Mesoporous Al(OH)(3) film was generated on the Al foam body by alkali surface modification, followed by immersion in a polyol solution for 4 h at an elevated temperature in order to deposit silver nanoparticles (Ag NPs). The Al(OH)(3) porous matrix showed a significant increase in specific surface area due to the large size of the voids between flakes, which reached several tens of nanometers. After in situ three-dimensional deposition of Ag NPs by a polyol process, the Ag NPs were nucleated and grown at the surface of the mesoporous Al(OH)(3) film. The filter with Ag/Al(OH)(3) mesoporous nanocomposite film showed a good bacterial pathogen removal rate within a very short contact time compared to the untreated Al foam filter. Filters with deposited Ag/Al(OH)(3) mesoporous nanocomposite film have great potential for application as antimicrobial filters for tap water purification, wastewater treatment, and other bio-related applications.
