In-situ synthesis of BiVO₄ QDs/cellulose fibers composite for photocatalytic application

In this work, a biofiber was used as the natural polymer carrier to design a BiVO₄ QDs/cellulose fiber composite for photocatalytic application. The biofiber was obtained from bamboo, which was green, abundant and short growth cycle in Asia. Naturally rich groups of biofiber provided many sites to absorb the Bi³⁺ to form the uniform distribution for BiVO₄ QDs. Moreover, a series of results indicated the strong connection was formed between biofiber and BiVO₄ QDs, which could increase the stability and electron transfer. Therefore, the new composite photocatalyst exhibited better stability and effectively photocatalytic activity. Moreover, the possible mechanism of synthesis and photocatalytic were discussed, which provided insight for synthesizing photocatalytic based on biomaterials.
