Hydrogenated Fe doped amorphous carbon is synthesized via mechanically alloying. XANES analysis suggests that Fe is considered to bond with either C or H atom where the first principle calculations reveals that two types of H-C bonding is confirmed. Weak H-C bond is observed near Fe atom while strong H-C bond is seen far from Fe atom. Electronic structure discovered that weak H-C bonding is induced by Fe atoms where Fe form ionic like bond with surrounding C, resulting in the weak H-C interaction. Thus, two different types of H-C bonding is confirmed within Fe doped amorphous carbon.

揭示铁掺杂无定形碳中的多氢键状态

氢化的铁掺杂非晶碳是通过机械合金化合成的。XANES分析表明，Fe被认为与C或H原子键合，其中第一原理计算表明已确认两种类型的HC键合。在Fe原子附近观察到弱HC键，而在Fe原子附近观察到强HC键。电子结构发现，HC弱键是由Fe原子诱导的，其中Fe与周围的C形成离子样键，导致HC弱相互作用。因此，在掺铁的无定形碳中证实了两种不同类型的HC键合。
