Abstract

TiO ₂ samples doped by B were prepared by the calcination of TiB ₂ in the air condition and metallothermic reduction (MTR) of TiO ₂ with Mg and B ₂O ₃ which were calcined in the Ar condition. As a result, we found that we could effectively dope B atoms to TiO ₂ samples by these methods, which were characterized by X-ray photoelectron spectroscopy of the 1 s orbital for B. These samples also show the photocatalytic activity for the oxidation of 2-propanol under the visible-light irradiation.
