a, b, ETS-10 is a nanoporous titanosilicate with a structure consisting of five tiles (a) connected in a monoclinic lattice (b). c, The structure has a very similar symmetry to zeolite β; however, the titanium is incorporated into titania rods surrounded by silica.

directions and are found to be the dominant components for the crystal growth. f, Because the rods do not always connect and heal inside the crystal structure, there is a high concentration of internal silianol groups in a sector from the (001) faces to the centre of the crystal. Such sectoring in ETS-10 has been observed in Raman microscopy24. Supplementary Video 5 demonstrates how the rods in the ETS-10 framework grow in alternating orthogonal directions. The simulated crystals shown in d and f are approximately 0.25 μm × 0.25 μm × 0.05 μm and 0.10 μm × 0.10 μm × 0.10 μm in size, respectively; ΔUs = 2 kcal mol−1.
