METHODS AND MATERIALS FOR ELECTROPLATING ALUMINUM IN IONIC LIQUIDS

摘要

A method of depositing aluminum onto a substrate is disclosed. In this method, the substrate is disposed as cathode in an electrochemical cell with an anode and a liquid electrodeposition composition comprising an ionic liquid and a source of aluminum, and aluminum is electroplated onto the substrate. Residual water content in the electroplating bath is controlled by exposure to light in the presence of a photo-oxidation catalyst to decompose the water or species associated with water.
