2018-04-05

Electrochemical processes involving self-assembled nanoparticles are currently the subject of intense research. In most studies nanoparticles are drop-cast onto an insulating barrier; however, this method has a considerable drawback in that it does not offer ...

Unified theoretical treatment of the Eirrev, CE, EC and CEC mechanisms under voltammetric conditions

10.1016/j.elecom.2018.03.011

2018-04-03

Via a thoughtful analysis it is demonstrated that the mathematical problem of the voltammetry of a simple charge transfer process of any reversibility degree at a macrointerface is totally equivalent to those of the CE, EC and CEC mechanisms such that they al...

Sunlight induced photoelectrochemical anticorrosion effect of corrosion product layers on electrogalvanized steel in simulated seawater

10.1016/j.elecom.2018.03.010

2018-03-29

It is demonstrated that the oxides and corrosion product layers not only endured the attack from aggressive environments, but also provided an additional photogenerated cathode protection to electrogalvanized steel in simulated seawater under simulated sunlig...

Cavities between the double walls of nanotubes: Evidence of oxygen evolution beneath an anion-contaminated layer

10.1016/j.elecom.2018.03.009

2018-03-22

The mechanisms of formation of porous anodic alumina and anodic TiO2 nanotubes (ATNTs) have attracted increasing attention due to the wide range of application of these materials. The field-assisted dissolution and field-assisted ejection theories are widely ...

Quantifying the turnover frequency for ethanol electro-oxidation on polycrystalline Pt in acid and alkaline media

10.1016/j.elecom.2018.03.008

2018-03-17

The turnover frequency (TOF) is conventionally used to measure activity in catalysis but is rarely used in electro-catalysis, which uses the value of the interfacial current instead. Herein, a procedure to quantify the TOF for the ethanol oxidation reaction (...

Evidence for the production of hydroxyl radicals at boron-doped diamond electrodes with different sp3/sp2 ratios and its relationship with the electro-oxidation of aniline

10.1016/j.elecom.2018.03.007

2018-03-15

In this work, the electrochemical production of hydroxyl radicals on boron-doped diamond (BDD) electrodes with different sp3/sp2 ratios was studied, together with the relationship between the level of production of hydroxyl radicals and the degradation and mi...

An all-solid-state Li-organic battery with quinone-based polymer cathode and composite polymer electrolyte

10.1016/j.elecom.2018.03.006

2018-03-14

Despite having promising Li storage properties such as multielectron reactions and fast kinetics, organic electrode materials exhibit poor cycling stability, which is partly caused by their tendency to dissolve in liquid electrolytes. In this work, an all-sol...

Kinetics of oxygen reaction and discharge/charging overvoltages of Li-O2 battery with aprotic electrolytes

10.1016/j.elecom.2018.03.005

2018-03-12

The measurement method is suggested and kinetic curves of the oxygen reaction are obtained for the first time on highly dispersed XC-72 and 20Pt/XC-72 active materials in lithium-containing aprotic electrolytes based on DMSO and TEGDME. The relationship betwe...

A rechargeable Mg2+/Li+ hybrid battery based on sheet-like MoSe2/C nanocomposites cathode
