Titanium oxide nanotubes with high SSA>300m2/g.
Feature: Products with different PH values can be prepared according to different post-treatment processes.
Application: Environment field and energy field.
Nanostructures of titanium dioxide in the unique properties of optics, biology, electricity, etc, and become one of the hot spot of current research, and widely application of light catalysis, photovoltaic cells, sensors and coatings, etc., especially for tubular nanometer titanium dioxide, because with controllable size and the characteristics of highly ordered, more and more attention.
Compared with one-dimensional nanostructures such as nanorods and nanowires, titanium dioxide nanotubes have a larger specific surface area, which can provide more active centers, so that titanium dioxide nanotubes have better performance in photocatalysis, photocell and other aspects.
The application of TiO2 titanium oxide nanotubes is mainly in the field of environment and energy.
1. Environmental field: photocatalytic degradation of pollutants and gas sensor
Titanium dioxide is one of the most widely used photocatalysts for degrading organic pollutants in the field of water treatment.
The researchers used TIO2 nanotubes produced by hongwu nanometer to degrade bisphenol A (BPA). The results showed that the degradation rate of BPA reached 80.1% after adding TIO2 nanotubes as catalyst, 51.1% higher than that when adding TIO2 nanoparticles, indicating that TIO2 nanotubes had good photocatalytic performance.
TIO2 nanotube is used in sensor materials to detect oxygen, carbon monoxide, hydrogen, etc. It has been proved that TIO2 nanotube is highly sensitive to carbon monoxide, hydrogen, ammonia and other gases.This high gas sensitivity activity is due to the special morphology and structure of TIO2 nanotubes and the high symmetry of nano size.
2. Energy field: photocatalytic decomposition of water to produce hydrogen and dye-sensitized solar cells.
Photocatalytic decomposition of water into hydrogen has been a new area of research since researchers discovered that TiO2 can be made from water by irradiated with ultraviolet light.
In order to effectively utilize visible light, TiO2 nanotubes are considered to be combined with organic semiconductor (dye) that can effectively absorb visible light, so as to realize the effective utilization of visible light.
