摘要：

This study focuses on the synthesis of SrVO3 3 through the reduction of Sr2V2O7 2 V 2 O 7 by annealing in a reducing atmosphere. The effects of annealing temperature and annealing duration on Sr2V2O7 2 V 2 O 7 were investigated. The X-ray powder diffraction pattern showed that stoichiometric changes to Sr2V2O7 2 V 2 O 7 were achieved only at an elevated annealing temperature of 1000 degrees C in a reducing atmosphere, and that the desired SrVO3 3 was obtained only after 144 h of annealing. Further investigation of SrVO3 3 was performed using X-ray photoelectron spectroscopy, which confirmed that the reduction of V 5+ found in Sr2V2O7 2 V 2 O 7 to V 4+ found in SrVO3 3 was achieved.
