The potential application of electrochemically formed copper sulfide as horseradish peroxidase mediator in the enzymatic biofuel cell and anthraquinone AV109 dye as a fuel is investigated. The open circuit voltage of 0.52 V and short circuit current of ～3.6 μA/cm^2 are obtained, with the maximum specific power of ～1 μW/cm^2. The influence of internal resistance of the cell is discussed. Decolorization is investigated under open circuit potentials, and under external load of 3.3 k conditions. In both cases, 40% of decolorization is achieved, but are three times faster under external load conditions. Specific energy during decolorization in such cell is estimated to ～5 m Wh/m^2. The possible mechanism of the power generation during decolorization of AV 109 dye is discussed.

Influence of chloride ion concentration on initial corrosion of magnesium Az63 alloy

引用

Transactions of Nonferrous Metals Society of China 2021年

作者： branimir N.GRGUR branimir z.JUGOVI? Milica M.GVOzDENOVI? University of Belgrade， Faculty of Technology and Metallurgy Institute of Technical Science， Serbian Academy of Science and Arts

The initial corrosion behavior of Az63 magnesium alloy is investigated in 1， 3， 5 and 7 wt.% NaCl by the means of corrosion potential， linear polarization， electrochemical impedance spectroscopy， and polarization measurements， during exposure in the corrosion media. Results show that increases in chloride concentrations provoke an increase in the corrosion rate. Based on the obtained kinetics parameters the mechanism of anodic dissolution and hydrogen evolution reactions are discussed， and kinetic models are proposed. It is concluded that anodic dissolution proceeds under Temkin conditions and hydrogen evolution reaction depend on the surface coverage of Mg（OH）2species.
