“…The sharp peaks at 1625 and 1384 cm −1 are due to the asymmetric and symmetric stretching vibration absorptions of bi-dentate acetate complex, 33 34 indicating the Mn-acetate complex is formed in the Li-Mn gel. According to previous work, 30 35 the stretching vibration absorptions of nitrate should be around 1384 and 1067 cm −1 , which may be overlapped in this spectrum. Figure 3(b) shows the FTIR spectra of typical calcined samples.…”

“…28 Just like other chelating agents, 29 acetic acid also acts as a fuel for calcination in the synthesis of oxide powders. The second step, corresponding to two peaks of 230 and 383 C in the DTG curve accompanied by weight loss of 23%, was observed from 210 to 400 C. It is related to the decomposition of nitrate, 30 the further combustion of organic substances in the gel together with the formation of spinel phase LiMn 2 O 4 . The last step is observed over 400 C. The weight loss in this step is not obvious, indicating that the decomposition of organic substances has nearly been completed.…”

LiMn 2 O 4 is a potential cathode material used in lithium ion batteries due to its satisfactory capacity, high energy density, low self-discharge rate and high thermal stability. In this work, submicron-sized LiMn 2 O 4 was successfully prepared at low temperature by sol-gel method employing acetic acid as a chelating agent. The as-prepared Li-Mn gel was analyzed by thermal gravimetric analysis (TGA), and the calcined samples were further characterized by X-ray diffraction (XRD), Fourier transform infrared spectrometry (FTIR), Raman spectroscopy (RS), and field emission scanning electron microscopy (FESEM), respectively. The results show that high purity spinel-type LiMn 2 O 4 with good crystallinity can be successfully prepared at a wide low temperature range from 600 to 800 C. SEM shows that the typical sample is irregular particles adhered by submicronsized primary particles, and the average size of the primary particles is 0.37 m. The LiMn 2 O 4 sample exhibits good reversibility and rate capability. The cyclic voltammetry (CV) and charge/discharge studies also reveal that the intercalation and de-intercalation of lithium ions occurs in two stages. The present work develops a facile and low temperature way to prepare submicron-sized LiMn 2 O 4 with good crystallinity and some good electrochemical behavior.

“…These properties enable a wide spectrum of technological applications, e.g., in catalysis [8][9][10][11][12][13][14][15]. BTOs have been synthesized as thin films [16][17][18] and nanostructured powders with solid-state and wet-chemistry synthesis routes, which include calcination [19], coprecipitation [20], hydrothermal [21], sonochemical [22], and mechanochemical methods [23,24], among others.…”

Bismuth titanate (BTO) nanoparticles were obtained by pulsed laser ablation in liquid media (PLAL). Distilled water, ethanol, isopropanol, and acetone were used as media for laser ablation experiments, in which the colloidal solutions were obtained. Laser ablation was carried out using the second harmonic and fundamental wavelength of a pulsed Nd:YAG laser (532 nm and 1064 nm, respectively) with laser fluences of 25 and 12 mJ/cm2, respectively. Transmission electron microscopy was utilized for morphological characterization. BTO nanoparticles obtained have spherical shapes with orthorhombic structure and the average size distribution depended on the liquid media nature. In alcohols, BTO NPs were spherical with a carbon layer around them. X-ray diffraction, UV-Vis absorption spectra, and X-ray photoelectron spectroscopy were used to confirm the structural, optical, and elemental properties of the ablated products. The presented results show that PLAL is a viable technique for the synthesis of high-quality BTO nanoparticles with enhanced optical properties for possible applications in photocatalysis.
