| Abstract |
Due to their specific structure concave nanoparticles (NPs) have various advantages such as size selectivity, easy accessibility, protect inner materials, etc. Preparation of the concave structured materials from cubic structures has been extensively performed. Generally, many of concave structured nanocubes have been synthesized by using ligands through solution process, in which the concave regions are formed on all the equivalent facets. However, interestingly, it is possible to synthesize concave nanocubes with only one concave region on one of equivalent facets in solid-state reaction. We synthesized Fe3O4 nanocubes with silica shell, and applied heat in hydrogen condition. In this process we observed that the concave structured nanocubes with only one concave region was formed. This phenomena could be ascribed to the reaction between iron oxide and the limited amount of silica, which formed iron silicate at the high temperature. Using this method, specific structured iron oxide NPs can be easily synthesized and applied in various fields. |
