    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: 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: Visible-light response hybrid aerogel and a preparation method and application thereof in waste gas processing are disclosed. Dicyandiamide is taken as a precursor and is calcined in two times to prepare a carbon nitride nanosheet; the carbon nitride nanosheet is dispersed in water, silver metavanadate quantum dots are subjected to in-situ growth to prepare a silver metavanadate quantum dot/carbon nitride nanosheet composite material; the silver metavanadate quantum dot/carbon nitride nanosheet composite material and graphene oxide carry out hydrothermal reaction, and are then frozen and dried to prepare silver metavanadate quantum dot/carbon nitride nanosheet/graphene hybrid aerogel which is the visible-light response hybrid aerogel. The problems of large reduction dosage, serious secondary pollution, complexity in operation and the like generated when waste gas is processed by a traditional flue gas denitration technology are overcome.
