In 2014,Kjartansdottir, Cecilia; Caspersen, Michael; Egelund, Sune; Moeller, Per published 《Electrochemical investigation of surface area effects on PVD Al-Ni as electrocatalyst for alkaline water electrolysis》.Electrochimica Acta published the findings.Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate The information in the text is summarized as follows:
A thermo-chem. diffusion of vapor deposited Al onto a Ni substrate, leads to a rapid formation of an Al/Ni intermetallic layer that is particularly acceptable for dissolution of Al in strong alkali. The geometry and the structure of the final skeletal Ni coatings can be manipulated by altering the time interval of the diffusion. In that way the actual electrochem. surface area and, thus, the electrocatalytic activity of the coatings towards HER and OER can be influenced. Cyclic voltammetry (CV) and electrochem. impedance spectroscopy (EIS) studies, display that the electrocatalytic surface area increases in proportion to the thickness of the developed porous Ni structure. In the case of the HER, an increase in roughness factor (Rf) from 1 (for polished Ni) to 800, results in reduction of the H overpotential of 337 mV. When further increasing Rf, up to >2000, addnl. 40 mV are gained. For the OER, smaller roughness values were observed with the same activity trend as for the HER. The electrocatalyst are however found not to be stable in the anodic environment during electrolysis. The corrosion mechanism of a skeletal Ni electrocatalyst during the OER in an alk. environment is briefly discussed. The structure and composition of the electrocatalysts are characterized by SEM and x-ray diffraction. The actual electrocatalytic surface area and the electrocatalytic behavior were studied with potentiodynamic polarization, CV and EIS. In addition to this study using Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate, there are many other studies that have used Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate) was used in this study.
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Safety of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate It may be used as a constituent to prepare DNS (3,5- dinitrosalicylic acid) reagent and Fehling′s solution B, which are used in the determination of reducing sugar.
