Abstract	In this work, we investigate the formation of nanobubbles on a surface coated with TiO(2) in an aqueous solution by in situ tapping-mode atomic force microscopy (TMAFM). The TiO(2)-coated surface can generate hydrogen through photocatalytic reaction in methanol/water solution when ultraviolet (UV) light (wavelength lambda < 400 nm) is illuminated on the surface. We found that nanobubbles could be produced and existed at the TiO(2)/water interface during the TiO(2) photocatalytic process. By employing a combination of techniques, including phase imaging and contact-mode imaging, we could confirm the gas origin of such observed nanobubbles. In addition, the evolution process of nanobubbles at the TiO(2)/water interface has also been monitored with time of the photocatalytic reaction.
