In this paper, antibacterial agent of silver-carrying nano-hydroxyapatite is synthesized by an ion exchange reaction, which is mixed thoroughly with a commercial glaze for antibacterial ceramics. The valence states of Ag in antibacterial agent are confirmed to be +1 and 0 by XPS. Antibacterial effect against bacterium of E. coli is also tested. Experimental results indicate that the antibacterial ceramics exhibit excellent antibacterial performances, with bactericidal rate of 99.92%.

Ion Exchange Reaction

The formation of reactive oxygen species due to irradiation by a visible light of the polythiophene deposited in ZSM-5 zeolite channels in aqueous medium has been studied. Polymerization of thiophene was carried out in zeolite channels after the ion-exchange reaction of Na+ for Fe3+. By means of EPR spectroscopy, the temporarily generated 1O2 in irradiated aqueous medium was proved. The formation of O2-• was confirmed by the reduction of Fe3+-cytochrome c. Irradiation led to the water reduction to hydrogen.
