Ionic liquids as a green medium, having a low vapor pressure, non-flammable, and low surface tension, high thermal stability, the ability to dissolve, and wide range of fluid process, etc.. Alternative to traditional volatile organic solvents for organic synthesis, and the extraction and separation, the field of catalysis, micro and nano materials synthesis. In recent years, there have been many reported a regulation of the use of ionic liquid synthesis of one-dimensional nanomaterials, three-dimensional petals nanoparticles, HollowNanosphere on. About ionic liquids gathered in the water system, and similar traditional surfactants in aqueous systems form micelles proved to us that the ionic liquid can play a role similar to the common surfactant in the preparation of the material. But about regulation of ionic liquids the synthetic Cu 2 O micro / nano-crystalline reported rarely. In this paper, the liquid-phase reduction synthesis in ionic liquid supporting role the morphology controlled Cu 2 O micro / nano-crystalline. The method is easy to operate, the system is not easy to introduce impurities in the closed state. Analysis of ionic liquids in the regulation of the synthesis of the impact of factors has been the role model, so as to provide a theoretical basis for design and further application of ionic liquid molecules. As part of the National Natural Science Foundation of China (No.20873036), the main contents are as follows: (1) imidazole-based ionic liquid preparation and purification. Was prepared according to the synthetic methods reported in the literature, the [C 8 mim] X-(X = Cl , - Br - , PF 6 - ), [C n mim] [BF 4 ] (n = 4, 6, 8), [ MIMCH 2 COOR] Cl (R =-CH 3 ,-CH 2 CH 3 ,-CH 2 CH 2 CH 3 , - (CH 2 ) 2CH 3 ) ten kinds of ion liquid, and its purification and detection. (2) Solvothermal glycol as a reducing agent in [C 8 mim] [the BF 4 ] ionic liquid supporting role successfully synthesized dispersion The petals of a controlled morphology Cu 2 O micro / nano crystal. The effects of reaction temperature, reaction time, reactant concentration as well as the amount of ionic liquid crystal synthetic Cu 2 O, has been synthesized Cu 2 O micro / nano petals crystal optimal conditions. And to carry out the activity of Cu 2 O crystals decolorization of methylene blue solution adsorption and photodegradation. (3) in the ionic liquid [C 8 mim] X (X = Cl - Br-, PF6-) [C n mim ] [BF 4 ] (n = 4, 6, 8), [MIMCH 2 COOR] Cl (R =-CH 3 , - CH 2 CH 3 ,-CH 2 CH 2 CH 3 , - ( CH 2 ) 2CH 3 ) supporting role, ethylene glycol as the reducing agent, Solvothermal Cu 2 O micro / nano the crystal investigated ionic liquid cations alkyl chain length and anion type studied morphology and size of the product obtained. And on this basis, the mechanism of regulation of ionic liquid synthesis Cu 2 O crystals. (4) the use of low-temperature liquid phase method, with glucose as the reducing agent, the supporting role of the [C 8 mim] [BF 4 ] successfully prepared a small particle size and evenly dispersed Cu 2 O micro / nano-cauliflower-like structure. Studied the influence of the anion of the ionic liquid conformation and cationic alkyl carbon chain length of the product crystallized.
