Abstract

In this work, we investigated the effects of GO on dispersion stability of the two types of TiO2 NPs under different pHs. At pH 4, heteroaggregation may occur between GO and the two types of TiO2 NPs (TiO2 Nanotube and TiO2 Nanowire), enhancing the sedimentation of TiO2 NPs. However, at pH 7 and 10, GO enhanced the suspension of the two types of TiO2 NPs. Electrostatic interaction could be a major mechanism for TiO2 NPs-GO interaction.
