Development of Ionothermal Synthesis of Titania Nanomaterial for Waste-Water Treatment

Abstract

In this study, ionothermal synthesis process has been used for the preparation of two different types of Titania nanomaterials and that were utilized in the degradation of waste-water like (sulfan blue). The ionic liquid were used as 1-butyl-3-methylimidazolium dimethyl phosphate ([Bmim] DMP) as (TP) and 1-butyl-3-methypyridium dicyanamide ([Bmpm]DCN) as (TCN) respectively for the synthesis of anatase type Titania nanomaterials and confirmed with X-Ray diffraction pattern (XRD). The particle sizes and surface morphology were characterized by field emission scanning electron microsopy (FESEM), transmission electron microscopy (TEM), and Brunauer-Emmett-Teller (BET). The sizes of the particle were found to be approximately 35±5 nm from the microscopic picture analysis. The nitrogen adsorption analysis measured a surface area of 455 and 220 m2 g-1 and pore volume of 0.25 and 0.15 cm3 g-1 for ([Bmim]DMP) and ([Bmpm]DCN) related synthesis TiO2 nanomaterials respectively.The degradation rate of sulfan blue is higher in the presence of TP as compared to TCN owing to the larger surface area.
