Research Abstract |
The main results of this research are as follows. (1) ZrO_2/carbon clusters composite materials obtained by using of phenol resin as organic-matrix showed high photocatalytic activity. The activity of the composite materials increases by the surface hydrophilization. (2) The MnO_2 or CeO_2-loaded composite materials proceeded water splitting reaction under irradiation of a visible light. (3) The visible light-responsive photocatalytic activity induced by the synergistic effect of splitization of the band structure due to O vacancy, C-dope and charge separation ability of the carbon cluster. (4) Al_2O_3 or SiO_2/carbon cluster composite materials also indicated that visible light-responsive photocatalytic activity. (5) We have succeeded in constructing composition graded-films with charge separation ability.
