Synthesis, characterization, and morphological control of Na1/2Bi1/2Cu3Ti4O12 through modify sol–gel method

Abstract

This paper describes the synthesis of Na 1/2 Bi 1/2 Cu 3 Ti 4 O 12 (BNCTO) with different morphologies like nanoparticles, micro cubic, and micro sheet structure prepared by modify sol-gel method, using different surfactants (SDS, CTAB, PVP, and PVA). This study aimed to investigate the effects of different surfactant such as SDS, CTAB, PVP, and PVA and chelating agent on the morphology and particle size of final products. It was found that the size and morphology of the products could be greatly influenced by the aforementioned parameters. To our knowledge, this is the first report on the synthesis of Na 1/2 Bi 1/2 Cu 3 Ti 4 O 12 nanostructure with different morphologies in the presence of salicylic acid as a chelating agent. The as-synthesized products were characterized by powder X-ray diffraction, scanning electronic microscopy, ultraviolet-visible, and energy dispersive spectrometry analysis of X-ray techniques.

Enhancing giant dielectric properties of Ta5+‐doped Na1/2Y1/2Cu3Ti4O12 ceramics by engineering grain and grain boundary

“…For the Acu 3 Ti 4 O 12 family, CdCu 3 Ti 4 O 12 , 24–27 B 3/2 Cu 3 Ti 4 O 12 , 28,29 Na 1/2 Y 1/2 Cu 3 Ti 4 O 12 (NYCTO), 30–33 Na 1/2 Bi 1/2 Cu 3 Ti 4 O 12 , 34 Na 1/3 Ca 1/3 Y 3/2 Cu 3 Ti 4 O 12 , 35 Na 1/3 Ca 1/3 Bi 1/3 Cu 3 Ti 4 O 12 , 36 Na 1/3 Cd 1/3 Yi 1/3 Cu 3 Ti 4 O 12 37 , and Na 1/3 Cd 1/3 Bi 1/3 Cu 3 Ti 4 O 12 38 ceramics have been widely reported due to their low tanδ values as compared to those of CCTO ceramics. However, the dielectric properties measured for this group of systems hamper their applications as electronic devices because of their high tanδ value (>0.03).…”

Synthesis and characterization of gold nanoparticles with the aid of green reducing agent through the free surfactant microwave method

“…where a is absorption coefficient, hm is the photon energy, a0 and h are the constants, E g is the optical band gap of the material, and n depends on the type of electronic transition and can be any value between and 3 [26]. The E g value is calculated as 3.1 eV (400 nm) for the Au (sample 1).…”

Synthesis of Ag-doped PbTiO3 nanoparticles: feasibility study of its decolorization of simulated methyl orange dye wastewater

“…Nanoparticles are expected to play a crucial role in water purification [3][4][5][6][7]. In the current era, the preparation of lowdimensional nanostructures has been intensively pursued because of their useful applications in various areas [8][9][10][11][12]. Lead titanate ferroelectric material (PbTiO) or simply PT, presents dielectric, pyroelectric, and piezoelectric properties of large technological and scientific importance [13,14].…”
