Description
【０００１】
【発明の属する技術分野】
本発明は、硫黄（Ｓ）を不純物として添加したＴｉＯ2光触媒材料の作製方法に関するものである。さらに詳しくは、ＴｉＳ2を高温で焼成することによって得られるＳ添加ＴｉＯ2の作製方法に関するものである。
【０００２】
【従来の技術】
クリーンな光エネルギーを利用するＴｉＯ2光触媒材料は、空気及び水の浄化、脱臭、殺菌、抗菌などに関する技術に幅広く応用されている。一方で、光触媒反応のさらなる高効率化、また太陽光を利用できる可視光応答型光触媒材料の開発に向けた研究も盛んに行われている。ＴｉＯ2への可視光応答性の付与に関しては、金属イオン添加による電子構造改質によって実現させようという試みが大半を占めてきた。しかし、ほとんどの場合、添加された不純物イオンがキャリアの再結合中心として働くため可視域において触媒能は見られず、さらに紫外域におけるＴｉＯ2本来の光触媒能さえも低下してしまう。
【０００３】
これに対して、非金属イオンの窒素（Ｎ）やフッ素（Ｆ）を添加し、ＴｉＯ2の酸素（Ｏ）サイトに置換した場合には光触媒能が向上することが知られている。この理由としては、Ｎ添加によっては可視光応答性が付与されるためであり、またＦを添加したＴｉＯ2では紫外域における光応答性が向上するためだとされている。さらに、ＮとＦよりも大きなイオン半径を持つＳをＯと置換した場合は、ＴｉＯ2の電子構造がより大幅に改質されることが期待できるため、一層の光触媒能の向上が見込まれる。
【０００４】
また、特開２００１−２０７０８２公報においても、ＴｉＯ2へのＳ添加が、可視光で応答する光触媒材料の作製法として有効な手段であると報告されている。しかしながら、ＳとＯの置換に必要なエネルギーは非常に大きいため、ＳとＯが置換されたＴｉＯ2いわゆるＳ添加ＴｉＯ2の作製は困難であると考えられている。また、実際に当該物質の作製されたという実施例は存在しない。
【０００５】
【発明が解決しようとする課題】
本発明は、以上の事情を鑑みてなされており、従来困難とされてきたＴｉＯ2へのＳ添加を可能にするものである。本発明の課題は、Ｓ添加ＴｉＯ2とその作製法を提供することである。
【０００６】
【課題を解決するための手段】
本発明は、上記の課題を解決するものとして、ＴｉＳ2を焼成して得られる光触媒材料の作製方法を提供する。
【０００７】
上述した通り、ＴｉＯ2においてＳとＯを置換することは非常に困難であるとされている。そのためＴｉ−Ｓ結合を有するＴｉＳ2を出発物質として選択し、これを焼成して酸化することでＳ添加ＴｉＯ2を作製する。詳しくは、温度を４００℃〜８００℃として空気中において焼成する製造法をその態様としている。
【０００８】
【発明の実施の形態】
本発明に係わる光触媒材料は、上記のとおり、ＴｉＳ2粉末を焼成することによって得られるものである。粉末の焼成の方法には特に制限はなく、一般的には、電圧電源、温度コントローラが取り付けられた電気炉を用いて空気中で行われる。通常、焼成の温度は４００℃〜８００℃（好ましくは６００℃前後）、時間は２時間〜１０時間（好ましくは５時間前後）である。
【０００９】
本発明で用いるＴｉＳ2は、結晶構造としてヨウ化カドミウム構造を有しており、その形状には特に制限はないが、粉末や薄膜などが好ましい。また、ＴｉＳ2の合成法にも特別な制限はなく、赤熱したＴｉＯ2上に二硫化炭素を通じてつくる方法などが挙げられる。このような手法で合成されたＴｉＳ2は、粉末であれば高純度のものが市販されている。以下、実施例を示して、さらに詳しく本発明について説明する。
【００１０】
【実施例】
（実施例１）
ＴｉＳ2粉末（９９．９％）を空気中にて電気炉で焼成した。焼成温度は６００℃とし、焼成時間は５時間とした。また、温度コントローラによって昇温及び降温速度を５℃／分に制御した。
【００１１】
図１に示されるように、焼成して得られた試料のＸ線回折パターンは、ＴｉＯ2のアナターゼ構造に由来する回折ピークが観測され、同相の形成が確認された。即ち、図１は、ＴｉＳ2を空気中にて６００℃で５時間焼成して得た試料のＸ線回折パターンである。その下には比較のためのアナターゼＴｉＯ2のものが示されている。焼成後に得られた試料はアナターゼ構造を持つことが確認できる。
【００１２】
また、Ｘ線光電子分光測定によって、同試料にはＳが微量残留し、それがＴｉＯ2のＯと置換した構造を持つことが明らかになった。
さらに、図２に示されるように、拡散反射スペクトルにおいて、吸収帯がアナターゼＴｉＯ2と比較して低エネルギー側にシフトした。即ち、図２は、ＴｉＳ2を空気中にて６００℃で５時間焼成して得た試料の拡散反射スペクトル（濃い線）である。また比較のためのアナターゼＴｉＯ2のもの（薄い線）が示されている。焼成後の試料は純粋なアナターゼＴｉＯ2と比較して、吸収帯が低エネルギー側にシフトしていることが確認できる。
【００１３】
また、バンド計算による理論的な解析の結果と比較することによって、この吸収帯のシフトはＴｉＯ2のＯサイトヘのＳの置換に起因することが分かった。添加されたＳは価電子帯の幅を広くし、結果としてバンドギャップを減少させる効果を有するものと考えられる。
【００１４】
【発明の効果】
以上詳しく説明したとおり、本発明により、Ｓ添加ＴｉＯ2の作製が可能となる。またＳがＯサイトに置換することによってバンドギャップが減少し、元の
３．１ｅＶよりも低エネルギー側での光応答性が実現される。以上より、本発明は、可視光応答性を持つた新規光触媒材料の創製に向けて極めて有効である。

BACKGROUND OF THE INVENTION
The present invention relates to a method for producing a TiO 2 photocatalytic material to which sulfur (S) is added as an impurity. More specifically, the present invention relates to a method for producing S-added TiO 2 obtained by firing TiS 2 at a high temperature.
