Document Type and Number:
Japanese Patent JP2669039
Kind Code:
B2
Abstract:
PURPOSE:To perform efficient photocatalytic reaction in both of air and a solution by arranging a hollow cylindrical honeycomb structure composed of a metal oxide catalyst around an ultraviolet lamp. CONSTITUTION:A hollow cylindrical honeycomb structure composed of a metal oxide catalyst 2 is arranged around an ultraviolet lamp 1. For example, the hollow cylindrical honeycomb catalyst 2 composed of titanium oxide having a thickness of 7mm, the number of cells of 200 cells/inch and a diameter of 150mm is incorporated around a mercury lamp 1. A platinum plate 3 as an opposed electrode is connected to the photocatalyst 2 by a conductor 4 and the mercury lamp 1 is arranged in a tubular quartz container 5 so as not to be directly brought into contact with an electrolyte solution 6. As a result of irradiating a 3N NaOH solution 6 with ultraviolet rays using this apparatus to perform photolysis, quantum efficiency of 0.2% is obtained.
