▎ 摘　　要

NOVELTY - The material has a graphene coated on a surface of a porous material main body e.g. sponge or cloth-like materials. A catalyst thermally catalyzes degradation of formaldehyde supported in the porous material main body, where Graphene content of the porous material main body is 0.035 to 0.055mg/cm3. USE - Electrically conductive porous material. ADVANTAGE - The material can rapidly reach temperature required for thermal catalytic degradation of formaldehyde so as to achieve in-situ heating catalytic effect, thus greatly reducing heat loss caused by heat conduction, and has simple structure, strong processability and low production cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) an in-situ Joule heat catalyst degradation formaldehyde method (2) an in-situ Joule heat catalyst degradation formaldehyde device. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of an electrically conductive porous material.
