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

In this work the novel, robust, air- and moisture-stable gold(III)-aminoethyl imidazolium aurate salt [Cl3AuNH2(CH2)2ImMe][AuCl4] (1) has been employed as precursor for the electrosynthesis of gold nanoparticles (AuNPs) onto ITO electrodes in 0.5moldm?

Cyclic voltammetry investigation of borohydride oxidation at a gold electrode

Sodium borohydride (NaBH4) is receiving increasing attention during the last decade regarding its possible application in energy systems. NaBH4 has the dual potential of generating hydrogen on demand or being directly oxidised in a direct borohydride fuel cell (DBFC).

Copper chloride modified copper electrode: Application to electrocatalytic oxidation of methanol

Copper chloride modified copper (CCMC) electrode was prepared as a new electrode. For the preparation of the modified electrode, the polished copper electrode was placed in 0.1M CuCl2 solution for 20s. In this step, a layer of copper (I) chloride was formed at the surface of copper electrode.
