Synthesis, Structural and Optical Characterization of Sol–Gel-Derived Y-Doped Mesoporous $ CeO_{2} $
Abstract Highly crystalline and thermally stable undoped $ CeO_{2} $ and Y-doped mesoporous $ CeO_{2} $ particles have been synthesized from cerium(III) nitrate hexahydrate [Ce($ NO_{3} $)3·$ 6H_{2} $O] by the sol–gel method. Mesoporous $ CeO_{2} $ doped with 2 mol.% $ Y_{2} %$ O_{3} $ and calcined...

| 520 | |a Abstract Highly crystalline and thermally stable undoped $ CeO_{2} $ and Y-doped mesoporous $ CeO_{2} $ particles have been synthesized from cerium(III) nitrate hexahydrate [Ce($ NO_{3} $)3·$ 6H_{2} $O] by the sol–gel method. Mesoporous $ CeO_{2} $ doped with 2 mol.% $ Y_{2} %$ O_{3} $ and calcined at 500°C possesses specific surface area of 130.39 $ m^{2} $/g and retains a surface area of 91.84 $ m^{2} $/g at 600°C. In comparison, undoped calcined materials have smaller specific surface areas of 43.23 $ m^{2} $/g and 20.24 $ m^{2} $/g at 500°C and 600°C, respectively. Results from x-ray diffraction (XRD) analysis, Raman spectroscopy, and selected-area electron diffraction (SAED) analysis indicated that the synthesized undoped $ CeO_{2} $ and Y-doped mesoporous $ CeO_{2} $ have the fluorite structure of bulk $ CeO_{2} $. The crystallite size of $ CeO_{2} $ is also considerably reduced by doping. The optical bandgap was found to be 3.24 eV for the undoped and 3.36 eV for the doped samples with calcination at 600°C. These results suggest that there are potential applications of Y-doped mesoporous $ CeO_{2} $ with nanocrystals in the design of photocatalysts and optical devices. | ||

Mesoporous $ CeO_{2} $ doped with 2 mol.% $ Y_{2} %$ O_{3} $ and calcined at 500°C possesses specific surface area of 130.39 $ m^{2} $/g and retains a surface area of 91.84 $ m^{2} $/g at 600°C. In comparison, undoped calcined materials have smaller specific surface areas of 43.23 $ m^{2} $/g and 20.24 $ m^{2} $/g at 500°C and 600°C, respectively. Results from x-ray diffraction (XRD) analysis, Raman spectroscopy, and selected-area electron diffraction (SAED) analysis indicated that the synthesized undoped $ CeO_{2} $ and Y-doped mesoporous $ CeO_{2} $ have the fluorite structure of bulk $ CeO_{2} $. The crystallite size of $ CeO_{2} $ is also considerably reduced by doping. The optical bandgap was found to be 3.24 eV for the undoped and 3.36 eV for the doped samples with calcination at 600°C.

Mesoporous $ CeO_{2} $ doped with 2 mol.% $ Y_{2} %$ O_{3} $ and calcined at 500°C possesses specific surface area of 130.39 $ m^{2} $/g and retains a surface area of 91.84 $ m^{2} $/g at 600°C. In comparison, undoped calcined materials have smaller specific surface areas of 43.23 $ m^{2} $/g and 20.24 $ m^{2} $/g at 500°C and 600°C, respectively. Results from x-ray diffraction (XRD) analysis, Raman spectroscopy, and selected-area electron diffraction (SAED) analysis indicated that the synthesized undoped $ CeO_{2} $ and Y-doped mesoporous $ CeO_{2} $ have the fluorite structure of bulk $ CeO_{2} $. The crystallite size of $ CeO_{2} $ is also considerably reduced by doping. The optical bandgap was found to be 3.24 eV for the undoped and 3.36 eV for the doped samples with calcination at 600°C. These results suggest that there are potential applications of Y-doped mesoporous $ CeO_{2} $ with nanocrystals in the design of photocatalysts and optical devices.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CeO</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">yttrium</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">mesoporous</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">doping</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">sol–gel</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Kun-Dar</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lu, Cheng-Hsueh</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shen, Jung-Hsiung</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Teoh, Lay Gaik</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Chiang, Ghi Wei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of electronic materials</subfield><subfield code="d">Warrendale, Pa : TMS, 1972</subfield><subfield code="g">42(2013), 8 vom: 06.

Synthesis, Structural and Optical Characterization of Sol–Gel-Derived Y-Doped Mesoporous $ CeO_{2} $ |
| abstract |
Abstract Highly crystalline and thermally stable undoped $ CeO_{2} $ and Y-doped mesoporous $ CeO_{2} $ particles have been synthesized from cerium(III) nitrate hexahydrate [Ce($ NO_{3} $)3·$ 6H_{2} $O] by the sol–gel method. Mesoporous $ CeO_{2} $ doped with 2 mol.% $ Y_{2} %$ O_{3} $ and calcined at 500°C possesses specific surface area of 130.39 $ m^{2} $/g and retains a surface area of 91.84 $ m^{2} $/g at 600°C. In comparison, undoped calcined materials have smaller specific surface areas of 43.23 $ m^{2} $/g and 20.24 $ m^{2} $/g at 500°C and 600°C, respectively. Results from x-ray diffraction (XRD) analysis, Raman spectroscopy, and selected-area electron diffraction (SAED) analysis indicated that the synthesized undoped $ CeO_{2} $ and Y-doped mesoporous $ CeO_{2} $ have the fluorite structure of bulk $ CeO_{2} $. The crystallite size of $ CeO_{2} $ is also considerably reduced by doping. The optical bandgap was found to be 3.24 eV for the undoped and 3.36 eV for the doped samples with calcination at 600°C. These results suggest that there are potential applications of Y-doped mesoporous $ CeO_{2} $ with nanocrystals in the design of photocatalysts and optical devices. © TMS 2013 |
