  A new gold(III)-aminoethyl imidazolium aurate salt as precursor for nanosized Au electrocatalysts

  摘要：

  In this work the novel, robust, air- and moisture-stable gold(III)-aminoethyl imidazolium aurate salt [Cl3AuNH2(CH2)(2)ImMe][AuCl4] (1) has been employed as precursor for the electrosynthesis of gold nanoparticles (AuNPs) onto ITO electrodes in 0.5 mol dm(-3) H2SO4 aqueous solution without the use of additional additives and/or stabilizers. The electrode termed ILNH2-Au-NPs200 prepared at a fixed electrode-position time (t(d)) of 200 s was characterized with AFM, SEM, XRD diffraction as well as cyclic voltammetry (CVs) and compared with an electrode in which the AuNPs have been electrodeposited from KAuCl4 in the presence of Kl as additive at the same t(d) (Au-NPs200). The effect of the t(d) (i.e. 50 s or 500 s; electrodes ILNH2-Au-NPs50 and ILNH2-Au-NPs500, respectively) was also investigated together with the electrocatalytic activity towards methanol oxidation in alkaline medium of all the prepared electrodes. The comparison with Au-NPs obtained with Kl as additive shows that the presence of the amino-functionalized imidazolium moiety although not relevant in relation to the particle size, favours the metal electrodeposition process and plays an important role in the enhancement of the following parameters: (i) surface coverage (S.C.), (ii) electroactive particle coverage phi(p) %, (iii) electroactive surface area sigma(red(exp))/sigma(red(theor)) and (iv) catalytic efficiency.

  Tetrachloroauric acid HAuCl4 reacts with the ionic liquid 1-(2-aminoethyl)-3-methylimidazolium nitrate [NH2(CH2)(2)ImMe]NO3, (2b) or its dicationic ammonium salt [NH3(CH2)(2)ImMe][NO3](2), (3) in methanolic solutions to give the novel gold(III)-aminoethyl imidazolium aurate salt [Cl3AuNH2(CH2)(2)ImMe][AuCl4] (4). The reaction of 4 with [Bu-n(4)]Cl gives [NH2(CH2)(2)ImMe][AuCl4] (2c) whereas with acetone the dicationic, iminium-functionalized, imidazolium aurate salt [Me2C=N(H)(CH2)(2)ImMe][AuCl4](2) (5) has been isolated. The structures in the solid state of 2c, 3, 4, and 5 have been determined by X-ray diffraction. The electrochemical behaviour of 4 has been examined by Cyclic voltammetry in acetonitrile and compared with 2c and KAuCl4. (C) 2010 Elsevier B.V. All rights reserved.
