Abstract
The present invention relates to a method for producing hollow activated carbon nanofibers for activating peroxymonosulfate used in water purification; a catalyst for water purification comprising the hollow active carbon nanofibers produced by the method; and a method for purifying contaminated water using the catalyst. The production method of the present invention can easily produce hollow activated carbon nanofibers capable of rapidly purifying contaminated water by highly efficiently activating peroxymonosulfate used for water purification.
Claims5
A catalyst for purifying water, comprising:
- hollow activated carbon nanofibers for activating peroxymonosulfate, wherein the hollow activated carbon nanofibers comprise a carbon material body formed into a tubular shape in which a hollow is formed on the inside of the hollow activated carbon nanofibers, and a plurality of fine pores are formed in the body of the hollow activated carbon nanofibers, CoxMn3-xO4 is distributed in at least one of the hollow and the fine pores, and x in CoxMn3-xO4 is 1 or 2, and
- peroxymonosulfate,
- wherein activation of peroxymonosulfate by the hollow activated carbon nanofibers generates sulfate radicals (SO4−) and hydroxyl radicals (OH−).
