摘要

在10和26.6 kPa的压力下，通过同时蒸发凹形碳板上的铁和钛丝，优先制备了直径小于10 nm并覆盖石墨层的FeTi团簇。为了将这一结果与惰性气体气氛中团簇形成的结果进行比较，还讨论了氩气压力为10kpa时的结果。无序FeNi团簇的形成主要发生在H2气体环境中。

Growth of Functional FeTi Clusters Covered with Carbon Layer

FeTi clusters with a diameter of less than 10 nm and covered with a graphitic layer have been preferentially produced in an H2 gas atmosphere at pressures of 10 and 26.6 kPa by the simultaneous evaporation of Fe and Ti wires from a concave carbon boat. To compare this result with cluster formation in an inert gas atmosphere, the result for an Ar gas pressure of 10 kPa is also discussed. The formation of disordered FeNi clusters predominately took place in an H2 gas atmosphere.
