Abstract: A method for making a filtration article comprising coating a catalytic material within porous ceramic walls of a honeycomb filter body, thereafter depositing a filler material within the body, and exposing the body to a surface treatment to deposit inorganic deposits within the body on one or more portions of the walls, and burning off the filler material. A filtration article comprises inorganic deposits disposed on walls defining inlet channels; and a catalytic material in pores of walls. At least a portion of the inorganic deposits comprise bridging inorganic deposits which at least partially extend over the pores that extend to the surface of the walls, and such bridging inorganic deposits are spaced away from the catalytic material which is disposed within the walls. Soot treatment is used to space away the bridging inorganic particles from the catalytic material and/or substantially separate the inorganic particles from the catalytic material.

Abstract: Disclosed are a grain boundary and surface-loaded noble metal catalyst, a preparation method and an application thereof. The noble metal is dispersed at the grain boundary and surface of alumina and/or a rare earth manganese-zirconium composite oxide to form a multiphase interface, which achieves the following beneficial technical effects: firstly, the multiphase interface has a larger steric hindrance and a stronger anchoring effect, which can inhibit the migration, agglomeration, and growth of the noble metal at high temperatures, increase the high-temperature stability and catalytic performance of the noble metal, and reduce the usage of the noble metal; secondly, the multiphase interface exhibits a synergistic catalytic effect, which can reduce the activation energy of lattice oxygen and increase the quantity of active oxygen, thereby enhancing the NO oxidation and low-temperature catalytic activity.

Abstract: The present disclosure provides a honeycomb catalyst for catalytic oxidative degradation of VOCs prepared by an ultrasonic double-atomization process. The honeycomb catalyst is prepared by performing acidification and performing hydrothermal activation in alcoholic solution for honeycomb to modify a surface; dissolving soluble transition metal inorganic salt in deionized water to obtain precursor solution; performing ultrasonic atomization of the precursor solution and the precipitant solution in the ultrasonic atomization device into droplets; placing the modified honeycomb in a special quartz glass reactor, wherein the droplets enter into the quartz glass reactor through a pipeline to come into contact with a surface of a honeycomb hole and rapidly react to generate a hydroxide precursor on the surface of the honeycomb hole; drying the honeycomb into a drying box after performing the ultrasonic atomization, and calcining the honeycomb into a muffle furnace to obtain the honeycomb catalyst loaded with transition metal oxides.
