https://www.selleckchem.com/products/PD-0332991.html With the aim of improving the photocatalytic activity for water splitting, novel core-shell-structured crystalline-BaTiO3/amorphous-BaTiO3-x/crystalline-CdS composite nanocubes are prepared by a facile two-step synthesis approach. Basic characterization techniques such as X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy and transmission electron microscopy are carried out on the as-prepared composite nanocubes in order to confirm the quality of their crystal structure, morphology and chemical components correspondingly. UV-Vis-NIR measurements of the as-prepared composite nanocubes validate the presence of extended visible-light absorbance due to oxygen-deficient BaTiO3-x. Photoelectrochemical tests are carried out on the as-prepared nanocomposite films that are coated directly on indium tin oxide (ITO) glass substrates. The as-prepared composite nanocubes show a photocurrent density of 100 μA cm-2 without electric field poling, whereas they show about 200 μA cm-2 with an electric field poling of 18.8 kV cm-1. This study suggests that the photoelectrochemical performance is highest in our prepared BaTiO3/BaTiO3-x/CdS composite film compared to the pure BaTiO3, CdS and BaTiO3/BaTiO3-x films, and it may offer a new potential route for designing cost-effective, highly stable and efficient photocatalysts.Manganese(ii) halide complexes with N,N,N',N'-tetramethyl-P-naphtalen-2-ylphosphonic diamide were synthesized from anhydrous MnX2 salts (X = Cl, Br, I) and characterized. Single-crystal X-ray diffraction revealed in all the cases slightly distorted tetrahedral geometry of the coordination sphere. The photoluminescence spectra showed the superimposition of a green emission, related to the 4T1(4G) → 6A1(6S) transition of Mn(ii), with a band in the red range. Different possible attributions to the lowest-energy emission were taken into account. The emission spectra of the isolated pro
