The preparation process and antibacterial properties of mesoporous silica and mesoporous silver-loaded silica nanocomposites were studied.The surface morphology and composition of the composites were characterized by transmission electron microscopy (TEM),X-ray diffraction (XRD) and infrared spectroscopy (FT-IR).The prepared materials were detected by using three bacteria:Escherichia coli (EC),Pseudomonas aeruginosa (PA),and Staphylococcus aureus (SA).The results shown that the mesoporous silica nanoparticles had an ordered mesoporous structure with an average pore diameter of 2.879nm.The nano-silver was uniformly dispersed in the pores without any agglomeration.The mesoporous silica-loaded silver nanoparticles were stronger.The bacteriostatic effect was gradually increased as increasing the amount of silver supported.
