One-Step Synthesis of Anatase Nanocrystalline TiO2 at a Low Temperature for High Photocatalytic Performance

In this study, the titanium dioxide is prepared at 353 K in one hour using a one-step method. The titanium dioxide prepared using this method consists of anatase clusters with sizes of approximately 5 nm. We find that it has a specific surface area of 504 m 2 /g, the average pore diameter of a stacking hole was 71 A, and the band gaps were approximately 3.25 eV. The photocatalytic activity and stability of the titanium dioxide prepared using this method on methyl orange and rhodamine B was as good as that of P25. This method may have a grander prospect for the industrial production of the photocatalyst due to its property of convenience and energy-saving.
