Abstract
AbstractA scale‐up and sustainable method was developed to fabricate novel photocatalyst cellulose‐derived carbon aerogel@Na2Ti3O7 composite (CAT) by in situ growth of Na2Ti3O7 nanowhisker on the surfaces of fibers. With a three‐dimensional (3D) mesoporous network interconnected structure and a high specific surface area (248.92 m2/g), CAT exhibited excellent photocatalytic activity and methylene blue (MB) removal rate (98.3%). The photocatalytic experimental results showed that the CAT could degrade MB in the aqueous solution within 90 min. Compared with most reported catalysts, CAT exhibited a higher MB removal rate and shorter catalytic time. Therefore, the photocatalyst CAT based on environmentally friendly and low‐cost cellulose displayed great application potential in the degradation of MB.
