Nano scrubbers

Mats containing nanoscopic fibers of metal oxide are much more efficient at scrubbing (removing) sulfur compounds from petroleum-based fuels, according to a study at the University of Illinois. The materials are much more effective than conventional scrubbers and could improve performance for fuel-based catalysis as well as making cleaner city fuels less expensive for drivers. The nanofiber mat is more reactive than its bulk counterpart, allowing complete sulfur removal with less material. The material remains stable and active for several cycles as well as precluding sintering, or clumping, of the catalyst which is a problem with other nano-structured catalysts.
