Abstract: An air purifier and a purifying method are provided. The air purifier includes a housing, a sterilization and ozone-generating unit, a physical filter, a first ozone-removing unit, and a cover. The housing has a sidewall and a bottom surface to define a processing space, wherein an upper end of the housing has an air inlet and the sidewall has an air outlet. The sterilization and ozone-generating unit is disposed in the processing space. The physical filter is disposed in the processing space, extends along the sidewall, and surrounds the sterilization and ozone-generating unit. The first ozone-removing unit is disposed between the physical filter and the sidewall. The cover is openably disposed at the air inlet.

Abstract: A sterilization device with dose function is provided. The sterilization device includes a sterilization container, an ultraviolet sterilization module, an ozone sensing module, a sterilization time counter, a dose controller and an ozone removal module. The ultraviolet sterilization module is disposed in the sterilization container to sterilize an article by emitting an ultraviolet light. The ozone sensing module is used to sense an ozone concentration of the sterilization container. The sterilization time counter is used to calculate a sterilization time. The dose controller is used to receive a sensing signal of the ozone concentration and a counting signal of the sterilization time to obtain an ozone dose. The ozone removal module is disposed in the sterilization container to remove or purify the ozone and reduce the ozone concentration in the sterilization container.

Abstract: A carbonized material, a device for removing ozone, and a method for removing ozone are provided. The carbonized material has at least a carbonyl-containing group, alkylol group, and carbon having sp2 hybrid orbital. In particular, the at least one carbonyl-containing group has a carbon content from 10 atom % to 30 atom %, based on the total carbon atoms of the at least one carbonyl-containing group, the at least one alkylol group, and the at least one carbon having sp2 hybrid orbital.
