BiOCl/SnS 2 core-shell heterojunction is prepared by a facile and economic hydrothermal method. The obtained BiOCl/SnS 2 heterojunction displays high photocatalytic activity in the degradation of Rhodamine B (RhB). The high performance is explained by the fast separation of the photoinduced electron-hole pairs promoted by the heterojunction. The cycle life of the heterojunction is also improved compared with individual BiOCl or SnS 2 .

“…Therefore, it should be noted that the anisometric template particles play a significant role in the development and formation of texture in lead-free piezoelectric ceramics. There is a considerable literature on the research of anisotropically shaped particles to fabricate the ideal template for lead-free textured piezoelectric ceramics [21][22][23][24][25][26][27][28].…”

Further enhancement of the piezoelectric response in lead-free piezoelectric ceramics can be accomplished by inducing preferred orientation. In this paper, attempts have been made to review the progress on the fabrication of lead-free textured piezoelectric ceramics by the (reaction) templated grain growth method. The preparation (molten salt synthesis) and alignment (tape casting and extrusion molding) of anisometric template particles were introduced in detail. The texture evolution with heating was visualized by computer simulation. The review of lead-free textured piezoelectric ceramics focused on four promising systems: Na 0.5 Bi 0.5 TiO 3 -based, K 0.5 Na 0.5 NbO 3 -based, Ba(Zr 0.2 Ti 0.8 )O 3 -(Ba 0.7 Ca 0.3 )TiO 3 and KSr 2 Nb 5 O 15 . It is suggested that texturing of lead-free morphotropic phase boundary compositions will be required in order to realize viable lead-free alternatives to current lead-based materials.

“…As one of prominent ferroelectric and piezoelectric materials, perovskite-type BaTiO 3 is mainly applied in multilayer capacitors, nonvolatile memories, thermistors, transducers, and electro-optical devices, etc, due to its large dielectric 35 constants and nonlinear optical coefficients. [4][5][6] Recently, however, some titanate-based materials including BaTiO 3 were found to bear good photocatalytic activities. [7][8][9][10][11] Obviously, these are useful exploration to environmental treatment.…”

Coral-like BaTiO 3 nanostructures have been successfully synthesized via a simple hydrothermal route at 150 °C for 15 h, employing BaCl 2 , tetrabutyltitanate [(C 4 H 9 O) 4 Ti] and NaOH as original reactants without the assistance of any surfactant or template. The phase of the as-obtained BaTiO 3 was characterized by X-ray powder diffraction (XRD). Energy dispersive spectrometry (EDS), scanning 10 electron microscopy (SEM) and (high-resolution) transmission electron microscopy (TEM/HRTEM) were employed for the composition and morphology analyses of the final product. Some factors influencing the formation of coral-like BaTiO 3 nanostructures were investigated, including the amount of original NaOH, the barium ion source, and the reaction temperature and time. Experiments showed that the as-prepared coral-like BaTiO 3 nanostructures presented good photocatalytic activity for the 15 degradation of methyl orange (MO) dye under the irradiation of the mimic sunlight. It was found that the photocatalytic activity of coral-like BaTiO 3 nanostructures could be affected by the pH value of the system.
