Abstract: The invention discloses a visible light responsive tricobalt tetraoxide dodecahedron/carbon nitride nanosheet composite and an application thereof in exhaust gas treatment. The preparation method of the composite comprises the following steps: with urea as a precursor, carrying out twice calcination to obtain carbon nitride nanosheet; dispersing the carbon nitride nanosheet into methanol, sequentially adding cobalt nitrate hexahydrate and 2-methylimidazole, and carrying out a reaction to obtain a carbon nitride nanosheet composite; and calcining the carbon nitride nanosheet composite in an air atmosphere at a low temperature to obtain the tricobalt tetraoxide dodecahedron/carbon nitride nanosheet composite. The in-situ growth synthesis method can ensure that the tricobalt tetraoxide obtained by follow-up calcination is uniformly coated on the carbon nitride nanosheet to improve the catalytic performance; the low temperature calcination ensures that the carbon nitride can maintain its wrinkle state and chemical structure during the calcination process.

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.
