Title:
【発明の名称】オゾン分解用触媒およびその製造方法
Document Type and Number:
Japanese Patent JP3091761
Kind Code:
B2
Abstract:
PURPOSE:To inhibit water absorption properties and to prevent deterioration of catalytic performance and strength by forming a catalyst which is made of activated manganese dioxide and fluororesin and constituted of high-density granular bodies having >=1.5g/cc bulk sp. gr. and >=30m<2>/g specific surface area. CONSTITUTION:A mixture is prepared by kneading activated manganese dioxide, a polyfluoroethylene-based binder and pure water. A catalyst for decomposing ozone is obtained by molding this mixture into granular bodies and thereafter calcining or drying the granular bodies at <=400 deg.C. The obtained catalyst is made of activated manganese dioxide and fluororesin and constituted of high- density granules having >=1.5g/cc bulk sp. gr. and >=30m<2>/gr specific surface area. This catalyst for decomposing ozone is good in initial performance and excellent in durability without almost deteriorating the removal percentage of ozone after the lapse of a long time.
