Abstract: In this study, calcium carbonate, sepiolite, and commonly used diatomite (DE) carriers were mixed to prepare calcium carbonate or sepiolite mixed DE/nano-titanium dioxide (TiO <subscript>2</subscript> ). The analyses of X-ray diffraction and scanning electron microscope confirmed that the particle size of nano-TiO <subscript>2</subscript> was about 20-24 nm in DE/nano-TiO <subscript>2</subscript> , and the particles were relatively uniform. When (calcium carbonate and sepiolite + DE)/nano-TiO <subscript>2</subscript> was used, the Ti content in the composite remained unchanged, while the particle size of nano-TiO <subscript>2</subscript> increased to a certain extent. Among them, the use of (calcium carbonate + DE)/nano-TiO <subscript>2</subscript> increased the Ti content in the composite material significantly. Therefore, the findings demonstrated the feasibility of nano-TiO <subscript>2</subscript> supported by the mixed carrier.<br /> (© 2022. The Author(s).)
