Porous CeB6 nanostructure: a step towards rapid adsorption of methylene blue

Porous CeB6 nanostructure: a step towards rapid adsorption of methylene blue Porous CeB6 nanostructure was successfully synthesized at 700 °C for 2 h under argon atmosphere by a melt-assisted method using CeCl3 and NaBH4 as reactants, NaCl-KCl as reaction melt. The obtained product was characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Brunauer-Emmett-Teller (BET) method. XRD pattern and Raman spectrum confirmed the formation of CeB6 with high purity. SEM and TEM results showed CeB6 powder had a mesopore structure and consisted of nanoparticles with mean size of ~ 8 nm. Porous CeB6 had high surface area of 64.14 m2 g−1 and pore volume was 0.132 cm3 g−1. Adsorption property of porous CeB6 for methylene blue was also evaluated. The results displayed that adsorption efficiency of 80% on porous CeB6 can be realized rapidly within 10 min with adsorption capacity of 6.75 mg/g. Repeatability test showed that porous CeB6 had the potential to be a reusable adsorbent for MB rapid removal. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of the Australian Ceramic Society Springer Journals

Abstract

Porous CeB6 nanostructure was successfully synthesized at 700 °C for 2 h under argon atmosphere by a melt-assisted method using CeCl3 and NaBH4 as reactants, NaCl-KCl as reaction melt. The obtained product was characterized by X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Brunauer-Emmett-Teller (BET) method. XRD pattern and Raman spectrum confirmed the formation of CeB6 with high purity. SEM and TEM results showed CeB6 powder had a mesopore structure and consisted of nanoparticles with mean size of ~ 8 nm. Porous CeB6 had high surface area of 64.14 m2 g−1 and pore volume was 0.132 cm3 g−1. Adsorption property of porous CeB6 for methylene blue was also evaluated. The results displayed that adsorption efficiency of 80% on porous CeB6 can be realized rapidly within 10 min with adsorption capacity of 6.75 mg/g. Repeatability test showed that porous CeB6 had the potential to be a reusable adsorbent for MB rapid removal.
