چکیده

A novel and rapid and continuous hydrothermal route to the synthesis of extensive ultra-thin 2D sodium titanate (Na(2)Ti(3)O(7)) nano-sheets using a superheated water flow at 450 degrees C and 24.1 MPa as a crystallizing medium is described. High resolution electron microscopy of the sheets revealed that they were a few layers thick and largely uncurled, highly crystalline despite their very short time under hydrothermal flow conditions. The sodium titanate sheets possessed excellent photocatalytic activity for decolourisation of methylene blue dye.

Synthesis of High Surface Area Titania Based Nanoparticles and the Effect of Surfactants

In this study, TiO2 based nanotubes and nanosheets were synthesized to be used as an adsorbent and support in various processes. As a starting material, sol-gel synthesized anatase and commercial anatase were used. TiO2 was converted to high surface area hydrogen titanate (H2Ti3O7) and sodium titanate (Na2Ti3O7) nanotubes and nanosheets under alkaline conditions with hydrothermal treatment. In ...

Charge separation in layered titanate nanostructures: effect of ion exchange induced morphology transformation.

Morphology changes induced by surface chemistry can provide important insights into photoexcitation processes on solids which are critical to photovoltaic and photocatalytic applications. This area is of particular relevance for TiO2based nanomaterials, which have become available as sheets, wires, tubes, and rods only recently. We investigated charge-separation processes on Na2Ti3O7 nanowires ...

Fabrication of PGS/CaTiO3 Nano-Composite for Biomedical Application

Biodegradable elastomeric materials are gaining extensive attention in the field of soft tissue engineering. Poly (glycerol sebacate) (PGS) is a novel biocompatible elastomer in this scope. However this polymer has poor mechanical properties especially when the molar ratio of glycerol is higher than sebacic acid. Calcium Titanate (CaTiO3) is a biocompatible ceramic with some degr...
