▎ 摘　　要

NOVELTY - Attaching graphene photocatalyst on stone surface involves washing substrate using acetone, deionized water and clean water for 15-30 minutes and then drying at 40-50 degrees C for 0.5-1 hour, adding concentrated sulfuric acid and hydrogen peroxide and then processing for 30 minutes, washing using clean water, storing using anhydrous ethanol solution, adding graphene photocatalyst powder and then heating at 45-60 degrees C, adding 0.2-3 wt.% aluminum-based crosslinking agent solution and 0.1-2 wt.% polyanionic cellulose solution and naturally drying at 50-70 degrees C for 20-30 hours. USE - The method is useful for attaching graphene photocatalyst on stone surface. ADVANTAGE - The method is capable of attaching graphene photocatalyst on stone surface in simple manner.
