Abstract:
In the present work, lanthanum-doped mesostructured SrTiO3 materials (LMSTs)
were successfully prepared via self-assembly sol-gel combustion method in the presence of
non-ionic triblock copolymer (Pluronic P123) as a structure-directing agent. Citric acid was
added into the synthesis mixture to enhance the metal ions interaction, and to promote the
formation of ternary solid solution of cubic perovskite at relatively low temperatures. The
solubility limit of La3+ into the SrTiO3 lattice was examined by varying the doping amount
and calcination temperatures. Moreover, the effects of La/Sr atomic ratio on the structural
and textural properties of the resulting materials were investigated by using various
characterization techniques. The results show that the substitution of La3+ into the SrTiO3
lattice generated cubic perovskite LaxSr1-xTiO3. The addition of citric acid enhanced the
purity and crystallinity of perovskite phases. The solubility limit of La3+ substitution was
suggested to be the La/Sr ratio of 0.43 above which a La-rich amorphous phase segregated on
the material surface. However, the mesoporosity and specific surface area of the materials
were increased with the La doping amount
