• twins are commonly observed in BaTiO3 [31] and CaTiO3 [32]. Conclusion A sodium-doped brookite NaxTi1−xO2 was synthesized in NaOH solution. It exhibits an excellent photocatalytic activity, three times higher than that of the quasi-spherical brookite TiO2. Results of X-ray diffraction indicate that

• [26]. This general process has also been observed for the broader class of transition metal oxides, such as CaTiO3 or BaTiO3. The titanium monoxide surface layer crystallizes in the form of nanowires oriented along the main crystallographic directions of SrTiO3(100), with a length of up to 10 µm, a

• )–CaTiO3 (CTCN) organic–inorganic heterojunction photocatalyst was synthesized by a facile mixing method, resulting in the deposition of CaTiO3 (CT) nanoflakes onto the surface of g-C3N4 nanosheets. The photocatalytic activity of the as-synthesized heterojunction (along with the controls) was evaluated by

• between g-C3N4 and SrTiO3 [34]. Thus, wide band gap materials can play an important role in maximizing the photocatalytic activity of g-C3N4 by suppressing the photogenerated charge recombination. CaTiO3 (CT) is a well-known titanium-based perovskite material with a wide band gap of ≈3.5 eV and its
