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.
