Long chain ionic liquid-assisted synthesis of PS/Pd beads and hierarchical porous Pd–SiO₂

Abstract

1-Hexadecyl-3-methylimidazolium chloride (C16mimCl) can be used as “bridges” to prepare PS/C16mimCl/Pd beads, and Pd-loaded hierarchical porous silica was synthesized using dual templates of the PS/C16mimCl/Pd beads and C16mimCl.

Multifunctional amphiphilic ionic liquid pathway to create water-based magnetic fluids and magnetically-driven mesoporous silica

“…12 More recently, we have employed a C 16 mimCl-assisted synthesis method to prepare polymer/Pd microspheres and a bimodal porous Pd-decorated silica. 13 These research results conrmed that C n mimCl possess a specic templating performance in the synthesis of ordered porous structural materials. However, their potential as modifying agent, especially for the formation of stable C n -mimCl-functionalized magnetic Fe 3 O 4 nanoparticles (NPs) or their multifunctional combination for the fabrication of hybrid porous materials is less commonly known.…”

“…Synthesis of C n mimCl (n ¼ 10, 12,14,16) Amphiphilic ionic liquids, 1-alkyl-3-methylimidazolium chloride (abbreviated as C n mimCl, n is the number of carbon atoms in alkyl chains, n ¼ 10, 12, 14, 16, respectively), were prepared according to a route reported in the literatures. 13,22 All chemicals were purchased from Acrös and used as received. As a typical synthesis of C 16 mimCl, an excess of 1-hexadecyl chloride (33.41 g, 0.128 mol) was mixed with 1-methylimidazole (10.26 g, 0.125 mol).…”
