Abstract

Novel sol–gel process is introduced to fabricate Al2O3/TiO2 powder Inorganic salt other than expensive alkoxide is used as precursors Core/shell structure is achieved by dropwise addition of TiO2 sol into Al2O3 sol and ultrafine raw powders are not utilized as cores in the onepot process The phase evolution microstructure surface composition and particle size changes in the core/shell structure powders are characterized Upon calcination the anatasetorutile transformation of TiO2 phase occurs at low temperature due to the oxygen vacancies of adjacent Al2O3 TEM image shows the core/shell morphology of the powder and 110 and 101 planes of Al2O3/TiO2 are detected in the interface from HRTEM image EDS and XPS spectra verify that the Al2O3 core is fully covered by a thin TiO2 layer The average particle size decreases slightly due to the volume reduction caused by the anatasetorutile and γtoα Al2O3 transformations which increase slightly at 1050 °C due to solid phase sintering of the composite powder
