Two-dimensional titanosilicate models (not DFT-optimized) as predicted by GRINSP

They can be porous too...

Models selected among 3803 CIFs including 3D and 2D titanosilicates - TiO6 octahedra or trigonal prisms connected to SiO4  tetrahedra exclusively by corner-sharing

Not exhaustive list (more will be added during the next weeks, maybe)...
