PROBLEM TO BE SOLVED: To provide a tubular body of tungsten oxide which can be synthesized inexpensively in large quantities and exhibits high-level photocatalytic activity when irradiated with visible light and to provide a photocatalyst using the tubular body of tungsten oxide. SOLUTION: The tubular body of tungsten oxide consists of an aggregate of fine particles of the tungsten oxide shown by formula, WO<SB>3</SB>. It is preferable that each fine particle has 10-200 nm particle diameter and the tubular body of tungsten oxide has an outside diameter of 100 nm to 2μm, an inside diameter of 20 nm to 1μm, a length of 1-50μm and a specific surface area of≥5 m<SP>2</SP>/g. The visible light-responsive photocatalyst using the tubular body of tungsten oxide is provided. COPYRIGHT: (C)2010,JPO&INPIT |
