“…[9][10][11][12][13] Since the semiconductor nanocrystals have been found to have superior properties than their bulk counterpart, the current world-wide intense research on nanomaterials was initiated. 14,15 Various simple one-dimensional (1D) nanostructures, such as nanotubes, 16,17 nanorods/ nanowires, 18,19 and nanobelts, 20 as well as some complex highorder architectures, such as three-dimensional (3D) hierarchical dendrites, 21,22 3D porous architectures, 23,24 and mesoporous spheres, [25][26][27] have been successfully realized through a number of approaches. As one kind of eminent microwave dielectric, ferroelectric, and photocatalytic material, the synthesis of SrTiO 3 nanostructures with various morphologies has also attracted great attention.…”
