Abstract
|
|
|
|
Copper oxide (CuO) was synthesized from CuCl2 by solution method. Anatase TiO2 particle was dispersed into the solution before preparing CuO, so that TiO2/CuO heterojunction was created through the nucleation of CuO onto the TiO2 surface. Some amount of CuO was reduced to Cu2O by treating glucose into the solution, thereby preparing TiO2/CuxO complex. The obtained TiO2/CuxO complex showed advanced phtocatalytic activity under the sun light compared with the P-25 sample. In addition, the the TiO2/CuxO complex showed excellent antipathogenic effect.
