The invention discloses a high-throughput ceramic support, a preparation method and application thereof. The preparation method includes the following steps: step 1, preparing ceramic slurry and sacrificial layer slurry; step 2, adopting double-layer casting The method is to cast the ceramic slurry and the sacrificial layer slurry on the substrate, wherein the ceramic slurry is on top and the sacrificial layer slurry is on the bottom; step 3, the casted slurry is transferred to a curing agent for phase inversion curing, and then drying at room temperature; step 4, hot pressing the two layers of precursors together top-to-bottom; step 5, sintering the hot-pressed ceramic support body at a high temperature to form a porous ceramic support body. The ceramic support obtained by the invention has a "non"-shaped structure, has a large number of finger-shaped pores on the upper and lower surfaces, has the characteristics of high porosity, high flux, high strength, and is easy to load other functional materials, and is suitable for separation membrane supports and The catalyst carrier has high application prospects in membrane separation, catalysis and other fields. |
