Abstract

The invention discloses a catalyst for removing volatile organic compounds and a preparation method therefor. In the catalyst, aluminum oxide modified by iron, cobalt and nickel is used as a carrier, cordierite honeycomb ceramic is used as a matrix, and an extremely low content of a mixture of platinum and palladium is used as an active component; a molar ratio of platinum to palladium is 0-1:0-9, and an amount of the mixture of platinum and palladium accounts for 0.01% to 0.05% of a mass of the matrix; and an amount of the carrier accounts for 3% to 5% of the mass of the matrix.
