Mesocrystal precursor transformation strategy for synthesizing ordered hierarchical hollow TiO2 nanobricks with enhanced photocatalytic property

TiO2 mesocrystals built of nanocrystals with exposed {001} facets: facile synthesis and superior photocatalytic ability

“…[16][17][18] Their unique structure may optimize the relationship between crystallite size and specic surface area. [19][20][21][22][23][24][25] Most of them are built of TiO 2 nanocrystals with rarely exposed {001} facets.

Top-Down Synthesis and Deposition of Highly Porous TiO 2 Nanoparticles from NH 4 TiOF 3 Single Crystals on Multi-Walled Carbon Nanotubes and Graphene Oxides

“…In general, the synthesis of NH 4 TiOF 3 mesocrystals is surfactant-mediated. In contrast, some research groups have recently demonstrated a surfactant -free method for synthesizing NH 4 TiOF 3 mesocrystals from a sol-gel precursor [16,17]. However, such syntheses are generally achieved by a solvent-thermal reaction at high pressure and high temperature.…”

Titanium Dioxide (TiO2) Mesocrystals: Synthesis, Growth Mechanisms and Photocatalytic Properties

“…Such a topotactic transformation could proceed mainly because of the crystal structure similarity between NH 4 TiOF 3 and anatase TiO 2 crystals (less than 0.02% in an average lattice mismatch), and the as-synthesized NH 4 TiOF 3 mesocrystals could thus serve as a crystallographically matched template for the subsequent formation of TiO 2 mesocrystals ( Figure 2). Owing to the great effectiveness of the methodology, NH 4 TiOF 3 mesocrystals with a variety of morphologies were obtained by simply adjusting the reaction parameters, giving rise to a series of morphology-preserved anatase TiO 2 mesocrystals [44,45,137,141,143]. In addition, single-crystalline NH 4 TiOF 3 crystals could also be utilized as a template for the oriented topotactic formation of anatase TiO 2 mesocrystals.…”