[0002]
[Prior art]
A TiO 2 photocatalyst material that utilizes clean light energy has been widely applied to technologies related to purification, deodorization, sterilization, antibacterial, and the like of air and water. On the other hand, research is being actively conducted to further increase the efficiency of photocatalytic reactions and to develop visible light-responsive photocatalytic materials that can utilize sunlight. With regard to imparting visible light responsiveness to TiO 2 , most attempts have been made to achieve it by modifying the electronic structure by adding metal ions. However, in most cases, the added impurity ions serve as carrier recombination centers, so that no catalytic ability is observed in the visible region, and even the intrinsic photocatalytic ability of TiO 2 in the ultraviolet region is reduced.
[0003]
On the other hand, it is known that the photocatalytic ability is improved when nitrogen (N) or fluorine (F) of nonmetallic ions is added and substituted with oxygen (O) sites of TiO 2 . The reason for this is that visible light responsiveness is imparted by adding N, and that TiO 2 to which F is added improves the photoresponsiveness in the ultraviolet region. Further, when S having an ionic radius larger than that of N and F is replaced with O, the electronic structure of TiO 2 can be expected to be significantly modified, so that further improvement in photocatalytic activity is expected.
[0004]
Japanese Patent Laid-Open No. 2001-207082 also reports that addition of S to TiO 2 is an effective means for producing a photocatalytic material that responds with visible light. However, since the energy required for substitution of S and O is very large, it is considered difficult to produce TiO 2 in which S and O are substituted, so-called S-added TiO 2 . In addition, there is no example that the substance is actually produced.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and makes it possible to add S to TiO 2 , which has been considered difficult in the past. An object of the present invention is to provide S-added TiO 2 and a method for producing the same.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a method for producing a photocatalytic material obtained by firing TiS 2 .
[0007]
As described above, it is considered extremely difficult to replace S and O in TiO 2 . Therefore, TiS 2 having a Ti—S bond is selected as a starting material, and this is fired and oxidized to produce S-added TiO 2 . Specifically, the embodiment is a production method in which the temperature is set to 400 ° C. to 800 ° C. and firing in the air.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The photocatalytic material according to the present invention is obtained by firing TiS 2 powder as described above. There is no particular limitation on the method for firing the powder, and the powder is generally performed in the air using an electric furnace equipped with a voltage power source and a temperature controller. Usually, the firing temperature is 400 ° C. to 800 ° C. (preferably around 600 ° C.), and the time is 2 hours to 10 hours (preferably around 5 hours).
[0009]
TiS 2 used in the present invention has a cadmium iodide structure as a crystal structure, and the shape is not particularly limited, but a powder or a thin film is preferable. Also, rather than also particular restriction on the synthesis method of TiS 2, a method for making through carbon disulfide and the like on the TiO 2 it was red hot. TiS 2 synthesized by such a technique is commercially available in high purity if it is powder. Hereinafter, the present invention will be described in more detail with reference to examples.
[0010]
【Example】
Example 1
TiS 2 powder (99.9%) was fired in air in an electric furnace. The firing temperature was 600 ° C. and the firing time was 5 hours. Further, the temperature increase / decrease rate was controlled to 5 ° C./min by a temperature controller.
[0011]
As shown in FIG. 1, in the X-ray diffraction pattern of the sample obtained by firing, a diffraction peak derived from the anatase structure of TiO 2 was observed, confirming the formation of the same phase. That is, FIG. 1 is an X-ray diffraction pattern of a sample obtained by firing TiS 2 in air at 600 ° C. for 5 hours. Below that for anatase TiO 2 for comparison. It can be confirmed that the sample obtained after firing has an anatase structure.
[0012]
Also, X-ray photoelectron spectroscopic measurement revealed that a small amount of S remained in the sample, which had a structure substituted with O of TiO 2 .
Furthermore, as shown in FIG. 2, in the diffuse reflection spectrum, the absorption band shifted to a lower energy side as compared with anatase TiO 2 . That is, FIG. 2 is a diffuse reflection spectrum (dark line) of a sample obtained by baking TiS 2 in air at 600 ° C. for 5 hours. In addition, the anatase TiO 2 (thin line) is shown for comparison. It can be confirmed that the sample after firing has an absorption band shifted to a lower energy side as compared with pure anatase TiO 2 .
[0013]
Further, by comparing with the result of theoretical analysis by band calculation, it was found that this absorption band shift was caused by substitution of S into O site of TiO 2 . The added S is considered to have the effect of widening the valence band and consequently reducing the band gap.
[0014]
【The invention's effect】
As described above in detail, the present invention makes it possible to produce S-added TiO 2 . Further, when S is replaced with an O site, the band gap is reduced, and photoresponsiveness on the lower energy side than the original 3.1 eV is realized. As described above, the present invention is extremely effective for creating a novel photocatalytic material having visible light responsiveness.

FIG. 2 is a diffuse reflectance spectrum (dark line) of a sample obtained by baking TiS 2 in air at 600 ° C. for 5 hours, and that of anatase TiO 2 for comparison (thin line). Is also shown.
