摘要
The invention discloses a phosphorus-doped tubular carbon nitride micro-nano material and application thereof in waste gas treatment. Melamine is partially hydrolyzed into cyanuric acid through a phosphorous acid-assisted hydrothermal method to form a melamine-cyanuric acid super molecular precursor; the center of the precursor starts to be pyrolyzed under heating calcination, and thus phosphorus-doped tubular carbon nitride is obtained; the phosphorus-doped tubular carbon nitride and sodium borohydride are mixed and subjected to low-temperature calcination in an inert gas atmosphere, and defect-modified phosphorus-doped tubular carbon nitride is obtained. The defect-modified phosphorus-doped tubular carbon nitride micro-nano material has a good photocatalytic effect on catalytic degradation of waste gas; besides, the production raw materials are abundant and easy to obtain, and the phosphorus-doped tubular carbon nitride micro-nano material is good in stability and recyclable and has application prospects in waste gas treatment.
