Abstract
Poly(ionic liquid) (PIL) coated ordered mesoporous carbons (OMCs) were prepared by in situ polymerization of 3-ethyl-1-vinylimidazolium tetrafluoroborate ([VEIM]BF4) monomer on OMCs matrix. PIL on the surface of OMCs can provide sufficient binding sites to anchor the precursors of metal ion. PIL/OMCs were employed as support material for the deposition and formation of ultra-fine Pt nanoparticles, via the self-assembly between the negative Pt precursor and positively charged functional groups of PIL-functionalized OMCs. The combination of the unique properties of each component endows Pt/PIL/OMCs as a good electrode material. Compared with the Pt/OMCs nanocomposite, the Pt/PIL/OMCs modified electrode displays high electrocatalytic activity towards hydrogen peroxide (H2O2) and gives linear range from 1.0×10−7 to 3.2×10−3M (R=0.999). The Pt/PIL/OMCs responds very rapidly to the changes in the level of H2O2, producing steady-state signals within 4–5s. A high sensitivity of 24.43μAmM−1 and low detection limit of 0.08μM was obtained at Pt/PIL/OMCs modified electrode towards the reduction of H2O2. The improved activity makes Pt/PIL/OMCs nanocomposite promising for being developed as an attractive robust and new electrode material for electrochemical sensors and biosensors design.
