Synthesis of Zinc Glycerolate Microstacks from a ZnO Nanorod Sacrificial Template

Abstract

We synthesized zinc glycerolate (ZnGly) microstacks by treating ZnO with glycerol at 100°C under reflux. We observed that the morphology of the ZnO source has a pronounced effect on the appearance of the ZnGly product. In the absence of structure-directing effects the product ZnGly is obtained as a random heap of hexagonal prisms with an average diameter and thickness of ca. 2.5 µm and ca. 350 nm, respectively. However, bundles of nanorod-shaped ZnO obtained by the thermal decomposition of zinc oxalate nanorods could readily be transformed into 2-4 µm long zinc glyc-

Solvothermal Synthesis, Characterization, and Formation Mechanism of a Single‐Layer Anatase TiO2 Nanosheet with a Porous Structure

“…[24,25] Therefore, it could be concluded that, in the reaction system, glycerol served as a chelating ligand and coordinated in situ with TiOSO 4 to form the titanium glycerolate (TiGly) precursor complexes ( Figure S1), which is similar to previous reports. [26,27] After we calcined the precursors at 600°C in air for 3 h, the XRD diffraction peaks of the as-obtained products ( Figure 1B) were in good agreement with pure anatase TiO 2 (JCPDS 21-1272), revealing the phase transformation from TiGly to anatase TiO 2 . Meanwhile, TiOSO 4 ·2H 2 O can also directly convert to anatase TiO 2 after calcination [see curve (e) in Figure 1B], which is consistent with a previous report.…”

Green fabrication of 3-dimensional flower-shaped zinc glycerolate and ZnO microstructures for p-nitrophenol sensing

“…It is one of the important slow-release nontoxic sources of therapeutic zinc with antiarthritic, antiulcer, and antiinammatory activities. 35 Recently, zinc glycerolate was also found to play as heterogeneous catalyst for the synthesis of fatty acid methyl esters and formation of glycerol carbonate. 36,37 Here, it should be mentioned that polyol-mediated synthesis of ZnO was reported earlier.…”

Hexagonal and Monoclinic Phases of La2O2CO3 Nanoparticles and Their Phase-Related CO2 Behavior

“…The weight loss due to the thermal decomposition occurs at 326 °C and in the temperature range of 770–800 °C. According to previous studies [ 4 , 30 ], the CO 2 peak, which appears during the decomposition of La 2 O 2 CO 3 above 600 °C, can be assigned to CO 2 gases leaving from the bulk structure of the La 2 O 2 CO 3 phases, which is then transformed into the La 2 O 3 phase. The CO 2 decomposition from the bulk structure of the hexagonal La 2 O 2 CO 3 phase occurs at approximately 800 °C, which is higher than the temperature of CO 2 production during the decomposition of the bulk structure of the monoclinic La 2 O 2 CO 3 phase.…”

“…The CO 2 adsorption modes on each basic site have been studied by a combination of FT-IR spectroscopy and CO 2 -TPD measurements [ 31 , 32 ]. Manoilova et al [ 30 ] investigated the CO 2 adsorption onto La 2 O 3 by IR spectroscopy, TPD, and DFT calculations. The DFT calculation for the CO 2 adsorption on La 2 O 3 predicted that CO 2 gas adsorbed on the surface in the form of polydentate and monodentate species as a starting structure, and then La 2 O 3 made a stable connection with polydentate and asymmetric CO 2 adsorptions at the saturated coverage.…”
