In this study, the photocatalytic degradation of azo-dye acid orange 10 was investigated using titanium dioxide catalyst suspension, irradiation with ultraviolet-C lamp and bismuth vanadate under visible light of light-emitting diode lamp. Response surface methodology was successfully employed to optimize the treatment of acid orange 10 dye and assess the interactive terms of four factors. The ...

To the best of our knowledge this is the first report in which ruthenium doped polycrystalline lanthanum manganite, LaMn1-xRuxO3 (x = 0.0-0.4), having high efficacy for oxygen production from water without the use of any sacrificial reagent or co-catalyst and as an efficient photocatalyst for dye degradation is reported. Ruthenium doping alters the crystal structure of the parent LaMnO3 (LMO) d...

Copper sulfide nanotubes and nanoparticles have been successfully synthesized by a hydrothermal process at 160 °C for 10 h, employing copper chloride (CuCl2·2H2O) and thioacetamide as starting materials, polyethylene glycol 400 as surfactant. The products are characterized by X-ray power diffraction, scanning electron microscopy, UV–vis spectroscopy and fluorescence spectroscopy, respectively. ...

We demonstrate ultrathin self-assembled Cu2MoS4 nanobelts synthesized by using Cu2O as the starting sacrificial template via a hydrothermal method. The nanobelts exhibit strong light absorption over a broad wavelength spectrum, suggesting their potential application as photocatalysts. The photocatalytic activity of nanobelts is evaluated by the degradation of Methyl Orange (MO) dye under visibl...

The photocatalytic degradation of methylene blue was investigated with TiO2 and Fe2O3 nanoparticles supported on natural zeolite. The synthesized photocatalyst was characterized by XRD, XRF, FT-IR, EDX, FE-SEM, and BET analyses. The results of XRD, FT-IR, and EDX confirmed the successful loading of Fe3+ doped TiO2 nanoparticles on natural zeolite. Further, the FE-SEM results confirmed the depos...

in this paper cufe2o4, nanocrystalline powders were prepared. also, the supported cu ferrite was obtained by impregnation of the supports with cu and fe nitrates solutions, for calcination temperature 450 ºc. the samples were characterized by x-ray powder diffraction (xrd) and fourier transform-infrared spectroscopy (ft-ir). in this investigation photocatalytic degradation of acid red 206 in wa...

The contamination of organic dye molecules in aquatic environments caused by the effluents released from vast industrial establishments has been a matter serious concern recent years, owing to their strong non-biodegradable nature and acute toxicity. Semiconductor-mediated visible-light-driven photocatalytic-dye detoxification is considered as sustainable technique because it abundantly utilize...

Nitrogen-doped g-C 3 N 4 /CoS nanocomposites have been synthesized using a facile polycondensation-hydrothermal method and showed improved photocatalytic activity for the degradation of MB dye industrial real samples with good photostability.

Using reduced graphene oxide (rGO) as a template and high temperature sol-gel chemistry, we have prepared LaFeO3 nanoparticles (NPs). The 15 nm LaFeO3 NPs have a bandgap of 1.86 eV and the LaFeO3-rGO can function as an efficient catalyst for degradation of methylene blue (MB) or Rhodamine B (RhB) under visible-light irradiation with the electron transfer from the dye to hole dominating the oxid...
