PHOTOCATALYST-GRAPHENES-CARBON NANO-FIBER COMPOSITE AND FILTER COMPRISING THE SAME

摘要

PURPOSE: A photocatalyst-graphene-carbon nanofiber composite and a filter comprising the same are provided to increase activity of a photocatalyst by spraying nanosized photocatalyst particles on the surface of the composite and to catch elections moving from the photocatalyst by using graphene. CONSTITUTION: A photocatalyst-graphene-carbon nanofiber composite comprises graphene, thereby having high photocatalytic activity not only in an ultraviolet range but also in a visible light range. A photocatalyst included in the composite has a particle size of 20-50 nm and is uniformly dispersed on the surface by reacting with the surface of the composite. The photocatalyst included in the photocatalyst-graphene-carbon nanofiber composite is chosen from a group of ZnO, WO3, SnO2, ZrO2, and TiO2.
