The photocatalytic activity of meso-tetraphenylporphyrins with different metal centers (Fe, Co, Mn and Cu) adsorbed on TiO(2) (Degussa P25) surface has been investigated by carrying out the photodegradation of methyl orange (MO) under visible and ultraviolet light irradiation. The photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectan...

Comparison of the methyl orange method of estimation of serum albumin with sodium sulfate fractionation and electrophoretic fractionation on paper showed that the sodium sulfate method may occasionally give much lower results than the other two. This may be due to loss of albumin on the precipitated globulins. Of the three, the methyl orange method tended to give the highest results, but was ap...

CdIn2S4 was prepared by ultrasonic spray pyrolysis. The prepared CdIn2S4 was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FSEM), transmission electron microscopy (TEM), UV-visible diffuse reflectance spectroscopy (UV-Vis DRS), and N2-sorption techniques. Aqueous photocatalytic activity was evaluated by the decomposition of methyl orange under visible li...

Acid-etched graphitic carbon nitride (TGCN) nanosheets decorated with polyaniline (PANI) nanofibers for the adsorption and photocatalytic degradation of Methyl Orange (MO) Congo Red (CR) toxic textile dyes.

The adsorbent for both cationic and anionic dye based on cellulose polyaniline was prepared. Cellulose purified from sugarcane bagasse through the removal of hemicellulose lignin. Aniline polymerized in emulsion state presence ammonium persulfate as an initiator. results Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM) observation determination porosity confirm...

Both energy band and charge separation and transfer are the crucial affecting factor for a photochemical reaction. Herein, the BiOCl nanosheets without and with surface bismuth vacancy (BOC, V-BOC) are prepared by a simple hydrothermal method. It is found that the new surface defect states caused by bismuth vacancy have greatly up-shifted the valence band and efficiently enhanced the separation...

Plate- and octahedron-like Pt/Bi5Nb3O15 heterostructures are controllably prepared by a hydrothermal treatment method combined with photodeposition in the presence of different surfactants, i.e., cetyltrimethylammonium bromide (CTAB) and polyvinylpyrrolidone (PVP). The composition, structure, morphology, optical absorption properties, and textural properties of as-prepared Pt/Bi5Nb3O15 are well...

To improve the photocatalytic efficiency and make full use of solar energy, ZnWO(4):Yb(3+),Tm(3+) (ZYT) was introduced as the upconversion luminescence agent on TiO(2) with a cotton template, and novel upconversion photocatalysts of TiO(2)/ZnWO(4):Yb(3+),Tm(3+) (TZYT-C) were synthesized and optimized with 5%-30% of ZYT. The heterostructure between ZYT and TiO(2) was formed in the TZYT-C composi...
