Low-Temperature Oxidation Catalyst With Particularly Marked Hydrophobic Properties ForThe Oxidation Of Organic Pollutants

A method of purifying exhaust, the method comprising:

• providing an exhaust gas containing an organic pollutant;
• oxidizing the exhaust gas with a catalyst under conditions sufficient to oxidize the organic pollutant, the catalyst comprising
• a microporous noble metal-containing zeolite material, the zeolite material having less than 2 mol. % aluminium, the zeolite material being selected from zeolites of the types AFI, AEL, BEA, CHA, EUO, FAU, FER, KFI, LTL, MAZ, MOR, MEL, MTW, OFF, TON and MFI, the noble metal being selected from the group consisting of rhodium, iridium, palladium, platinum, ruthenium, osmium, gold and silver and combinations thereof;
• and
• a porous SiO2-containing binder having less than 0.04 wt % aluminium,
• wherein the catalyst has a proportion of micropores having a diameter of less than 1 nm of more than 70% relative to the total pore volume of the catalyst.
