•Ti0.95Er0.05O2 nanocrystal was synthesized by hydrothermal method.•Ti0.95Er0.05O2 nanocrystal is very pure.•Ti0.95Er0.05O2 showed high photocatalytic activity with irradiation of UV light.
The preparation of Ti0.95Er0.05O2 nanocrystal by a facile surfactant-free hydrothermal method was reported in this work. The obtained materials were investigated by means of HRTEM, SEM, EDS, XPS and XRD. The results indicated that Ti1 − xErxO2 were obtained in uniform nanometer scale and very pure. According to the photocatalytic activity for the photocatalytic degradation of methylene blue, Ti0.95Er0.05O2 is nearly twice higher than that of the undoped sample. Furthermore, photoelectrochemical investigation has been carried out. The photocurrent intensity of Ti0.95Er0.05O2 is nearly twice higher than that of the undoped TiO2, which is in well accordance with their photocatalytic performance.
