Abstract
The present invention discloses a preparation method of a catalyst with white carbon black modified by Zr—Nd—O and use thereof, and belongs to the field of catalyst technologies. In the present invention, an organic solvent evaporation induced self-assembly method is used to load Zr—Nd—O onto white carbon black to obtain a mesoporous Zr—Nd—O/white carbon black catalyst. The mesoporous Zr—Nd—O/white carbon black catalyst in the present invention has high catalytic activity, contains uniformly distributed mesopores with a relatively large average aperture, and has a simple preparation process, etc.
