Abstract

In the present study, TiO_2 imbedded copper matrix powders have been successfully prepared from the (CuSO_4+TiO_2+Zn) composite salt solution. The composite Cu/TiO_2 powders were formed by drying the solution at 200sim~400°C in the hydrogen atmosphere. Photocatalytic characteristics was evaluated by detecting TOC (total organic carbon) amount with TOC analyzer (model 5000A Shimadzu Co). Phase analysis of Cu/TiO_2 composite powders was carried out by XRD, DSC and powder size was measured with TEM. The mean particle size of composite powders was about 100 nm and a few zinc and copper oxide phases was included. The reduction ratio of TOC amount was 60% by the composite Cu/TiO_2 powders under the UV irradiation for 8 hours.
