Making a stack : Layered titanate nanosheets (see field‐emission TEM image) ≈10 nm in thickness and with a specific surface area above 400 m 2 g −1 were prepared by stacking TiO 6 monolayers and ammonium ions through a bottom‐up route in an agar matrix containing TiF 4 . Higher‐order architectures, such as spherical particles and hollow needles, were produced by self‐organized growth of the nanosheets.
