Abstract
An improved air purification adsorbent is disclosed. The air purification adsorbent comprises titanium dioxide (TiO) impregnated with zinc chloride (ZnCl2). The adsorbent may be used in air purification systems for removing ammonia from air streams. The nanocrystalline (amorphous) structure of the adsorbent results in a higher density of surface defects, higher surface area, and higher reactivity which, when combined with the synergistic effect of ZnCland the nanocrystalline TiO, provides a significantly longer breakthrough time of ammonia as compared with breakthrough time from unimpregnated nanocrystalline TiO, the commercial (crystalline) TiOimpregnated with ZnCl, pure ZnCL, and other commercially available adsorbents of ammonia. Other embodiments are described and claimed.
