May 15, 2016 · The TiO 2 NRAs sensors prepared at 140 °C for 3 h exhibited better response properties to O 2 at room temperature with a fast response and recovery time. The research indicates that the TiO 2 NRAs prepared by the simple AVO process is a good choice for detecting O 2 at room temperature.

Jan 28, 2011 · Stacks of multilayered rutile TiO(2) nanoflowers can grow on a titanium film through a simple acid vapour oxidation (AVO) method. The growth of this interesting hierarchical architecture is due to the formation of rutile {101} twinned structures and a subtle mismatching between the lattice spacings …

The rutile TiO 2 NRAs prepared in a low HCL concentration vapor environment by AVO process could be widely used in kinds of applications, especially gas sensors which will be explored further in the follow work.

A general acid vapor oxidation (AVO) strategy has been developed to grow highly oriented hierarchically structured rutile TiO2 nanoarrays with tunable morphologies from titanium thin films.

Jan 20, 2025 · Experimental and theoretical analyses demonstrate that terminal hydroxyls adsorbed at unsaturated cationic sites play an essential role in boosting V O V Ti V O formation, which enhances H 2 O...

Nov 26, 2024 · In the present study, the amphoteric nature of TiO 2 in the designed CaF 2-TiO 2-MgO-SiO 2 fluxes has been fully demonstrated. The coexistence of [IV] Ti, [V] Ti, and [VI] Ti in the polymeric network has been verified via Ti2p X-ray photoelectron spectroscopy (XPS).

Dec 15, 2015 · AgI–FG–TiO 2 nanocomposites were synthesized via facile, fast, and scalable microwave irradiation method. GO were functionalized through novel approach using CVD. AgI–FG–TiO 2 nanocomposites displayed markedly enhanced photocatalytic activities toward the decomposition of organic dye.

Dec 1, 2024 · In this present communication, a novel ternary nanocomposite, NiO/TiO 2 /rGO (NTG), was synthesised via a simple hydrothermal technique for photosupercapacitor application. The XRD pattern confirmed the crystalline nature and …

Short-term, aqueous aging of a commercial nanocomposite TiO2 UV filter with a protective SiO2 shell was examined in abiotic simulated fresh- and seawater. Under these conditions, the SiO2 layer...

In this study we introduced a novel chemical vapor deposition (CVD) approach to functionalize powder graphene oxide (GO). The functionalize graphene (FG) sheets were then used for the attachment of AgI and TiO 2 nanoparticles to form a ternary composites.
