Preparation method of ordered nickel cerium oxide nanorods in carbon aerogel

Abstract

The invention discloses a preparation method of ordered nickel cerium oxide nanorods in carbon aerogel. The method comprises the following steps: 1, electroplating part of nickel by an AAO template method; 2, preparing nickel oxide / cerium oxide nanorods through low-temperature sintering; 3, putting the nickel oxide / cerium oxide nanorods into the aerogel, uniformly stirring, and enabling the nanotubes to be distributed in order under a directional magnetic field; and 4, performing high-temperature carbonization to prepare the carbon aerogel containing the ordered nickel cerium oxide nanorods. The nickel-cerium oxide nanorod is prepared in a mode of combining an AAO template method and low-temperature oxidation, due to the characteristic that one end of the nickel-cerium oxide nanorod is magnetic and the other end of the nickel-cerium oxide nanorod is non-magnetic, the nickel-cerium oxide nanorod can be orderly distributed in the carbon hydrogel by applying a magnetic field with certain strength, the synthesis method is simple, and macro-scale preparation can be achieved.
