A method for making a catalyst for ozone decomposition includes: adding a reducing agent into a water solution of a permanganate salt to obtain a first reaction liquid, and heating the first reaction liquid under continuous stirring to form a birnessite-type manganese dioxide; and adding the birnessite-type manganese dioxide into a water solution of an ammonium salt to obtain a second reaction liquid, and heating the second reaction liquid under continuous stirring to form the catalyst. |
