Electrolysis of Co(2+) in phosphate, methylphosphonate, and borate electrolytes effects the electrodeposition of an amorphous highly active water oxidation catalyst as a thin film on an inert anode. Electrodeposition of a catalytically competent species immediately follows oxidation of Co(2+) to Co(3+) in solution. Methylphosphonate and borate electrolytes support catalyst activity comparable t...

A patterned coreeshell tin (Sn) nanorod anode is fabricated by pulse electrodeposition of Sn onto a selfassembled Tobacco Mosaic Virus (TMV) structured nickel current collector. Pulse electrodeposition onto the virus assembled 3D electrode surfaces produces homogenous Sn coatings with significant void space to accommodate the large volume change associated with Sn lithiation. The TMV enabled 3D...

Lithium metal has gravimetric capacity ∼10× that of graphite which incentivizes rechargeable Li metal batteries (RLMB) development. A key factor that limits practical use of RLMB is morphological instability of Li metal anode upon electrodeposition, reflected by the uncontrolled area growth of solid-electrolyte interphase that traps cyclable Li, quantified by the Coulombic inefficiency (CI). He...

Deterioration of reinforced concrete members and their repair methods have been reported in various concrete published reports. Electrodeposition method is one of these repair methods for repairing deteriorated concrete members using an electrochemical mechanism. The purposes of the electrodeposition method are to fill cracks in concrete and to coat the concrete surface by electrodeposits of ch...

Cu ion was electrodeposited potentiostatically in 0.05 M CuSO4 aqueous solutions onto a foreign substrate of TiN film sputtered on a stainless steel sheet. The amount of electricity was limited to 31.8 mC cm , which corresponds to a 10 nm thick film, deposited uniformly without any void formation. Two different electrolytic cell configurations were designed in order to discuss quantitatively th...

PtRu/Ti anodes with varying Pt ratio Ru ratio were prepared by electrodeposition of a thin PtRu catalyst layer onto Ti mesh for a direct methanol fuel cell (DMFC). The morphology and structure of the catalyst layers were analyzed by SEM, EDX and XRD. The catalyst coating layer shows an alloy character. The relative activities of the PtRu/Ti electrodes were assessed and compared in half cell and...

The rates of Cu deposition from aqueous solutions containing chelating agents, such as citric acid, nitrilotriacetic acid (NTA), and ethylenediaminetetraacetic acid (EDTA), in an electrochemical membrane cell were measured. An equimolar solution of chelating agents and metals was examined. The iridium oxide and Pt coated on titanium electrodes were used as the anode and cathode, respectively. T...

Abstract Titanium diboride (TiB 2 ) is considered a promising material for wettable cathodes in aluminum electrolysis. The demand associated with the development of inert anode technologies to eliminate CO emissions caused by conventional reduction process. has been given special attention due its superior properties, such as high wettability, good electrical conductivity, wear resistance, and ...

Aqueous Zn-based batteries are attractive because of the low cost and high theoretical capacity Zn metal anode. However, developed so far utilize an excess amount (i.e., thick anode), which decreases energy density whole battery. Herein, we demonstrate anode-free design zero-excess Zn), is enabled by employing a nanocarbon nucleation layer. Electrochemical studies show that this allows for unif...
