▎ 摘  要

NOVELTY - Anti-haze-proof and degradation of formaldehyde graphene oxide/biological enzyme nano composite material is claimed. The nano composite material is obtained by (i) preparing biological enzymes by acid method, then dispersing the resultant biological enzyme into deionized water, (ii) preparing porous sponge-type three-dimensional graphene oxide, and (iii) immersing the porous sponge-type three-dimensional graphene oxide in biological enzyme solution, and the sponge-type three-dimensional graphene loaded with the biological enzyme, then drying in a drying oven at 50 degrees C to obtain final product. USE - The nano composite material is useful as mask, air purifier, air conditioner filter and in sewage treatment filter. ADVANTAGE - The nano composite material: has formaldehyde degradation ability, stable and durable effect.
