Abstract: PURPOSE: Disclosed is a honeycomb monolith catalyst for the elimination of VOCs, which is characterized in that a hydrophobic zeolite being supported with palladium ion (Pd¬2+) and transition metals is mixed with a binder, and then washcoated on a cordierite honeycomb monolith. This honeycomb monolith catalyst shows an excellent catalytic activation at a temperature range of 260deg.C or lower, especially even in the presence of excess moisture. CONSTITUTION: This honeycomb monolith catalyst is prepared by supporting metal salts comprising palladium ion and transition metals such as Cu, Mn, Ni, Cr, and Co on a hydrophobic zeolite selected from USY-zeolite(SiO2/Al2O3=10 - 1000), ZSM-5 zeolite (SiO2/Al2O3=20 - 1000); adding a binder selected from bentonite, silica colloid, and methylcellulose for obtaining slurry-phase catalyst; washcoating prepared slurry-phase catalyst on a cordierite honeycomb monolith. In this method, palladium ion of 0.1 to 2.0wt.% and transition metal of 5 to 30wt.% (based on the weight of hydrophobic zeolite) are supported on the hydrophobic zeolite respectively, and it is characterized in that the amount of palladium and the amount of transition metal applied on the cordierite honeycomb monolith are respectively 0.03 to 0.8g/L-honeycomb and 2.0 to 15.0g/L-honeycomb.
