“…The high‐resolution spectra of individual elements are presented in Figure . The Mg species is observed by the presence of Mg 2p, Mg 2 s, Mg KLL, and Mg 1s state corresponding to the binding energies of 52.8, 90.8 306.8, 351.8 and 1302.8 eV . The high‐resolution spectra of Mg 1s is fitted with three components corresponding to the binding energies of 1307, 1308 and 1308.8 eV which are attributed to Mg, Mg–CO 3 and MgO respectively ,.…”

Herein, we report the preparation and visible light-triggered photocatalytic investigation of nitrogen-rich graphitic carbon nitride (g-C 3 N 4 ) nanosheets intercalated ZnO\MgÀ Al LDH (2D \2D) ternary nanocomposite. The ZnO nanoparticles, unique structured LDH, and g-C 3 N 4 are intercalated well by the hydrothermal treatment, showing a significant enhancement in the visible light absorption and corresponding photocatalytic activity. Formation of this new ternary nanocomposite was examined by using XRD, FE-SEM, TEM, FTIR, EDX, Elemental mapping, XPS and UV-Vis analysis. The ternary nanocomposite photocatalyst show remarkable performance towards the photodegradation of Methylene Blue (MB) dye. The ternary nanocomposite exhibited considerable improvement in the photocatalytic activity and is attributed to the N-rich g-C 3 N 4 and even distribution of ZnO\MgÀ Al LDH over the g-C 3 N 4 surface. This work offers a facile approach to prepare a novel visible light-response photocatalyst for photocatalytic dye degradation of organic pollutants.

“…The spectroscope was equipped with AlK α source, pass energy was 30 eV and the spot size diameter 250 micrometre. Charge compensation was controlled through the low-energy electron and low-energy Ar + ion emission by means of a flood gun (emission current 150 mA, beam voltage 2.1 V, filament current 3.5 A), with normalisation of the X-axis (binding energy) for the peak characteristics of neutral carbon C 1s (284.6 eV) [17,18]. For deconvolution purposes Avantage software (Thermofisher Scientific) was used.…”

A glassy sample with a nominal formula LiMn 1−3x/2 V x BO 3 (where x = 0.05) was synthesised using the melt-quenching method. Material was characterised by differential thermal analysis (DTA), X-ray diffactometry (XRD) at room temperature and as a function of temperature (HT-XRD), X-ray photoelectron spectroscopy (XPS), impedance spectroscopy (IS) and scanning electron microscopy (SEM). Dependences of glass transition and crystallisation temperatures on the heating rate in DTA experiments were determined. The initial value of electrical conductivity of the glass was 1.4 × 10 −15 Scm −1. It was significantly increased by a proper thermal nanocrystallisation. The maximum value was higher by 6 orders of magnitude and reached 2.6 × 10 −9 Scm −1 at room temperature. Expected crystalline phases (i.e. monoclinic and hexagonal LiMnBO 3) upon heating were identified and assigned to thermal events observed with DTA. Microstructure of nanocrystalline samples observed by SEM revealed nanocrystalline grains noticeably smaller than 100 nm. Results explaining nanocrystallisation process are coherent.
