摘要： A nanocrystal-sized cerium-zirconium mixed oxide material includes at least 30% by mass zirconium oxide; between 5% to 55% by mass cerium oxide; and a total of 25% or less by mass of at least one oxide of a rare earth metal selected from the group of lanthanum, neodymium, praseodymium, or yttrium. The nanocrystal-sized cerium-zirconium mixed oxide exhibits hierarchically ordered aggregates having a d50 particle size less than 1.5 μm and a total pore volume after calcination at a temperature of 600° C. or more that is at least 0.7 cm3/g with a fraction of pores between 2 nm to 10 nm being less than 15%. The nanocrystal-sized cerium-zirconium mixed oxide material is prepared using a co-precipitation method followed by milling the dried and calcined oxide material. The nanocrystal-sized cerium-zirconium mixed oxide material forms a particulate filter that may be used in an exhaust system arising from a gas or diesel engine.

摘要： A molecular sieve material for sound absorption and a method for preparing the same are disclosed. There is a pore structure formed by mesopores with a pore size between 10 and 50 nm on a surface of the molecular sieve material, and the mesopores have a pore volume above 0.25 cm3/g. The molecular sieve material is obtained by etching and modifying a molecular sieve raw powder with an aqueous solution of an inorganic alkali. Since an alkali solution can selectively remove part of silicon elements in a skeleton structure of molecular sieve, more and more pore structures are generated in molecular sieve particles, which can increase the specific surface area and thus enhance the adsorption capacity of the molecular sieve for gases. The frequency reduction performance of the speaker can be significantly improved after the rear cavity of the speaker is filled with the molecular sieve material.
