Synthesis and characterization of single-crystal PbTiO3 nanorods

Preparation and characterization of SiO2-pillared H2Ti4O9 and its photocatalytic activity for methylene blue degradation

“…The Raman bands at 395, 458, 679 and 869 cm −1 were characteristic of typical protonated titanate [25] and the peak at 264 cm −1 was assigned to Ti-OH bonds [26]. SiO 2 pillaring led to the weakening of Raman intensity and slight shift of Raman peaks, possibly resulting from the changes in morphology and particle size during the pillaring process [27,28].…”

Preparation of single-crystal PbTiO3 nanorods by phase transformation from Pb2Ti2O6 nanorods

“…Various techniques have been applied to prepare lead titanate powders, such as sol-gel method [4,5], oxidant-peroxo process [6], coprecipitation [7] and hydrothermal method [8][9][10], besides the traditional solid-state reaction of mixed oxides [11]. One-dimensional PbTiO 3 crystallites, such as nanowires, nanorods, nanotubes, nanostrips and fibers have been successfully prepared by sol-gel template and molten salt method [12][13][14][15][16][17][18]. In addition, PbTiO 3 nanowires, nanorods and nanotubes have been synthesized by microwave-hydrothermal, * Corresponding author.…”

Quantum confinement of lead titanate nanocrystals by wet chemical method

“…For example, Urban and co-workers have fabricated well-isolated nanowires of BaTiO 3 and SrTiO 3 with diameters ranging from 10 to 50 nm and lengths reaching up to 10 µm by solution-phase decomposition of bimetallic alkoxide precursors in the presence of coordinating ligands [16]. Deng et al have fabricated single crystalline PbTiO 3 nanorods (NRs) with diameters of 50 nm to 80 nm by solid-state reaction [17]. Hydrothermal technique is a promising way for fabricating ferroelectric nanomaterials because it can realize a low processing temperature of 200 °C or less, and can obtain products with high purity [18].…”
