Abstract: PURPOSE: A method for manufacturing an ultrafine nanoporous alumina structure is provided to form an alumina structure having nanopores by anodizing aluminum at the temperature more than or equal to 100°C using an organic electrolyte. CONSTITUTION: A method for manufacturing an ultrafine nanoporous alumina structure uses a base metallic material as an anode (200) and platinum as a cathode (300). The base metallic material is aluminum and is immersed in an electrolyte containing metal salt. The method includes a step of anodizing the surface of the base metallic material by applying voltages to the anode and cathode. The electrolyte is an organic electrolyte, and the temperature of the electrolyte is in the range of 120-220°C. The pore sizes of an alumina structure are in the range of 1-30 nm. The metal salt is phosphate. The electrolyte is glycerol or ethylene glycol. The metallic base material undergoes a washing, polishing, and drying operation prior to the anodizing step.
