摘要

Lanthanide tantalite LnTaO_4 (Ln= La, Nd, Sm, Dy, Er and Tm) was synthesized by a solid state reaction between mixed powders of Ln_2O_3 (Ln=La, Nd, Sm, Dy, Er and Tm) and Ta_2O_5. The single-phase LnTaO_4 was prepared by sintering at temperatures of 1423-1673 K in air. The SEM observation showed that the particles were provided with the growth steps and the depeloped facets. The photocatalytic activity for water splitting of LnTaO_4 prepared was measured under UV light irradiation. The activity obtained was higher than that previously reported. These results suggested the crystallinity of LnTaO_4 photocatalysts correlates closely with the efficiency of water splitting.
