The synthesis and characterization of title complexes of the ligand Quinolino[3,2-b]benzodiazepine (QBD) and Quinolino[3,2-b]benzoxazepine (QBO) are reported. The complexes have been characterized by elemental analysis, molar conductance, magnetic studies, IR, H1 NMR, and UV-visible studies. They have the stoichiometry [ML2C12], where M=Co(II)/Ni(II), L=QBD/QBO, and [MLC12], where M=Zn(II)/Cd(I...

Synthesis of Ag2S from AgCl waste argentometric titration with heating temperature variations as a sensor has been done. This study aims to synthesize and examine the effect on crystal quality electrical characteristics based Negative Temperature Coefficient (NTC). synthesis was carried out by precipitation in water bath various temperatures 40°C, 60°C, 80°C. The success confirmed X-Ray Diffrac...

BiOCl/BiOBr/rGO ternary heterojunctions were synthesized and characterized, their photocatalytic activities examined. Three different rGO mass ratios incorporated into BiOCl75%BiOBr25%; 1% rGO, 3% 5% respectively. The successful incorporation of the composites was confirmed using powder X-ray diffraction (PXRD). Furthermore, calculated band gap, elemental composition, composites’ morphology inv...

A CuO-loaded SrTiO3 catalyst showed highly photocatalytic activity for H2 evolution. This was prepared by an impregnation method and characterized XRD, TEM, BET, XPS, Uv-vis DRS PL techniques. Under optimum conditions, the best rate of evolution is 5811 µmol h?1g?1, whereas it a mere 34 h?1g?1 pure SrTiO3. High efficiency, low cost good stability are some merits that underline promising potenti...

Several different evaluation methods (EM) to obtain the band gap energy (Eg) of semiconductors via UV/Vis diffuse reflectance spectroscopy (DRS) are used in literature and no clear consensus which EM use is established. By using P25 as a model semiconductor, evaluating 32 sources our own experiments, we show that determined Eg heavily influenced by (differences up 0.87 eV). For loaded with CuO ...

Copper nanoparticles/fluorine-doped tin oxide (FTO) nanocomposites were successfully prepared by a simple hydrothermal method. The synthesized nanocomposites were characterized by X-ray diffraction (XRD), UV-visible diffuse-reflectance spectrum (UV-VIS DRS), energy dispersive X-ray (EDX), transmission electron microscopy (TEM), Raman spectra, and X-ray photoelectron spectroscopy (XPS). The obta...

Magnetically separable Fe3O4/AgBr hybrid materials with highly efficient photocatalytic activity were prepared by the precipitation method. All of them exhibited much higher photocatalytic activity than the pure AgBr in photodegradation of methyl orange (MO) under visible light irradiation. When the loading amount of Fe3O4 was 0.5 %, the hybrid materials displayed the highest photocatalytic act...

A heterojunction AgBr/Ag/AgCoO2 nanocomposite was synthesized by hydrothermal followed deposition precipitation method. The morphology, crystallinity and band structure of the nanoparticles were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) UV–Vis diffuse reflectance spectroscopy (UV DRS). beads prepared coating material on petrocoke with aid chitosan. performa...
