| 摘要 |
This invention discloses a method to prepare high-quality porous supported materials for catalytic applications, in order to achieve catalysts with both a uniform distribution of active phase and a uniform and controlled porosity, with control over pore size. One or more soluble active phase precursor is added to a slurry consisting of an insoluble support phase in water or organic solvent, the slurry is milled to reduce the particle size of the support phase to less than 50 m, processing aids are added before or after milling, a pore former is added and the slurry is spray dried, compacted and subjected to thermal treatment for removal of the pore former. |
