Nanocrystalline anatase derived from modified alkoxide mesostructured gel
Abstract A sol prepared by chelation of titanium n-butoxide with ethyl acetoacetate (1:1) was slowly hydrolyzed, and the obtained gel was thermally treated in order to produce anatase. Samples were investigated by means of FTIR, XRD, DTA/TG, $ N_{2} $ adsorption–desorption isotherms, FESEM and HRTEM...

| 520 | |a Abstract A sol prepared by chelation of titanium n-butoxide with ethyl acetoacetate (1:1) was slowly hydrolyzed, and the obtained gel was thermally treated in order to produce anatase. Samples were investigated by means of FTIR, XRD, DTA/TG, $ N_{2} $ adsorption–desorption isotherms, FESEM and HRTEM. It was determined the modified alkoxide is partially hydrolyzed, leaving small amount of butoxide and ethyl acetoacetate groups attached to titanium. XRD pattern and HRTEM micrograph revealed gel ordering at the mesostructure scale. Observed mesostructure was found to be consisted with inorganic–organic nanoclusters, exhibiting some polydispersity in the size and variations in composition. Thermal decomposition exhibits evaporation of water and butanol, elimination of ethyl acetoacetate and butoxy groups, carbonate removal, anatase crystallization and transformation to rutile, accompanied with oxidation of carbonaceous species. After 2 h at 350 °C pure nanocrystalline anatase crystallites were obtained having average crystallite size of 16.4 nm with majority of exposed {101} facets. | ||

Samples were investigated by means of FTIR, XRD, DTA/TG, $ N_{2} $ adsorption–desorption isotherms, FESEM and HRTEM. It was determined the modified alkoxide is partially hydrolyzed, leaving small amount of butoxide and ethyl acetoacetate groups attached to titanium. XRD pattern and HRTEM micrograph revealed gel ordering at the mesostructure scale. Observed mesostructure was found to be consisted with inorganic–organic nanoclusters, exhibiting some polydispersity in the size and variations in composition. Thermal decomposition exhibits evaporation of water and butanol, elimination of ethyl acetoacetate and butoxy groups, carbonate removal, anatase crystallization and transformation to rutile, accompanied with oxidation of carbonaceous species. After 2 h at 350 °C pure nanocrystalline anatase crystallites were obtained having average crystallite size of 16.4 nm with majority of exposed {101} facets.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Anatase</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Chelating agent</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hybrid nanoclusters</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mesoporous gel</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Nanocrystals</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Minga, I.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mandić, V.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Matijašić, G.</subfield><subfield code="e">verfasserin</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 thermal analysis and calorimetry</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V., 1969</subfield><subfield code="g">124(2015), 2 vom: 14.

Nanocrystalline anatase derived from modified alkoxide mesostructured gel |
| abstract |
Abstract A sol prepared by chelation of titanium n-butoxide with ethyl acetoacetate (1:1) was slowly hydrolyzed, and the obtained gel was thermally treated in order to produce anatase. Samples were investigated by means of FTIR, XRD, DTA/TG, $ N_{2} $ adsorption–desorption isotherms, FESEM and HRTEM. It was determined the modified alkoxide is partially hydrolyzed, leaving small amount of butoxide and ethyl acetoacetate groups attached to titanium. XRD pattern and HRTEM micrograph revealed gel ordering at the mesostructure scale. Observed mesostructure was found to be consisted with inorganic–organic nanoclusters, exhibiting some polydispersity in the size and variations in composition. Thermal decomposition exhibits evaporation of water and butanol, elimination of ethyl acetoacetate and butoxy groups, carbonate removal, anatase crystallization and transformation to rutile, accompanied with oxidation of carbonaceous species. After 2 h at 350 °C pure nanocrystalline anatase crystallites were obtained having average crystallite size of 16.4 nm with majority of exposed {101} facets. |
