説明

<jats:title>Abstract</jats:title><jats:p>Black liquor, an industrial waste product of papermaking, is primarily used as a low‐grade combustible energy source. Despite its high lignin content, the potential utility of black liquor as a feedstock in products manufacturing, remains to be exploited. Demonstrated here in is the use of black liquor as a primary feed‐stock for synthesizing graphene quantum dots that exhibit both up‐conversion and photoluminescence when excited using visible/near‐infrared radiation, thereby enabling the photosensitization of ultraviolet‐absorbing TiO<jats:sub>2</jats:sub> nanosheets. In addition, these graphene quantum dots can trap photo‐generated electrons to realize the effective separation of electron‐hole pairs. Together, these two processes facilitate the solar‐powered generation of H<jats:sub>2</jats:sub> from H<jats:sub>2</jats:sub>O, and CO from H<jats:sub>2</jats:sub>O–CO<jats:sub>2</jats:sub>, using broadband solar radiation.</jats:p>
