In 2013,Kjartansdottir, Cecilia Kristin; Nielsen, Lars Pleth; Moeller, Per published 《Development of durable and efficient electrodes for large-scale alkaline water electrolysis》.International Journal of Hydrogen Energy published the findings.Name: Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate The information in the text is summarized as follows:
A new type of electrodes for alk. water electrolysis is produced by phys. vapor depositing (PVD) of aluminum onto a nickel substrate. The PVD Al/Ni is heat-treated to facilitate alloy formation followed by a selective aluminum alk. leaching. The obtained porous Ni surface is uniform and characterized by a unique interlayer adhesion, which is critical for industrial application. IR-compensated polarization curves prepared in a half-cell setup with 1 M KOH electrolyte at room temperature reveals that at least 400 mV less potential is needed to decompose water into hydrogen and oxygen with the developed porous PVD Al/Ni electrodes as compared to solid nickel electrodes. High-resolution scanning electron microscope (HR-SEM) micrographs reveal Ni-electrode surfaces characterized by a large surface area with pores down to a few nanometer sizes. Durability tests were carried out in a com. produced bipolar electrolyzer stack. The developed electrodes showed stable behavior under intermittent operation for over 9000 h indicating no serious deactivation in the d. of active sites. The experimental process involved the reaction of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Name: Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate)
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. Name: Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate As a Biuret reagent, it is used to measure the protein concentration. Furthermore, it is used as laxative and is also used in food industry.
