An ultrahigh-sensitivity and selective sensing material for ethanol: α-/γ-$ Fe_{2} %$ O_{3} $ mixed-phase mesoporous nanofibers
Abstract A process for synthesizing $ Fe_{2} %$ O_{3} $ based on electrospinning and the hard-template method was proposed such that the crystal phase of $ Fe_{2} %$ O_{3} $ could be tailored with precision. Mesoporous γ-$ Fe_{2} %$ O_{3} $, α-/γ-$ Fe_{2} %$ O_{3} $, and α-$ Fe_{2} %$ O_{3} $ nanofi...

| 520 | |a Abstract A process for synthesizing $ Fe_{2} %$ O_{3} $ based on electrospinning and the hard-template method was proposed such that the crystal phase of $ Fe_{2} %$ O_{3} $ could be tailored with precision. Mesoporous γ-$ Fe_{2} %$ O_{3} $, α-/γ-$ Fe_{2} %$ O_{3} $, and α-$ Fe_{2} %$ O_{3} $ nanofibers could be fabricated successfully by changing the synthesis parameters. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction analyses, Raman spectroscopy, and nitrogen adsorption–desorption analyses were used to characterize the structures of the synthesized products. The optimal calcination conditions for preparing α-/γ-$ Fe_{2} %$ O_{3} $ nanofibers with the highest ethanol response were determined through ethanol-sensing measurements. The mixed-phase material exhibited a significantly higher sensitivity than the corresponding purephase ones. The superior ethanol-sensing performance of the α-/γ-$ Fe_{2} %$ O_{3} $ nanofibers suggested that they may be suitable for use in alcohol sensing. Hence, a novel strategy for improving the sensing performance of metal oxide semiconductors is to assemble the different crystalline forms of the same metal oxide in one structure. Finally, the mechanism responsible for the sensing performance of α-/γ-$ Fe_{2} %$ O_{3} $ being higher than those of γ-$ Fe_{2} %$ O_{3} $ and α-$ Fe_{2} %$ O_{3} $ was elucidated on the basis of data from X-ray photoelectron spectroscopy and resistance measurements. | ||

Mesoporous γ-$ Fe_{2} %$ O_{3} $, α-/γ-$ Fe_{2} %$ O_{3} $, and α-$ Fe_{2} %$ O_{3} $ nanofibers could be fabricated successfully by changing the synthesis parameters. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction analyses, Raman spectroscopy, and nitrogen adsorption–desorption analyses were used to characterize the structures of the synthesized products. The optimal calcination conditions for preparing α-/γ-$ Fe_{2} %$ O_{3} $ nanofibers with the highest ethanol response were determined through ethanol-sensing measurements. The mixed-phase material exhibited a significantly higher sensitivity than the corresponding purephase ones. The superior ethanol-sensing performance of the α-/γ-$ Fe_{2} %$ O_{3} $ nanofibers suggested that they may be suitable for use in alcohol sensing. Hence, a novel strategy for improving the sensing performance of metal oxide semiconductors is to assemble the different crystalline forms of the same metal oxide in one structure. Finally, the mechanism responsible for the sensing performance of α-/γ-$ Fe_{2} %$ O_{3} $ being higher than those of γ-$ Fe_{2} %$ O_{3} $ and α-$ Fe_{2} %$ O_{3} $ was elucidated on the basis of data from X-ray photoelectron spectroscopy and resistance measurements.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">sensitivity enhancement</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">mixed-phase structure</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">oxygen vacancies</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">one-dimensional Fe</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">O</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ethanol sensing</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zan, Guangtao</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wu, Qingsheng</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Nano research</subfield><subfield code="d">[S.l.] : Tsinghua Press, 2008</subfield><subfield code="g">8(2015), 11 vom: 20.

An ultrahigh-sensitivity and selective sensing material for ethanol: α-/γ-$ Fe_{2} %$ O_{3} $ mixed-phase mesoporous nanofibers |
| abstract |
Abstract A process for synthesizing $ Fe_{2} %$ O_{3} $ based on electrospinning and the hard-template method was proposed such that the crystal phase of $ Fe_{2} %$ O_{3} $ could be tailored with precision. Mesoporous γ-$ Fe_{2} %$ O_{3} $, α-/γ-$ Fe_{2} %$ O_{3} $, and α-$ Fe_{2} %$ O_{3} $ nanofibers could be fabricated successfully by changing the synthesis parameters. Scanning electron microscopy, transmission electron microscopy, X-ray diffraction analyses, Raman spectroscopy, and nitrogen adsorption–desorption analyses were used to characterize the structures of the synthesized products. The optimal calcination conditions for preparing α-/γ-$ Fe_{2} %$ O_{3} $ nanofibers with the highest ethanol response were determined through ethanol-sensing measurements. The mixed-phase material exhibited a significantly higher sensitivity than the corresponding purephase ones. The superior ethanol-sensing performance of the α-/γ-$ Fe_{2} %$ O_{3} $ nanofibers suggested that they may be suitable for use in alcohol sensing. Hence, a novel strategy for improving the sensing performance of metal oxide semiconductors is to assemble the different crystalline forms of the same metal oxide in one structure. Finally, the mechanism responsible for the sensing performance of α-/γ-$ Fe_{2} %$ O_{3} $ being higher than those of γ-$ Fe_{2} %$ O_{3} $ and α-$ Fe_{2} %$ O_{3} $ was elucidated on the basis of data from X-ray photoelectron spectroscopy and resistance measurements. © Tsinghua University Press and Springer-Verlag Berlin Heidelberg 2015 |
