Surfactant-free pH-assisted facile engineering of hierarchical rutile TiO2 nanostructures by a single step hydrothermal method for water splitting application

A photoanode of distinct hierarchical pure rutile phase TiO2 nanostructures was successfully prepared by a surfactant and template-free, single-step hydrothermal route. Tuning of the morphology from compact broccoli-like structures of ∼4 μm in diameter to outsized round bottle brush flower-like structures of ∼12 μm in diameter was achieve...More
