Sodium titanate nanorods: Preparation, microstructure characterization and photocatalytic activity

Structural characterization of single crystals of sodium titanate nanowires prepared by hydrothermal process

“…The output is shown in Fig. 3e, indicating that the wire grew along the (0 1 0) direction of Na 2 Ti 6 O 13 , with an interplanar spacing of about 0.74 nm, a value consistent with reports found elsewhere [10,13,14,23]. The wire in Fig.…”

“…Xu et al [9] synthesized sodium hexatitanate nanowires from a mixture of BaC 2 O 4 , TiO 2 (anatase) and NaCl with a molar ratio of 1:1:20. The mixture was ground with 5 mL of polyglycol ether and was annealed in a furnace at 850 1C for 3 h. Stengl et al [10] synthesized sodium titanate nanorods through the reaction of commercial nanostructured sodium titanate with ethylene glycol and subsequent heating at 500 and 900 1C. Although is not a titanate, it is worth mentioning that Du et al [11] synthesized helical potassium hexaniobate nanotubes using a stoichiometric mixture of Nb 2 O 5 and K 2 CO 3 in an alumina crucible with subsequent heating at 1050 1C.…”

Synthesis, conversion, and comparison of the photocatalytic and electrochemical properties of Na2Ti6O13 and Li2Ti6O13 nanobelts

“…The lattice spacings are 0.36 and 0.50 nm, respectively, which cor- (1 1 0) and (3 0 0) is 76°, which is in good consistent with the calculated interfacial angle of 75.8°. On the basis of analyzing SAED and HRTEM pattern, the growth direction of the Na 2 Ti 6 O 13 nanobelt is determined to its [0 1 0] crystallographic orientation, which agrees with previous reports [5,6].…”

“…In particular, 1D alkali-metal hexatitanates (A 2 Ti 6 O 13 , A is alkali-metal) with a tunnel structure have given rise to extraordinary attention as photocatalysts because they have a large specific surface area and structural anisotropy [1,2]. For example, Na 2 Ti 6 O 13 whiskers exhibited good photocatalytic activity by the photodecolorization of methyl orange under ultraviolet light (UV) irradiation [3,4]; Na 2 Ti 6 O 13 nanorods and nanobelts also presented good photocatalytic activity for the decomposition of 4-chlorophenol and Rhodamine B (RhB) under UV irradiation, respectively [5][6][7]. As compared with Na 2 Ti 6 O 13 polycrystallines, 1D Na 2-Ti 6 O 13 nanostructures have many advantages as photocatalysts.…”

Alginate-Polymer-Caged, C18-Functionalized Magnetic Titanate Nanotubes for Fast and Efficient Extraction of Phthalate Esters from Water Samples with Complex Matrix

“…The effects of salt addition to water containing organic pollutants prior their extraction has been studies as a favoring factor because, in theory, high ionic strength improves extraction of organic compounds (24). In this study, 0-400 mM NaCl were added to the solution to examine the impact of ionic strength on the recoveries of target compounds.…”
