Title: Electrosynthesis of thin sol-gel films at a three-phase junction
Abstract: Thin, functionalised silica films of between 4 and 15 nm thickness were by sol-gel processing at an electrode organic phase aqueous junction by slow withdrawal of a conducting support through the interface. Protons were electrogenerated in the aqueous and catalysed the hydrolysis of the sol-gel precursor in the phase. The film was characterised using atomic force microscopy, electron microscopy, ellipsometry, infrared spectroscopy, and scanning electrochemical microscopy. The thickness, on gold, was determined to be less than 10 nm and the of imidazolium functional groups was estimated to be 1.2 nm(-2). The film obtained on ITO is approximately twice compared to the gold support. (C) 2011 Elsevier Ltd. All rights reserved.
