摘要:
Ceramic nanofibers contain nanosize metal catalyst particles on the surface thereof. The catalyst-ceramic nanofibers when supported as by larger fibers form a medium that effectively catalyze various reactions as in fluid flow processes.
摘要:
The present invention relates to a catalyst-containing nanofiber composition, comprising a ceramic nanofiber having a plurality of metal catalysts wherein the metal catalysts exist as dispersed particles partially embedded in the nanofiber and cover from about 1% to about 90% of the surface area of the ceramic nanofiber.
摘要:
Fiber webs which are used in filter media are described herein. In some embodiments, the fiber webs include fibrillated fibers and optionally non-fibrillated fibers, amongst other optional components (e.g., binder resin). In some embodiments, the fiber webs include limited amounts of, or no, glass fiber. The respective characteristics and amounts of the fibrillated fibers are selected to impart desirable properties including mechanical properties and filtration properties (e.g., dust holding capacity and efficiency), amongst other benefits.
