1results about How to "Lower catalytic temperature" patented technology

The application relates to the technical field of 3D printing and catalytic material preparation, and discloses a VOCs oxidation catalyst, a preparation method thereof and application of the VOCs oxidation catalyst in catalytic oxidation of VOCs. The preparation method of the catalyst comprises the following steps: obtaining an embryo with a hollow lattice structure through 3D printing; performing defatting, sintering and alkali treatment on the embryo to obtain a 3D printed ceramic carrier; loading catalyst slurry on the surface of the 3D printed ceramic carrier, and then performing drying and calcination treatment to obtain the VOCs oxidation catalyst. The VOCs oxidation catalyst is prepared through the above method, is rich in interconnected pores, has a large specific surface area and a high catalyst loading capacity, has a low catalytic temperature, and can realize catalytic oxidation of VOCs at a high air speed and a low temperature.
