Abstract:

With unique electronic effect, TiO2 nanoparticles can be used as photocatalysts to reduce or eliminate the organic pollutants only under irradiation of sunlight. It is, therefore, highly desirable to improve its dispersion and solubility to broaden its application in different fields especially in environmental conservation. Here provides a case of two-step method to prepare yellow transparent water-soluble TiO2-ionic liquids hybrid nanomaterial. In this hybrid system, organic sulfonate groups as canopy provide “self-solvent” for the dispersion of the TiO2 nanoparticles. This dispersion experiment results indicated that the water-soluble organic canopy in the TiO2-ionic liquids hybrid nanomaterial offered good solubility in water and the TiO2-ionic liquids hybrid nanomaterials used in-home decoration could be easily wiped away on the surface of furniture. Data from photocatalytic degradation efficiency for decomposing formaldehyde demonstrated that the hybrid nanofluids possessed excellent photocatalytic performance. The water-soluble TiO2-ionic liquids hybrid nanomaterials could be a promising candidate for environmental conservation in the future.

Key words: TiO2-ionic liquids, hybrid nanomaterials, water-soluble, photocatalytic
