In contemporary research, “Heterostructure” assemblies play an important role in energy conversion systems, wherein the composite assemblies facilitate faster charge carrier transport across the material interfaces. The improved/enhanced efficiency metrics in these systems (electro/photo-electrochemical processes/devices) is due to synergistic interaction and synchronized charge transport a...

The heterogeneous photo-Fenton degradation of coomasie brilliant blue R–250 under visible light has been investigated using copper modified iron oxide, which has been prepared by coprecipitation method and characterized by IR spectroscopy, scanning electron microscopy and X-ray diffraction. The rate of photocatalytic degradation of dye follows pseudo-first order kinetics. The effects of various...

The photo-oxidation process by combination of UV light and H20 2 generates hydroxyl radicals which are capable of oxidising many organic compounds which are refractory type and difficult to oxidize by conve nt ional' chemical treatment. In the present study, photo-oxidation of Direct Yellow 12 (DY 12) dye has been carri ed out in an annular type photoreactor using 8 Watt low pressure mercury la...

Methylammonium lead halide perovskites are attracting intense interest as promising materials for next-generation solar cells, but serious issues related to long-term stability need to be addressed. Perovskite films based on CH3NH3PbI3 undergo rapid degradation when exposed to oxygen and light. Here, we report mechanistic insights into this oxygen-induced photodegradation from a range of experi...

Chemically Losartan is {2-N-butyl-4-chloro-5-hydroxymethyl-1-[(2′(1H-tetrazol-5-yl)biphenyl-4-yl)methyl]imidazole}. it is a typical angiotensin II (Ang II) type I receptor (AT1R) blocker that has been used for regulation of blood pressure and fluid homeostasis. Forced degradation studies are used to identify reactions which may occur to degrade a processed product. Usually conducted before fina...

Methyl orange (MO) can be degraded by a photocatalytic process using TiO₂ under UV irradiation. The photo-generated holes and electrons can migrate to the surface of TiO₂ particles and serve as redox sources that react with adsorbed reactants, leading to the formation of superoxide radical anions, hydrogen peroxide and hydroxyl radicals involved in the oxidation of dye pollution. Here, we fabri...

Mesoporous amorphous and nanocrystalline titanium dioxide were prepared by simple and environmental friendly modified Sol-Gel method using cationic (C14TAB, C16TAB, C18TAB) and nonionic (Plantacare UP K55) surfactant as pore forming agent. The obtained particles were characterized by BET, TEM, FT-IR and XRD techniques. The effect of cationic surfactant chain...

A novel visible light-driven photocatalyst film, MoS₂/Ag/TiO₂, was synthesized on a glass-fiber membrane. The composite catalyst film had a multi-layer structure with Ag as nanoconjunctions between the MoS₂ and TiO₂ layers. The catalyst film performed well for both photocatalytic hydrogen production and organic degradation in a two-chamber photo-reactor under either solar or visible light. Hydr...

A photochemical treatment with UV multi-wavelength irradiation was applied to investigate the degradation of saponins mixture obtained from alfalfa leaves. The photo-degradation studied in an aqueous solution at a pH range 4–7 and temperature 20–80 °C. samples were irradiated for 80 min using mid-pressure mercury lamp emission wavelengths between 250 740 nm. dependence absorbed radiation on con...

Fe3O4/CuO/ZnO nanocomposites with different molar ratio were synthesized using sol-gel method. The as-synthesized samples were characterized by X-ray diffraction (XRD), UVvisible spectroscopy, BET surface area analyszer, and Electron Spin Resonance (ESR). The sonocatalytic-photocatalytic-sonophotocatalytic activity of as-synthesized samples was investigated based on methylene blue degradation. ...
