Low-temperature synthesis of ZnTiO3 nanopowders

N-doped TiO2/ZnO composite powder and its photocatalytic performance for degradation of methyl orange

“…Several endothermic and exothermic peaks are observed before 500°C, which means that the calcining process of the composite gel consists of a series of dehydration, decomposition, and combustion/oxidation reactions [31]. Two large exothermic peaks, corresponding to large reaction heat, are observed at 363°C and 433°C in the DTA curve for the gel sample ammonia treated with NH 3 mass fraction of 0%, in good agreement with those of 370°C and 428°C obtained in the literature [32]. In the case of that ammonia treated with NH 3 mass fraction of 28% the two peaks are at 285°C and 487°C.…”

“…Besides rutile, diffraction peaks of hexagonal ZnTiO 3 (h-ZnTiO 3 , JCPDS No. 26-1500) with strong peak intensities are observed in this case, indicating an extensive reaction [31][32][33] of ZnO þ TiO 2 À À À À À ÀZnTiO 3 :…”

Stearic acid gel derived MgTiO3 nanoparticles: A low temperature intermediate phase of Mg2TiO4

“…In a recent report on SAG synthesis of MgTiO 3 powders by Kang et al [10], the tetragonal flake-like nanocrystallites of MgTiO 3 is synthesized by SAG method. SAG method has also many distinctive advantages to prepare nanoparticles of BaTiO 3 [11,12] and ZnTiO 3 [13], such as decreasing significantly the crystallization temperature, producing high purity nanopowders, easy control of the M (M = Ba, Zn and Mg) and Ti stoichiometric ratio and low cost in comparison with other sol-gel methods [11,12].…”

Fabrication of zinc titanate nanofibers by electrospinning technique

“…Zinc titanates have been investigated for applications in many fields such as paint pigment, gas sensor and catalytic sorbent in recent years [1][2][3]. It is reported that there are three compounds existing in the ZnO-TiO 2 system including Zn 2 TiO 4 (cubic), ZnTiO 3 (hexagonal), and Zn 2 Ti 3 O 8 (cubic) [4].…”

“…Nanostructured materials have exhibited novel physical and chemical properties that can be used in optics, data-storage devices and nanoelectronic devices [1,8]. As a type of nanostructure with specific morphologies, nanofiber has been studied actively as a new functional material.…”
