The metal organic framework material Cu 3 (btc) 2 ·3H 2 O (HKUST‐1) was grown on differently activated oxide‐bonded SiC ceramic foams with varying pore sizes. Activation was performed by an alkaline etching procedure under dissolution of the SiO 2 binder phase in the ob‐SiC microstructure leading to an increase in strut surface roughness. The influence of foam pore size, etching conditions (duration, temperature) and the effect of a subsequent alumina coating to increase the coverage with –OH moieties was studied. The activated foams and MOF@ob‐SiC composites were characterized by microstructural analysis, H 2 O adsorption and thermal conductivity measurements.
