In order to improve the antibacterial activity of Zn2+, a series of Zn2+ or/and Ce3+ modified layered alpha-zirconium phosphate (ZrP) was prepared and characterized, and the antibacterial activity of the prepared Zn2+ or/and Ce3+ modified ZrP on Gram-negative Escherichia coli and Gram-positive Staphylococcus aureus was investigated. The results show that the Zn2+ or/and Ce3+ is combined with ZrP, and the d(002) basal spacing of Ce3+ modified ZrP is riot obviously changed, while the d(002) basal spacing of Zn2+ modified ZrP is increased. Zn2+ and Ce3+ modified ZrP displays excellent synergistic antibacterial activity, suggesting great potential application as antibacterial agents in microbial control.
