Apr 12, 2022 In our previous reports [21, 37, 38, 41], the concentration of NaOH in the precursor solution was the key factor affecting the crystal growth of ABO 2 oxides during hydrothermal synthesis.Using Cu(NO 3) 2 3H 2 O and Ga(NO 3) 3 xH 2 O as reactants, the amount of mineralizer NaOH (samples No. 1, No. 2, No. 3 in Table 1) was adjusted to prepare CGO …
Authors: Shao Feng Yan, Xiao Hang Xiong. Abstract: F-doped TiO2 by hydrothermal synthesis method is prepared in this paper. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), infra-red (FT-IR) and diffuse reflectance spectroscopy (UV-vis). The photocatalytic performances of the samples were estimated ...
Copper oxide with various morphologies was synthesized by the hydrolysis of Cu(ac) 2 with urea under mild hydrothermal conditions. In the synthesis, a series of organic amines with one or two amine groups (monoamine and diamine), including isobutylamine, octylamine (OLA), dodecylamine, octadecylamine (monoamines), ethylenediamine dihydrochloride, and …

Dec 01, 2013 In summary, high crystalline Bi 12 TiO 20 hierarchical nanostructures are produced by microwave-assisted hydrothermal method at a lower heating temperature and shorter reaction time, relative to the conventional hydrothermal process. In the case of morphology control, assembly of the nanobelts into flower-like hierarchical structures has been ...
Dec 15, 2011 1. Introduction. Hydrothermal synthesis (or hydrothermal method) includes the various techniques of fabrication or crystallizing substances from high-temperature aqueous solutions at high vapor pressures. In case of crystallization processes, the hydrothermal synthesis can be defined as a method of synthesis of single crystals that depends on the …
Feb 16, 2016 The hydrothermal synthesis of SrTiO3 in a Sr(OH)(2)/NaOH solution by reaction of four different single crystalline titanium precursors (anatase, rutile, sodium titanate, and hydrogen titanate) having the same nanowire morphology was investigated under stagnant fluid conditions. Owing to the low solubility and dissolution rate of the parent phases, the …
