Controlled Growth of BaMoO4 Dendrites in Functional Ionic Liquid

摘要

@@1.Introduction Recently, ionic liquids, as benign solvent, have received much attention for organic chemical reactions, catalysis, separations, and inorganic materials synthesis. Especially, ionic liquid have many advantages in the synthesis of inorganic materials[1]. Nanomaterials, such as metal [2], alloy [3], oxide [4], and sulfide [5], etc., have been synthesized in ionic liquids. However, few reports have been reported on the synthesis of metallic salt, though Zhu and co-workers have synthesized PbCrO4 and PbCrO5 nanorods in ionic liquid under microwave irradiation. 6 BaMoO4 with a scheelite structure is an important material in electrooptics due to its production of green luminescence and in electro-optical applications including solid-state lasers and optical fibers. Microwave-assistant heating method may be in favor of the synthesis of hierarchical superstructures, which can provide a very fast heating rate that can promote the nucleation rate in the nucleation period. Ionic liquids are good media for absorbing microwaves, due to they own large organic cation and little inorganic anion, I.e. High polarizability. Another important property of ionic liquids is that different ionic liquids can be designed by introducing some special functional groups into the organic positive ions or the inorganic negative ions of ionic liquid [6].
