The papers from the first step of the study inorganic nanomaterials - Preparation and characterization of inorganic nanomaterials begin using solvothermal on the use of amino acids as adjuvants by regulating the types and amount of reactants , solvents , reaction time, reaction temperature experiments parameters were prepared monodisperse nanostructures with different morphologies iron-cobalt layered double hydroxides , iron cobalt and cerium oxide nanomaterials , and were characterized by XRD , FT -IR , SEM , TEM , TGA, UV ??-vis and VSM a variety of techniques to the analysis and characterization of the sample composition , morphology , performance, etc. , the major findings are as follows: as solvent ethylene glycol and deionized water , respectively , to several amino acids , supplemented by additives , by changing the amino acid concentration , hydroxide experimental conditions, such as sodium concentration , reaction temperature and reaction time , Solvothermal successfully prepared spherical flower -like and octahedral morphology of iron cobalt layered double hydroxides Co of Ⅱ 5.84Fe Ⅲ 2.16 ( OH ) 16 (CO3 ) the 1.08 · 0.32H2O (JCPDS 50-0235), the self-assembly of the particle size of 15nm spherical of CoFe2O4 and particle size of 100nm CoFe2O4 (JCPDS 22-1086) microspheres as well as different shapes such as spherical , square and rod different size of the nano- CeO2 (JCPDS 34-0394); through a large number of comparative experiments , and found that the amino acid concentration , hydroxide concentration, reaction time and the reaction temperature is an important factor of the sample topography solvothermal synthesis affect . Testing of the the different morphologies iron cobalt layered double hydroxides samples and cobalt ferrite sample adsorption properties of organic wastewater . The results showed that the samples of anionic dyes have good adsorption properties of the sample morphology has also affected the adsorption performance . In this thesis, using amino acids as nanomaterial synthesis auxiliary agent to achieve the controlled synthesis of different materials , new materials and ways to provide for effective governance anionic organic dye wastewater .
