Polyaniline-derived carbon-doped boron nitride material as well as preparation method and application thereof

The invention belongs to the field of functional material preparation, and particularly relates to a polyaniline-derived carbon-doped boron nitride material and a preparation method and application thereof.The polyaniline-derived carbon-doped boron nitride material is prepared by the steps that a very small amount of polyaniline serves as a carbon precursor, the polyaniline and a boron nitride precursor are subjected to high-temperature calcination, and carbon is doped into boron nitride in situ to form carbon-doped boron nitride; the carbon-doped boron nitride material has two active sites, namely B-N-C and pyridine nitrogen, and the number of the active sites is further increased due to the ultrathin porous structure of the carbon-doped boron nitride material, so that the carbon-doped boron nitride material can efficiently activate PMS to catalytically degrade pollutants, and when the carbon-doped boron nitride material activates the PMS to degrade sulfadiazine, under the condition of no additional energy i
