Three different carbon-based counter electrodes are investigated in light of catalytic activities such as electrochemical frequencies and interface impedances. We fabricated carbon-based counter electrodes of dye-sensitized solar cells [DSSCs] using graphene, single-walled carbon nanotubes [SWNTs], and graphene-SWNT composites by electrophoretic deposition method. We observed the optical and el...

Polyaniline (PANI) was successfully combined with 3DNC as supercapacitor electrodes by two commonly used method: chemical polymerization (CP) and electrochemical deposition (ECD). The combination of PANI and the 3DNC led to a fascinating result, showing high specific capacitance of 615 F/g (CP) and 1120 F/g (ECD) at the current density of 10 A/g. Both electrodes showed stable electrochemical pe...

An approach has been developed to produce silver nanoparticles (AgNPs) rapidly on semiconductor wafers using electrochemical deposition. The closely packed AgNPs have a density of up to 1.4 × 1011 cm-2 with good size uniformity. AgNPs retain their shape and position on the substrate when used as nanomasks for producing ultrahigh-density vertical nanowire arrays with controllable size, making it...

We present an electrochemical route to prepare nanocrystalline InSb thin films that can be transferred to an industrial scale. The morphology, composition, and crystallinity of the prepared uniform and compact thin films with a surface area of around 1 cm were investigated. The essential electrical characteristics such as conductivity, Seebeck coefficient, the type, concentration and mobility o...

Controllable preparation of nanopores to promote the performance of electrochemical biosensing interfaces has become one of the researching frontiers in biosensing. A double biocatalysis signal amplification of glucose biosensor for the study of electrochemical behaviors of glucose oxidase (GOx) was proposed by using horseradish peroxidase biosynthesized porous graphene (PGR) as the platform fo...

Anode materials of nanostructured silicon have been prepared by physical vapor deposition and characterized using electrochemical methods. The electrodes were prepared in thin-film form as nanocrystalline particles ~12 nm mean diameter! and as continuous amorphous thin films ~100 nm thick!. The nanocrystalline silicon exhibited specific capacities of around 1100 mAh/g with a 50% capacity retent...

This paper reviews the chemical and electrochemical depositions of platinum group metals (PGMs) from aqueous solutions. With a brief introduction on the fundamental aspects of chemical/electrochemical depositions, the review describes recent advances in chemical and Abbreviations: CD, cathode current density expressed as amperes per cm2; CE, cathode current efficiency; dc, direct current; DMFC,...

The current study investigates the energy consumption and corresponding global warming potential (GWP) of tellurium recovery from multimetal solution by use a tailored electrochemical approach based on electrodeposition-redox replacement (EDRR). A three-electrode cell was used to recover Te synthetically prepared pregnant leach similar PLS leached Doré slag (30% aqua regia, [Cu] = 3.9 g/L, [Bi]...
