PROBLEM TO BE SOLVED: To provide a photocatalyst-supporting silica soot body that can efficiently use excitation light and has a high decomposing power, a manufacturing method thereof, and a high-performance air purifier, exhaust gas treatment apparatus, wastewater treatment apparatus, and water purification apparatus using the photocatalyst-supported silica soot body Provided. A photocatalyst-supporting silica soot body, wherein a photocatalyst is supported on a silica soot body formed by depositing silica glass fine particles. A silica soot body formed by depositing silica glass fine particles is immersed in a solution containing photocatalyst particles and / or a photocatalyst precursor, impregnated with the solution, and then dried to support the photocatalyst. A method for producing a photocatalyst-supported silica soot body. [Selection] Figure 2 |
