Facile synthesis of low cost anatase titania nanotubes and its electrochemical performance

Easy Room Temperature Synthesis of High Surface Area Anatase Nanowires with Different Morphologies

“…By further increasing the OH − concentration to the range of 1 mol/l to 5 mol/l, the morphology directing properties of sodium hydroxide on nanowire formation are increased and the hedgehog spikes get elongated, the density of nanowires per particle is reduced and the separate particles start to get interlinked (Figure c). At a hydroxide concentration of 6.4 mol/l, the morphology is changed into a net‐like structure (Figure d), resembling nanowires grown under hydrothermal conditions with sodium hydroxide as the sole morphology directing agent . At a hydroxide concentration of 10 mol/l, the morphological evolution of the nanowires is hindered and particles composed of very short nanowires evolve as shown in Figure e).…”

“…At a hydroxide concentration of 6.4 mol/l, the morphology is changed into a net-like structure (Figure 2 d), resembling nanowires grown under hydrothermal conditions with sodium hydroxide as the sole morphology directing agent. [14] At a hydroxide concentration of 10 mol/l, the morphological evolution of the nanowires is hindered and particles composed of very short nanowires evolve as shown in Figure 2 e). Finally, when reaching an OH À concentration of 14 mol/l, no nanowire formation can be observed and assemblies of agglomerated nanoparticles shown in Figure 2 f) are produced.…”

“…Another hydrothermal approach to produce TiO 2 nanostructures is the use of sodium hydroxide to dissolve and recrystallize solid titanium oxide powder into titanate and anatase nanotubes under hydrothermal conditions, whereby anatase is obtained after suitable annealing in air. This illustrates the morphology directing properties of sodium hydroxide . Since this reaction involves the dissolution of TiO 2 , the concentration of sodium hydroxide and high temperatures are crucial for the reaction.…”

“…This illustrates the morphology directing properties of sodium hydroxide. [7,13,14] Since this reaction involves the dissolution of TiO 2 , the concentration of sodium hydroxide and high temperatures are crucial for the reaction. If instead typical titanium precursors are used in even mildly basic media, instant hydrolysis sets in which prevents the use of milder synthesis conditions.…”

Novel strategy for molybdenum disulfide nanosheets grown on titanate nanotubes for enhancing the flame retardancy and smoke suppression of epoxy resin

“…These characteristic peaks conformed to the standard diffractogram of H 2 Ti 2 O 5 ·H 2 O and showed the crystal structures of the TNTs after the disposal of the hydrothermal methods. However, the diffraction peaks of the heat‐treated TNTs pattern appeared around 2θs of 25.2, 37.8, 48.0, 53.8, 55.0, 62.7, and 68.7°; these corresponded to the (101), (004), (200), (105), (211), (204), and (116) characteristic peaks of anatase TiO 2 , respectively . In the XRD pattern of the MoS 2 –TNT hybrid, the characteristic peaks of MoS 2 and heat‐treated TNTs were observed; this indicated that the MoS 2 –TNT hybrid was synthesized.…”
