• assist the photodegradation of phenol in water under UV light illumination. The enhanced photocatalytic activity can be attributed to the significantly increased surface area and enhanced charge separation.

• surface area of the pristine TiO2 nanobelt. The further increased surface area of the branched nanostructure can be explained by the thinner thickness (≈2 nm, Figure 2d) and thus higher specific surface area of the nanosheet branches compared with the nanobelt trunks (≈5 nm in thickness, Figure 2a and
