ACTIVATED CARBON

PROBLEM TO BE SOLVED: To obtain an activated carbon having a photocatalystic effect even by irradiation of visible rays from an ordinary fluorescent lamp, white lamp, solar lamp, etc., by injecting metal ions having d-orbit electrons selected from V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Pt, Au into titan...

Summary:PROBLEM TO BE SOLVED: To obtain an activated carbon having a photocatalystic effect even by irradiation of visible rays from an ordinary fluorescent lamp, white lamp, solar lamp, etc., by injecting metal ions having d-orbit electrons selected from V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Pt, Au into titanium dioxide and incorporating the titanium dioxide into an activated carbon. SOLUTION: Metal tons having d-orbit electrons selected from V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Pt. Au are injected into titanium dioxide under conditions of 10 to 1000keV accelerating voltage and 1×10 to 1×10 N/cm injection amt. Then the obtd. titanium dioxide is added in the production process of an activated carbon and formed with the activated carbon into one body. The titanium dioxide used may have a rutile or anatase structure, and generally 5n anatase structure is preferable. Thereby, the ability of the activated carbon to remove harmful substances or pollutant in a liquid or gas can be largely improved.
