Abstract
The invention relates to a method for stabilizing and enhancing the activity of TiO2 through a one-step reaction. The obtained material can efficiently degrade an organic pollutant, namely, methyl orange, in visible light. The method comprises the following steps: after o-phenanthroline and tetrabutyl titanate are dissolved in ethyl alcohol and are mixed uniformly, transferring the mixture into a hydrothermal reactor for reacting; after the reaction is completed, separating and washing a sample to obtain a product. The method is characterized in that the obtained product has higher stability and more effective visible-light catalytic activity compared with that of TiO2.
Description
Technical field
The present invention relates to nanometer semiconductor oxidation field of material technology, particularly relate to a kind of stable by single step reaction and strengthen TiO2The method of activity.
Background technology
Titanium dioxide (TiO2) it is a kind of stable in physicochemical property, safety non-toxic, conductor oxidate with low cost, form Strong oxdiative atmosphere under light illumination, almost all of organic poison matter exhaustive oxidation can be resolved into the nontoxic small-molecule substances such as carbon dioxide, water. Solar energy is to clean and the energy of economy, TiO2The performance that solar energy carries out catalysis can be utilized to make its application in degraded environmental pollution field receive great concern. But TiO2Band gap wider, for 3.2eV, this makes it to absorb and accounts for the ultraviolet light (�� < 387nm) reaching ground solar energy less than 5%, can not effectively utilizing the energy of the visible ray accounting for big absolutely number in sunlight, the utilization rate of energy solar energy is extremely low. Therefore, inquire into TiO2Modified, widening its absorbance spectrum and move to visible ray, thus improving the utilization rate to solar energy, being current TiO2The focus of photocatalyst research.
A large amount of research experiments show, by adulterating [J.Phys.Chem.C, 2007,129,4538], noble metal loading [J.Phys.Chem.C, 2010,114,16475], dye sensitization [J.Photochem.Photobiol., A, 2009,204,168] etc. method can effectively widen TiO2Photoresponse scope, improve its photocatalytic activity. Nearest research shows, with the polymer containing big pi-conjugated key and TiO2Form complex, it may be possible to strengthen its photocatalytic activity. Its principle is probably the conjugated system of big �� key and is conducive to the conduction of electronics, thus be beneficial to light induced electron generation and with the separating of photohole. But the research of this respect is also very limited at present.
In the methods of the invention, it is provided that the big �� key monomeric compound of utilization of a kind of novelty modifies TiO2, strengthen its photoactive method. Utilize the adjacent luxuriant and rich with fragrance quinoline containing three big pi-conjugated keys of aromatic rings, by a simple step hydrothermal synthesis method, modify TiO2, obtain TiO2-adjacent luxuriant and rich with fragrance quinoline complex. Synergism by adjacent luxuriant and rich with fragrance quinoline so that products obtained therefrom has better heat stability and higher visible light catalysis activity.
The present invention relates to a kind of stable by single step reaction and strengthen TiO2The method of activity, raw material is easy to get, and cost is low, simple to operate, and described method has no report.
Summary of the invention
It is an object of the invention to provide a kind of stable by single step reaction and strengthen TiO2The method of activity, the present invention takes following means:
(1) adjacent luxuriant and rich with fragrance quinoline is dissolved in the ethanol of 20mL with 3mL tetrabutyl titanate, ranging for of adjacent luxuriant and rich with fragrance quinoline amount: 0.3-1.5mmol;
(2) (1) gained solution is added to hydrothermal reaction kettle, after 180 DEG C of reaction 24h, after gained solid centrifugation, cleaning, drying, namely obtain product.
The material of gained modifies TiO for utilizing adjacent luxuriant and rich with fragrance quinoline2, and be complete modification by a step hydro-thermal reaction.
The material of gained has than the better heat stability of TiO2 and visible light catalysis activity, methyl orange of can degrading under visible light.
The invention have the advantage that the monomeric organic compound neighbour's phenanthrene quinoline utilized containing big pi-conjugated key modifies TiO2, by cooperative effect, strengthen TiO2Stability and photocatalytic activity; Raw material is easy to get, and cost is low, simple to operate; Products obtained therefrom has excellent photocatalysis performance, available Visible Light Induced Photocatalytic organic pollution methyl orange.
