Methods for preparing porous inorganic coatings on porous supports using certain pore formers, and porous supports coated with porous inorganic coatings. The porous inorganic coatings may serve as membranes useful in, for example, liquid-liquid, liquid-particulate, gas-gas, or gas-particulate separation applications.
We claim: 1. A method for preparing a porous inorganic coating on a porous support, which comprises: providing a porous support comprising a first end, a second end, and a plurality of inner channels having surfaces defined by porous walls and extending through the support from the first end to the second end; applying to the inner channel surfaces of the support a coating comprising inorganic particles and an organic pore-forming material selected from protein particles, starch particles, synthetic polymer particles, and combinations thereof; and heati...
