Electrodeposition of Si on substrates such as Ni, Ag and GC from acetonitrile and tetrahydrofuran containing SiCl4 and SiHCl3 as precursors is reported. The deposits readily oxidize on exposure to air but XPS analysis of a deposit withminimum contact with air confirms that elemental Si (2p, 99.5 eV) is electrodeposited. The deposits contained C, O, N and Cl impurities; annealing under argon imp...

Electrodeposition of gold into porous silicon was investigated. In the present study, porous silicon with ~100 nm in pore diameter, so-called medium-sized pores, was used as template electrode for gold electrodeposition. The growth behavior of gold deposits was studied by scanning electron microscope observation of the gold deposited porous silicon. Gold nanorod arrays with different rod length...

The environmental pollution of 2,4,6-tribromophenol (TBP) has attracted attention. Based on an urgent need for the better provision of clean water, in situ determination of TBP is of great importance. Here, a facile and effective approach for detecting TBP is developed, based on coupling molecular imprinting technique with electrodeposition of chitosan (CS) on the gold electrode. The TBP imprin...

A triboelectric nanogenerator composed of gold nanoflowers is demonstrated. The proposed triboelectric nanogenerator creates electricity by contact-separation-based electrification between an anodic metal and a cathodic polymer. For the improvement of output power via the enlargement of the effective surface area in the anodic metal, gold nanoflowers that produce a hierarchical morphology at a ...

The controlled electrodeposition of functional polydopamine (PDA) thin films from aqueous dopamine solutions is demonstrated with a combination of electrochemistry, atomic force microscopy (AFM), and surface plasmon resonance (SPR) measurements. PDA micropatterns are then fabricated by electrodeposition on micrometer length scale gold electrodes and used for attaching amino-modified single-stra...

Nanostructured network-like MnO2-NiO composite electrodes were electrodeposited onto stainless steel substrates via different electrodeposition modes, such as chronopotentiometry, chronoamperometry, and cyclic voltammetry, and then subjected to heat treatment at 300°C for metal oxide conversion. X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy...

Electrodeposition has been widely used for the low-cost formation of large-area thin films of various crystalline materials. In this work, we use thermodynamic calculations to guide electrochemical experiments, in which we conduct a systematic investigation of crystalline iron sulfides formation on electrically poised iron substrates in H2S aqueous solutions. Whereas thermodynamic calculations ...

Solar photoelectrosynthesis of methanol was driven on hybrid CuO-Cu(2)O semiconductor nanorod arrays for the first time at potentials ~800 mV below the thermodynamic threshold value and at Faradaic efficiencies up to ~95%. The CuO-Cu(2)O nanorod arrays were prepared on Cu substrates by a two-step approach consisting of the initial thermal growth of CuO nanorods followed by controlled electrodep...

Cu2O-modified ZnO nanorods are prepared by a two-step electrodeposition method on ITO substrates, and the deposition time of Cu2O is 0, 1, 5, and 10 min, respectively. Cu2O particles are embedded in the interspaces of the ZnO nanorods, and the amounts of the Cu2O particles increase obviously when the deposition time lasts longer. The peaks corresponding to ZnO nanorods and Cu2O particles are de...

Hybrid semiconductor (SC)/ ferromagnetic (FM) structures have been investigated due to the possibility of using not only the charge but also the spin of electrons to conceive new electronic devices [1-3]. In particular, ZnSe has been pointed out as one attracting candidate to achieve such goal due to their favorable chemical stability in the presence of Fe [4] and theoretical calculations sugge...
