TY - JOUR T1 - Amphi-functional mesoporous silica nanoparticles for dye separation JF - Journal of Materials Chemistry A Y1 - 2017 A1 - Shinde, Pravin A1 - Sen Gupta, Sayam A1 - Singh, Baljeet A1 - Polshettiwar, Vivek A1 - Prasad, Bhagavatula L. V. AB - Synthesis of amphi-functional mesoporous silica nanoparticles (similar to 80 nm) by stepwise chemical modifications of outer and inner pore surfaces is reported. These materials display a clear "Janus" like character and are able to selectively and completely separate hydrophobic dyes form a mixture of dyes. Our results clearly suggest a clear partition of more hydrophobic dyes into the pores from a mixture of two dyes. In addition this material displays a remarkable recycling ability for 10 cycles with up to similar to 99% dye removal from water. VL - 5 IS - 28 U3 - Foreign U4 - 8.262 ER -
