Abstract
The present invention relates to a catalyst comprising manganese oxides wherein the manganese oxides comprise: MnO in an amount of 40-60 mole %, based on mole of Mn; MnOin an amount of 40-60 mole %, based on mole of Mn; and MnOin an amount of 1-10 mole %, based on mole of Mn. The present invention also relates to a method for preparing the catalysts and the use of the catalyst in an air purifier. The catalyst according to the present invention can effectively catalyze formaldehyde oxidation at ambient temperature so as to effectively remove indoor formaldehyde being present in relative low amounts.
