Manganese oxide-coated TiO2 nanotube array (NTA) was synthesized and applied for the (electro) catalytic oxidation of sulfide. By setting electrodeposition parameters calcination temperature, coating obtained MnO2 or Mn2O3, with rod needle like morphology. Excellent activity Ti/TiO2 NTA/MnxOy anodes resulted in robust selective sulfide to elemental sulfur via an inner sphere complex between ion...

A novel three-dimensional network nickel foam/PbO2 combination electrode (PbO2-NF) with high electrochemical degradation efficiency to norfloxacin was successfully fabricated through the electrodeposition of PbO2 on substrate foam. The characterization an PbO2-NF electrode, including surface morphology, elemental components, performance, and stability performed. In oxidation tests, removal (ini...

Lithium (Li) metal has been considered a promising anode material for high-energy-density rechargeable batteries, but its utilization is impeded by the nonuniform electrodeposition during charging process which leads to poor cycling life and safety concerns. Thus, understanding mechanism of Li-metal great importance develop practical engineering strategies batteries. The Li controlled both ther...

The objective of this work is to study the effect of two key factors external magnetic field and applied current density during template-based electrodeposition of nickel nanowires using an electrode distance of 20 mm. Morphology, length, crystallite size and crystallographic characterization of the grown nickel nanowires at an electrode distance of 20mm are presented. For this electrode distan...

Nanoscale particles offer a variety of interesting properties, and there is growing interest in their assembly into higher ordered structures. We report that the pH-responsive aminopolysaccharide chitosan can mediate the electrodeposition of model nanoparticles. Chitosan is known to electrodeposit at the cathode surface in response to a high localized pH. To demonstrate that chitosan can mediat...

Electrodeposition is a widely used materials-deposition technology with a number of unique features, in particular, the efficient use of starting materials, conformal, and directed coating. The properties of the solvent medium for electrodeposition are critical to the technique's applicability. Supercritical fluids are unique solvents which give a wide range of advantages for chemistry in gener...

Growing demand for rechargeable batteries with higher energy densities has motivated research focused on enabling the lithium metal anode. A prominent failure mechanism in such is short circuiting due to uncontrolled propagation of protrusions that often have a dendritic morphology. In this paper, electrodeposition metallic through rigid polystyrene-b-poly(ethylene oxide) (PS-b-PEO or SEO) bloc...

An amperometric acetone sensor was developed by using an electrodeposited Pb electrode in a sodium tartrate electrolyte. The major factors determining the electrode and sensing characteristics such as the applied potential, electrodeposition current density, electrodeposition temperature, agitation rate, and sensing temperature were explored. The best conditions for preparation of the electrode...

This paper presents the study of dynamic electrical resistance of the electrodeposition cell during the growth metallic dendrites showing fractal character. The electric resistance of the circular electrodeposition cell is measured in real time using a computer based data acquisition system. The data acquisition system constructed is capable of measuring the cell voltage and the current through...

We generalize the conditions for stable electrodeposition at isotropic solid-solid interfaces using a kinetic model which incorporates the effects of stresses and surface tension at the interface. We develop a stability diagram that shows two regimes of stability: a previously known pressure-driven mechanism and a new density-driven stability mechanism that is governed by the relative density o...
