Abstract ：
Au and AuPd arrays were deposited onto an indium tin oxide (ITO) surface by the electrochemical wet stamping method. Agarose stamp with microstructures and solution was used to electrodeposit and generate patterns of a certain thickness. Field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray analysis (EDX), and atomic force microscopy (AFM) were employed to characterize the morphology and components on the surface. Tip generation-substrate collection (TG-SC) mode and redox-competition (RC) mode of scanning electrochemical microscopy (SECM) combined with cyclic voltammetry were used to explore the electrocatalytic activity of the alloy arrays. In the study of the electrocatalysis, AuPd exhibited higher activity for the reduction of H2O2 than pure Au, but lower activity for that of ferrocenemethanol oxide (FcMeOH(+)).

Abstract ：
A poly(dimethylsiloxane) (PDMS) stamp was electrolessly plated using a cyanide-free solution. Gold nanoparticles (AuNPs) were transferred from the PDMS stamp to indium tin oxide (ITO), (3-mercaptopropyl) trimethoxysilane modified ITO (MPTMS/ITO), and an ITO substrate electrodeposited with a thin copper film (Cu/ITO). AuNPs formed well-ordered structures which were characterized by field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), and Raman spectroscopy. Microcontact printing allowed thin AuNPs films to be directly transferred from PDMS to substrate, so is a simple, fast, cheap and environmentally-friendly technique. AuNPs patterned on the ITO substrate exhibited surface-enhanced Raman spectroscopy (SERS) activity which will be investigated in subsequent studies.

Abstract ：
Gold-palladium nanoparticles (AuPd NPs) were prepared on an indium tin oxide (ITO) surface by potentiostatic electrodeposition from a mixture of two metal salts. The bulk compositions of the prepared AuPd NPs were studied by means of energy-dispersive X-ray analysis (EDX) and X-ray diffraction (XRD). The electrochemical behavior of the AuPd NPs in the sulfuric acid showed that the atomic ratio between Au and Pd could be adjusted by the composition of electrolyte and the applied potential. Field emission scanning electron microscopy (FE-SEM) images of the electrodeposits show that the morphology of the AuPd NPs was affected by the electrochemical deposition potential and deposition period. In addition, the AuPd NPs displayed good electro-catalytic activity for ethanol electro-oxidation in alkaline solution. (c) 2012 Elsevier Ltd. All rights reserved.

Abstract ：
Pd nanoparticles(NPs) electrodeposited onto indium tin oxide(ITO) surface were applied to the study of the electrocatalytic activity of ethanol. Firstly, cyclic voltainmetry and chronoamperometry were employed to study the deposition mechanism at the initial stage of Pd electrodeposition on ITO. The deposition process was irreversible which was controlled by the diffusion of [PdCl4] and the diffusion coefficient of [PdCl4](2-) was calculated to be 2. 19 x 10(-5) cm(2)/s. Comparing the current transient data at different potentials with those predicted by the instantaneous and progressive nucleation models under diffusion control, progressive three-dimensional nucleation mechanism was proposed for the nucleation of Pd on ITO at -0. 1 V. The mechanism changed to the instantaneous nucleation mode at -0. 3 V. FESEM images of the electrodeposits show that the size of Pd NPs is affected by the deposition potential and the deposition period. Secondly, the structure of Pd NPs was analyzed with XRD and the electrochemical behavior on ITO was studied in the solution of 0. 5 mol/LH2SO4, respectively. Finally, the obtained Pd NPs/ITO were applied in the electrocatalysis of 1. 0 mol/L ethanol in alkaline solution, which displayed superior electrocatalytic activity.

Abstract ：
Cyclic voltammetric and chronoamperometric methods were used to study the initial stage of Au electrodeposition on an indium tin oxide (ITO) surface. The nucleation process was controlled by the diffusion of [AuCl4](-). The cyclic voltammetry curves showed that the electrochemical reduction included two steps which were [AuCl4](-)->[AuCl2](-), and [AuCl2](-)-> Au. Only one reduction peak was observed when the scan rate was comparatively slow and this peak separated into two peaks when the scan rate was increased. This phenomenon resulted from the disproportionation of [AuCl2](-) during the electrodeposition process. Chronoamperometry also proved the two step reaction mechanism and the diffusion coefficient of [AuCl4](-) was calculated to be 1.3x10(-5) cm(2).s(-1). From the theoretical nucleation curves, an instantaneous three-dimensional nucleation mechanism was proposed for the nucleation of gold on ITO. Au electrodeposits were observed by field emission scanning electron microscopy (FE-SEM). SEM images of the electrodeposits showed that the morphology of the gold deposits was affected by the electrochemical deposition potential and time.
