dc.description.abstractMacrocellular calcium silicate (wollastonite) ceramic foams possessing similar to 86 vol% total porosity were produced from commercial calcium silicate hydrate (xonotlite) nano-size acicular crystals and poly-methyl-methacrylate microbeads (PMMA) (used as sacrificial pore formers). Open cell wollastonite foams had a bi-modal pore size distribution with major modes located similar to 100 nm due to interparticle porosity and similar to 100 mu m due to the sacrificial pore former. These macrocellular ceramics were then used as a scaffold for MFI type zeolite (silicalite-1) synthesis. Monolayer coffin shaped zeolite crystals (similar to 3 mu m size, measured from the c-axis and similar to 300 nm thickness) were observed with almost full coverage on the inner macro-cell walls. The specific surface area of the components increased from 9.6 m(2)/g to 108.2 m(2)/g via zeolite functionalization, leading to components possessing multiscale porosity.
