Necklace-like nanostructures of cadmium hydroxide: Controlled synthesis with bubble-template and its separation property on dye
چکیده انگلیسی

Ultra-long and flexible necklace-like nanostructures of cadmium hydroxide were successfully prepared in the n-octanol/aqueous liquid system through the microwave heating approach, and a novel mechanism based on the synergistic effect of bubble-template and interface-assistance (SEBI) was proposed. The obtained products were carefully characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), field-emission scanning electron microscopy (FESEM), FT-IR spectrum, UV–vis adsorption spectrum and BET measurement. Control experiments revealed that the morphologies of the building blocks and the final products could be readily tuned by the reaction parameters. Further experiments evidenced that the positively charged Cd(OH)2 could effectively adsorb or separate the negatively charged dye molecules, and the hierarchical structure could improve its separation performance.

Ultra-long and flexible necklace-like nanostructures of cadmium hydroxide were successfully prepared in the n-octanol/aqueous liquid system with a novel double-soft-template mechanism of the synergistic effect of bubble-template and interface-template (SEBI). Further experiments proved that the synthesized nanomaterials could improve anionic dye separation performance, compared with conventional nanostructures of cadmium hydroxide.Figure optionsDownload as PowerPoint slide
