Water-soluble anatase TiO2 nanocrystals (NCs) were synthesized by a simple sol–gel method. The reaction time is greatly reduced even under mild conditions. High-resolution transition electron microscopy (HRTEM), X-ray diffraction (XRD) and UV–vis were used to characterize the synthesized NCs and proved that the NCs are anatase phase and about 2 nm with near spherical shape. Surface photovoltage spectroscopy (SPS) experiments show that the synthesized anatase NCs have good photovoltaic properties compared with that of poly(vinyl pyrrolidone) (PVP) coated NCs synthesized by the similar method.
Graphical abstractA simple novel method was developed to synthesize water-soluble anatase TiO2 nanocrystals. Surface photovoltage spectroscopy experiments show that the synthesized nanocrystals have good photovoltaic properties compared with that of strongly bonded surfactant coated NCs synthesized under the similar conditions.Figure optionsDownload full-size imageDownload as PowerPoint slide
