The microstructure, morphology, and optical properties of studied XRD, FTIR, XPS, SEM, TEM, UV–Vis DRS, PL. degradation rate 20 mg/L norfloxacin (NOR) under visible light for 3 h adopted as one indexes to evaluate photocatalytic perf...

N-doped TiO2, denoted as T_400, was prepared simply by the facile thermal hydrolysis of TiOSO4 using NH4OH both a precipitating agent and nitrogen source. Compared to TiO2 without doping, T_400 provides superior photocatalytic activity toward selective oxidation benzyl alcohol benzylamine under visible light irradiation, with > 85 % conversion 95 selectivity benzaldehyde N-benzylidenebenzylamin...

biocl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (mw) assisted synthesis method for 23 minutes at 180 w. scanning electron microscopy (sem) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. the x-ray diffraction (xrd) pattern showed that a highly pure and crystalline phase has been obtained. the energy ...

a useful nanophotocatalyst (la,s-tio2) was prepared by a sol-gel method and characterized by uv–vis diffuse reflectance spectroscopy (drs), x-ray diffraction (xrd), photoluminescence emission spectroscopy (pl) and scanning electron microscopy (fesem). the results showed that the la,s-tio2, which calcined at 550 °c, contained only anatase phaseand its crystal size was 23 nm. in addition, the fes...

α-NiS/g-C3N4 nanocomposites were synthesized and used for photocatalytic hydrogen (H2) evolution tetracycline hydrochloride (TC) degradation. The fabricated characterized by XRD, XPS, SEM, TEM, UV-vis DRS, TRPL, PEC measurements. Photocatalytic studies show that the generation rate of 15%-α-NiS/g-C3N4 nanocomposite reaches 4025 μmol·g−1·h−1 TC degradation 64.6% within 120 min, both which are hi...

The nanoparticles of gold doped with various percentage of copper (Cu 10%, 25%, 75%) were synthesized by wet-chemical method at room temperature. Copper (II) sulfate and gold (III) chloride trihydride was taken as the metal precursor and ascorbic acid as a reducing agent and anhydride maleic as surfactant. The reaction is performed with high-speed stirring at room temperature under nitrogen atm...

La3+ and Sm3+ - doped Bi2Mn2O7 nanocatalysts were synthesized in 1 M NaOH aqueous solution, via a stoichiometric 1:1 Bi:Mn molar ratio hydrothermal method at 180 °C for 48 h. Bi(NO3)3, MnO2, La(NO3)3 and Sm2O3 were used as raw materials. The synthesized nanomaterials were characterized by powder X-ray diffraction (PXRD) technique. Both of the La3+ and Sm3+ - doped Bi2Mn2O7 nanomaterials were cr...

nanocomposites of multi-walled carbon nanotubes and titanium dioxide (mwcnt/tio2) were synthesized by the sol-gel method. regarding hydrophobicity of carbon nanotubes (cnts), benzyl alcohol was used as the linking agent between cnt powder and tio2 gel which was prepared from the precursor of titanium tetraisopropoxide. the prepared samples were treated under thermal treatments. a part of the sa...
