Abstract: The catalyst supported on the porous ceramics was studied for the fume exhaust disposal of cooking fumes. The porous ceramics was prepared from ordinary ceramic powder as raw material with addition of an appropriate amount of pore forming material (sawdust) and the high temperature adhesives (sodium silicate). The main catalytic components contained Cu,Mn,Ni,Ag and Pd. The catalytic performances of the porous ceramics with catalytic components loaded were examined by XRD, SEM and TPR.

Key words: diatomite, porous ceramic, catalyst, kitchen fume
