Beschreibung
Zusammenfassung:	The invention discloses a nitrogen-doped titanium dioxide (N-TiO2)/biomass charcoal (BC)-polypropylene (PP) composite melt-blown non-woven material for photocatalytic degradation and adsorption of organic dye in a water body and a preparation method thereof, and the preparation method comprises the following steps: firstly, preparing TiO2 by a sol-gel method, then mixing urea and TiO2 according to a certain proportion, then carrying out high-temperature calcination to prepare N-TiO2, and finally, carrying out high-temperature calcination on the N-TiO2 to prepare the nitrogen-doped titanium dioxide (N-TiO2)/biomass charcoal (BC)-polypropylene (PP) composite melt-blown non-woven material. The waste bagasse is used as a raw material, and the BC is prepared by a high-temperature calcination method. And secondly, mixing N-TiO2 and BC according to a certain proportion, uniformly dispersing the mixture in an absolute ethyl alcohol solution, putting the fully washed PP melt-blown non-woven material into the absolute
