Abstract Praseodymium doped TiO 2 nanoparticles were successfully prepared by the sol–gel method and characterized X-ray powder diffraction, N adsorption–desorption isotherm, UV–vis spectroscopy. The effects of dopant on crystallite size, specific surface area, average pore diameter, volume, bandgap energy investigated. photocatalytic activity catalysts was evaluated bisphenol A degradation min...

The aim of this work was to investigate effect of operational parameters on the photocatalytic degradation efficiency of a solution containing C. I. Basic Blue 41 BB41 in a recirculated rectangular photoreactor irradiated with a UV light. TiO_2 nano composite film was prepared via sol-gel dip coating method. The films were characterized by X-ray diffraction XRD, transmission electron microscopy...

the photocatalytic degradation of a common analgesic (acetaminophen) with titanium dioxide irradiated with low energy ultraviolet light (365 nm) was studied in order to determine the effect of several parameters such as catalyst’s weight, photochemical effect, and initial concentration. the results indicate that acetaminophen is degraded in the order of 4% by the photochemical effect. the pres...

Photocatalytic removal of single volatile organic compounds (VOCs) has been widely investigated; however, photodecomposition VOC mixtures rarely addressed, which may bring safety doubts in indoor air purification due to possible formation harmful compounds. Here we show that photocatalytic oxidation formaldehyde–toluene and formaldehyde–xylene mixtures, the introduction Pd cocatalyst on TiO2 ph...

A plasmonic photocatalyst Ag-AgI supported on mesoporous alumina (Ag-AgI/Al(2)O(3)) was prepared by deposition-precipitation and photoreduction methods. The catalyst showed high and stable photocatalytic activity for the degradation and mineralization of toxic persistent organic pollutants, as demonstrated with 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP), and trichlorophenol (TCP) under...

NPS SYNTHESIS, CHARACTERIZATION AND AZO-DYE DEGRADATION A facile cost effective wet chemical method of synthesis is proposed for Cu-NPs, CuO-NPs and Cu-doped ZnO-NPs. The nanomaterials are opto-physically characterized for nano standard quality. Cu-doped ZnO-NPs based catalytic system is found to possess most efficient photocatalytic activity in degradation of two organic azo-dyes namely methyl...

Bi1-xBaxFeO3 (x = 0.02, 0.04 and 0.07) multiferroic materials with a diameter in the range of 30-40 nm were controllably synthesized by a facile ultrasonic method, with a very short reaction time of 5 min at a low temperature of 30 °C, and the resulting BiFeO3 magnetic nanoparticles (BFO MNPs) exhibited enhanced magnetic and photocatalytic performance. The substitution of Ba2+ ions for Bi3+ ion...
