    Abstract: 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.

    Abstract: A 3D ruthenium/graphene aerogel composite loaded with MOF, preparation method thereof, and its application in continuous treatment of CO are disclosed. Using a simple solvothermal method, ruthenium is simultaneously embedded in the aerogel formation process to form a 3D ruthenium/graphene aerogel, which is freeze-dried; the dried aerogel is surface carboxylated, and the MOF material is modified on the surface by step-by-step assemble strategy, and finally the ruthenium/graphene aerogel composite loaded with MOF is obtained. Also disclosed are a simple method, and a cycle involving the simultaneous adsorption and catalytic oxidation of CO eventually formed due to the adsorption ability of MOF and the catalytic ability of catalysts. Furthermore, the adsorption of MOF can increase the instantaneous concentration of CO around the catalyst, which in turn increases the reaction rate. In particular, the product prepared by the simple method has excellent properties for catalytic CO performance.

    Abstract: Disclosed are a honeycomb-like homo-type heterojunction carbon nitride composite material and a preparation method thereof, and an application of the honeycomb-like homo-type heterojunction carbon nitride composite material in catalytic treatment of waste gas. The preparation method includes the following steps: with two different carbon nitride precursors namely urea and thiourea as raw materials, weighing certain amounts of the urea and the thiourea, adding the urea and the thiourea into a crucible, adding a certain amount of ultrapure water, placing the crucible in a muffle furnace, and carrying out calcination molding. The honeycomb-like homo-type heterojunction carbon nitride prepared by the one-step method has good photocatalytic effect to catalytic degradation of NO; meanwhile, the honeycomb-like homo-type heterojunction carbon nitride composite material has the advantages of rich and easily-available production raw materials, good stability, reusability, etc., and has application prospects in the field of treatment of NO in the air.
