| titleOfInvention | Porous catalytic material |
| abstract | The invention relates to a porous catalytic material, and belongs to the technical field of powder. The preparation method comprises the following steps: the method comprises the steps of degumming short carbon fibers, carrying out a proper ball milling process on the degummed short carbon fibers and transition metal powder to obtain transition metal powder embedded with superfine carbon particles, and annealing in an oxidizing atmosphere to obtain porous transition metal oxide powder with partially or completely oxidized surfaces. And as an optimized process, depositing rare earth oxide inside the porous transition metal oxide powder by adopting a dipping-roasting method to obtain the rare earth porous catalytic material. The invention successfully solves the problem that the pore size and the distribution are difficult to regulate and control in the preparation process of the porous material by introducing the degummed carbon fiber as a pore distribution control agent of the porous transition metal and the oxide thereof, and the prepared catalytic material has uniform overall performance, high catalytic conversion efficiency, simple preparation process and low cost. |
