TiO2 나노분말 제조시 HCI과 NH4OH의 첨가량에 따른 반응양상과 pH의 영향

The reaction morphology was investigated depending on the amounts of HCl and NH4OH, and theeffect of pH was studied on the preparation of TiO2 nanopowders. TiO2titanium tetra-isopropoxide. Subsequently, the effect of pH on the characteristics of the prepared TiO2 nanopowderwas evaluated depending on the amounts of the catalysts such as HCl and NH4OH. The morphology and phasetransformation of TiO2 powder prepared by hydrolysis of titanium tetra-isopropoxide were strongly influencedby the presence of the catalysts. In the case of using NH4OH, the morphology of the TiO2 powder exhibitedTi(OH)4 to anatase TiO2 and the anatase to rutile was significantly influenced by the kind and amount of thecatalysts.
