| titleOfInvention | Preparation method of porous graphene membrane and application of porous graphene membrane in aspect of carbon dioxide capture |
| abstract | The invention discloses a preparation method of a porous graphene membrane and application of the porous graphene membrane in carbon dioxide capture, and belongs to the field of film preparation. The preparation method of the porous graphene film comprises the following steps of 1: preparation of porous alpha-Al by colloid filtration method 2 O 3 A substrate; step 2: preparation of Gd-doped CeO by ultrasonic chemical precipitation 2 The nanoparticle sol precursor of (a); and step 3: by dipping and pulling method on porous alpha-Al 2 O 3 Depositing a layer of Ce on the substrate 0.9 Gd 0.1 O 1.95 Preparing a GDC buffer layer by a precursor film through drying and rapid annealing process; and 4, step 4: coating graphene oxide suspension liquid with different concentrations on alpha-Al by using spin coating process 2 O 3 Drying the supported GDC buffer layer in an oven to obtain a graphene oxide membrane; and 5: by means of H 2 And (3) performing an atmosphere thermal reduction process to prepare the porous graphene film. The porous graphene membrane prepared by the invention has the advantages of good separation performance, good mechanical property and chemical stability, simple and convenient preparation process and low manufacturing cost, can realize the mass production of products, and has good marketization prospect. |
