Abstract: A composite filtration material is provided as well as a method for preparing the same. A filter is also provided that is fabricated with the presently disclosed composite filtration material. In various aspects, the provided composite filtration material may include activated carbon doped with silver and/or iron oxide. A one-step thermal decomposition process is provided that may be employed to prepare the provided composite filtration materials. The one-step thermal decomposition process may include dissolving one or more precursors in water, spraying the dissolved one or more precursors onto activated carbon, and heating the activated carbon saturated with the one or more precursors for a predetermined amount of time. The inventors have found that the provided composite filtration materials are more effective (e.g., higher removal of pollutants) and have a longer service life as compared to typical activated carbon filtration materials.
