| Abstract | ||||
| A Series of magnetite (Fe3O4) nanocomposite based efficient photocatalysts was synthesized employing coprecipitation method. Characterization of pure and different coated samples was achieved by using XRD, IR, specific surface area (SBET) and SEM techniques. The results revealed that the formation of the magnetite crystal without any impurities. The SEM images of this catalyst exhibited regular well crystalline microstructures with almost spherical shape and homogenous particle size in the range of nano scale. The presence of sodium lauryl ether sulfate (SLES) resulted in an increase in crystallinity. This increase led to a decrease in both of the particle size and the spherical shape regularity; however the particles boundary is still preserved. The as-prepared samples recorded photocatalytic activities towards degradation of organic pollutants in waste water. The sample coated with SLES displays the highest activity (with 90.1% efficiency in 180 min) due to the role of SLES. | ||||
