文摘

A generalized method of fabricating robust and metal-free graphene–dyes 3D aerogel photocatalysts is developed. 3D aerogels show higher dye-sensitized activity and long-term stability than powder systems. The photoactivity of aerogels can be regenerated easily by replenishing fresh dyes. Advantages of the 3D aerogels over their powder counterparts are disclosed. The work opens a new doorway to designing novel metal-free visible light photocatalysts.
