Herein, ultra-small NiFeO hollow particles, with the diameter and wall thickness of only 6 and 1.8 nm, respectively, were anchored on a graphene surface based on the nanoscale Kirkendall effect. The hybrid exhibits an excellent electromagnetic wave absorption property, comparable or superior to that of most reported absorbers. Our strategy may open a way to grow ultra-small hollow particles on graphene for applications in many fields such as eletromagnetic wave absorption and energy storage and conversion.
在此，基于纳米级 Kirkendall 效应，将直径和壁厚分别仅为 6nm 和 1.8nm 的超小 NiFeO 空心颗粒锚定在石墨烯表面上。该复合材料表现出优异的电磁波吸收性能，可与大多数报道的吸收剂相媲美或更优。我们的策略可能为在石墨烯上生长超小空心颗粒开辟一条道路，从而应用于电磁波吸收、储能和转换等多个领域。
