Ceramic composite material, for use as a biocatalyst or biofilter, e.g. for treating polluted water, comprises biological material and nanoparticulate reinforcing material embedded in a ceramic substrate

摘要

A composite material (A) comprises a ceramic substrate (A1) in which one each of a biological material (B) and a nanoparticulate reinforcing material (C) are homogeneously embedded. An Independent claim is also included for a method for preparing (A) comprising preparation of a slip from an aqueous dispersion of (A1) and a dispersion of (B); addition of (C); solidification by neutralization of the mixture at room temperature, or by freezing, to form a composite, which is then subjected to final drying.
