Insight at the atomic scale of corrosion inhibition: DFT study of 8-hydroxyquinoline on oxidized aluminum surfaces

Abstract

8-hydroxyquinoline (8-HQ) is a promising organic molecule for the replacement of chromate salts used to improve the corrosion resistance of aluminum and its alloys. A better understanding of the molecule-surface...

Properties and composition of the spent electrolyte for premium circulation mediated by Al–air batteries

“…1 As an energy storage medium, Al holds the most outstanding theoretical volumetric capacity (8046 mA h cm À3 ) and high gravimetric capacity (2980 mA h g À1 ), which ranks only second to Li (3861 mA h g À1 ). 2,3 Among aluminum batteries, the Al-air battery (AAB) is a device composed of a metal Al anode, an air-breathing cathode and an aqueous electrolyte. AABs take full advantage of aluminum to realize the efficient conversion of chemical energy to electrical energy.…”
