▎ 摘　　要

NOVELTY - Porous catalytic honeycomb comprises insulating honeycomb (1), catalytic layer (2) and electronic slurry. The insulating honeycomb is provided with multiple of through holes, and first end face and second end face located at both ends of the plurality of through holes. The through hole (3) form airflow channel. The inner surface of each through hole is coated with the catalytic layer. The catalytic layer contains catalyst capable of producing active substances that decompose pollutant molecules under the action of high-voltage electric field and/or light field. The electronic paste is coated on first end surface and the second end surface of insulating honeycomb, first conductive region (4) is formed by the electronic paste coated on the first end surface, and forming second conductive region (5) from the electronic paste coated on the second end face. Both the volume resistivity of the first conductive region and the second conductive region are less than or equal to 100 Ω×cm. USE - The honeycomb is useful for high-voltage electric field collaborative purification module. ADVANTAGE - The honeycomb: omits macroscopic metal electrodes; has simple structure and high installation and maintenance efficiency; can overcome the defects of complex structure, difficult assembly and disassembly; and has influence of final performance due to easy corrosion and pulverization of macroscopic electrodes existing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the porous catalytic honeycomb. DESCRIPTION OF DRAWING(S) - The drawing shows a three-dimensional structure schematic diagram of the porous catalytic honeycomb. 1Insulating honeycomb 2Catalytic layer 3Through-hole 4First conductive region 5Second conductive region 6First connection bonding pad 7Second connection bonding pad
