Erratum to “Study on Photocatalytic Antibacterial and Sustained-Release Properties of Cellulose/TiO₂/β-CD Composite Hydrogel”

---

In the article titled “Study on Photocatalytic Antibacterial and Sustained-Release Properties of Cellulose/TiO₂/β-CD Composite Hydrogel” [1], there was an error in Figure 3, whereby panel b was a duplicate of panel a. The publisher apologises for this error that occurred during the production of the article, and the corrected figure is shown below as Figure 1:
