an investigation was conducted on hemin modified with axial ligand loaded onto magnetic carriers which created a kind of visible-light activated photocatalyst with good magnetic property. this photocatalyst exhibits excellent photo-degradation performance and can be readily reclaimed in the degradation of bis-phenol a (bpa) in aqueous solution under visible light. the catalysts were characteriz...

Clean and drinkable water is a big challenge in 21st century. A variety of organometallic compounds have been utilized by human being for rapid civilization modernization. These hazardous waste discharges from the industries directly mixed with environment especially reservoir adulterate water, which responsible many contagious diseases. To vanquish this issue we needed an eco-friendly, safe, c...

Hollow structure LiNb3O8 photocatalysts were prepared by a hydrothermal method assisting sintering process. The particles' aggregation to form hollow structures with obvious cavities can be attributed to the Li element volatilization during calcination process. All the LiNb3O8 powders show high photocatalytic efficiency of degradation of methylene blue (MB), especially for the sample calcined a...

BACKGROUND The interactions of p-cresol photocatalytic degradation components were studied by response surface methodology. The study was designed by central composite design using the irradiation time, pH, the amount of photocatalyst and the p-cresol concentration as variables. The design was performed to obtain photodegradation % as actual responses. The actual responses were fitted with line...

This work aimed to investigate the interparticle electron transfer (IPET) process within the coupled-photocatalyst systems on the basis of the degradation of 4-chlorophenol (4-CP). TiO(2), ZnO and SnO(2) are used as the model photocatalysts owing to their increasing energy levels which correspond to the IPET concept. In the single-photocatalyst tests, ZnO tests are associated with the highest d...

For the sustainable production of hydrogen by photocatalysis, the use of renewable resources such as water, organic compounds from plant biomass and earth abundant metal promoters is desired. We herein describe the previously not reported "one-pot" photoassisted synthesis of a binary metal-nitrogen promoted Cu(0)-N-TiO2 photocatalyst from a N-TiO2 precursor by photodeposition of copper directly...

To overcome the recovery disadvantages of Bi2O3 photocatalyst in the form of powder, Bi2O3 photocatalyst coatings were developed via a ball milling, followed by the calcination method. The composition and structure evolution rules of the as-synthesized samples were analyzed based on XRD (X-ray powder diffraction) patterns and SEM (scanning electron microscope) observations. XPS (X-ray photoelec...

Stibnite (Sb2S3) semiconducting material was successfully synthesized by a rapid and facile microwave route using antimony chloride (SbCl3) and sodiumthiosulfate (Na2S2O3) dissolved in propylene glycol (PG) containing different hydroxyethyl cellulose (HEC) masses. The phase identification, morphology, and elemental composition of products were characterized by X-ray diffraction (XRD), transmiss...

Bismuth oxyiodide (BiOI) is an important photoelectric functional material that has a wide range of applications. In particular, it can be used as a photocatalyst that shows photocatalytic activity under visible-light irradiation. The synthesis procedure and related photocatalytic performance of BiOI have been reported. However, some of its fundamental properties still need to be further invest...

In this paper, we have done the photodegradation of Methyl green dye in presence of prepared Ni0.10:La0.05:TiO2 nanocomposites. The nanocomposites of Ni0.10:La0.05:TiO2 was prepared by the solution impregnation method. The characterization of Synthesized TiO2 and Ni0.10:La0.05:TiO2 nanocomposites were done by X-Ray Diffractometer, SEM, TEM, UVVis, FT-IR, Band gap energy and BET. The photocataly...
