixed-gas carbonization process was developed. The team then created an extremely stable iron carbide catalyst, mainly made of Fe5C2 in reaction.
Studies have shown that DMO hydrogenation on Fe5C2 catalyst works differently from traditional copper-based catalysts. Fe5C2 is able to activate the -OH intermediate hydrogenation product, methyl glycolate (MG) so after addition Hydrogen reaction, it produces methyl Acetate (MA), instead of ethylene glycol(EG) on copper based catalysts. Fe5C2 is capable of further hydrogenating MA in order to obtain ethanol with high selectivity. Additionally, Fe5C2 did not show significant C–C bond breaking activity. A higher temperature of reaction (260 degrees C) was required to achieve a 90% yield. Also, the MA by-product was mostly obtained. Fe5C2 has a distinct advantage over other copper-based catalysts.
