| Summary: | Synchrotron‐based small‐ and wide‐angle X‐ray scattering is used to elucidate the structure of low‐dimensional lepidocrocite–titanate‐based nanofilaments. In the colloidal state, they consist of quantum‐confined 1D NFs, loosely associated into nanoribbons, one lepidocrocite sheet thick (about 4 Å), 30–40 Å wide (5–8 NFs), and more than 300 Å long. In the dry state, they reach a final state of extended sheets, stacked three to about twenty high, whose crystallinity increases with stack height, in parallel with a decrease in photocatalytic activity. These findings suggest a kinetic pathway for the self‐assembly of initially 1D titanate nanoribbons into 2D and ultimately 3D structures, providing context for a recent body of work on these low‐dimensional materials. |
