Abstract
TiO2-based composites doped with d-metal oxides are prospective catalysts. In this paper we obtained spherical particles of TiO2–NiO and TiO2–Co3O4 composites by a template method accompanied with sol-gel one. Ion exchange resin of TOKEM-100 and TOKEM-250 was used as an organic polymer matrix. Complex studies were carried out to identify the formation process, compositions and morphology of obtained particles by thermal analysis, X-ray diffractometey, scanning electron microscopy and micro-X-ray spectral analyses The formation of TiO2–Co3O4 and TiO2–NiO composite particles ends at 600 and 500°C, respectively at using TOKEM-100 and TOKEM-250 resins. The size of final spherical particles found to be in a range from 300 to 700 μm, and their morphology depends on its composition.
