Abstract
The invention discloses a composite material used for catalyzing and degrading nitrogen oxide and its preparation method and application thereof. The invention of the hollow g-C3N4 nanospheres/reduced graphene oxide composite-polymer carbonized nanofiber material is prepared as follow: 1) the preparation of silica nanospheres; 2) the preparation of hollow g-C3N4 nanospheres; 3) the preparation of graphene oxide; 4) the preparation of surface modified hollow g-C3N4 nanoparticles preparation; 5) the preparation of composites; 6) the preparation of composite-polymer carbon nanofiber material. The raw materials used in the process is low cost and easy to get; the operation of the invention is simple and convenient without the use of expensive equipment in the whole process; the composite has high adsorption efficiency of ppb level nitrogen oxide with good repeatability.
