Title:
担持型二酸化チタン触媒及び該触媒を用いた芳香族化合物の酸化方法
Document Type and Number:
Japanese Patent JP4017851
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a photocatalyst useful for efficiently oxidizing an aromatic compound. SOLUTION: The supported type titanium dioxide catalyst is obtained by supporting titanium dioxide fine particles on the surfaces of rutile type titanium dioxide particles in a dispersed state. In this catalyst, it is preferable to support titanium dioxide fine particles with a specific surface area of 30 m<2> /g or more on the surfaces of the rutile type titanium dioxide particles in a dispersed state. The ratio of the titanium dioxide fine particles supported on the surfaces of the rutile type titanium dioxide particles in a dispersed state and the rutile type titanium dioxide particles is, for example, former/latter (weight ratio) = about 0.1/99.9-99.5/0.5.
