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 BiVO 4 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 BiVO 4 QDs. Moreover, a series of results indicated the strong connection was formed between biofiber and BiVO 4 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. Extracting cellulose fiber of bamboo to designed a novel BiVO 4 QDs/fibers composite photocatalyst via the in-situ method, which showed an enhanced stability and photocatalytic activity. Image 1 • Bamboo as the source to prepared cellulose fibers due to its abundant and short growth cycle. • A novel BiVO 4 QDs/fibers composite photocatalyst was obtained via the in-situ method. • Rich groups of natural cellulose fibers provided many sites to form the stability and distribution BiVO 4. • The mechanism of synthesis and the photocatalytic process were discussed and proposed.
