In this study, we report the facile fabrication of Fe(2)O(3)/CQDs nanocomposites, and investigate their effective photocatalytic activity for the photodegradation of toxic gas (gas-phase benzene and methanol) under visible light. The crucial roles of CQDs in the enhancement of photocatalytic activity of the Fe(2)O(3)/CQDs composites are illustrated.

Exposure to solar radiation substantially decreased the strong copper-complexing capacity of samples collected from the organic-rich Cape Fear estuary, North Carolina. Samples exposed to natural sunlight for 1–2 d experienced a loss of strong Cu ligand (modeled at fixed K9CuL 5 1013.5) ranging from 15–33%, and .90% using long-term exposures under controlled conditions with a Xe arc solar simula...

An on-line automated method for photodegradation studies of isoproturon, diuron, atrazine, fenitrothion, and metoxuron by means of liquid chromatography/mass spectrometry (LC/MS) with particle beam (PB) interface is described. Surface water samples were first spiked with 50 µg/l of each pesticide and then exposed to the radiation of the medium-pressure mercury lamp. Next, in regular intervals o...

The artificial neural network (ANN) modeling of m-cresol photodegradation was carried out for determination of the optimum and importance values of the effective variables to achieve the maximum efficiency. The photodegradation was carried out in the suspension of synthesized manganese doped ZnO nanoparticles under visible-light irradiation. The input considered effective variables of the photo...

Plasmonic photocatalytic nanostructures have been fabricated under mild conditions (room temperature aqueous solution) using genetically engineered bacteriophage P22 virus-like particles (VLP) as a nano-platform. The photodegradation of methylene blue by CdS photocatalyst confined inside VLP can be significantly enhanced by the controlled deposition of gold nanoparticles on the outer shell of V...

A novel Ag-based photocatalyst Ag2Nb4O11 has been obtained, which exhibits universal high-efficiency photodegradation activity for rhodamine B (RhB), methylene blue (MB) and methyl orange (MO) organic dyes. The cycling ability (40 times) and recovery characteristics indicate that the Ag2Nb4O11 photocatalyst has high stability, durability and regeneration ability.

The photodegradation properties of six electro-optic chromophores in guest-host polymer formats were measured as a function of wavelength throughout the visible and up to 1.3 ␮m in the near infrared. The chromophore structure was varied to provide insight into its relationship with photostability.

An effective, template-free synthesis methodology has been developed for preparing mesoporous nitrogen-doped SrTiO(3) (meso-STON) using glycine as both a nitrogen source and a mesopore creator. The N-doping, large surface area and developed porosity endow meso-STON with excellent activity in visible-light-responsive photodegradation of organic dyes.

The unique optical properties of the fluoropolymer microcapillary film (MCF) material combined with the extremely fast photoinactivation of Herpes HSV-1 virus, and photodegradation of indigo carmine, diclofenac and benzoylecgonine in the MCF array photoreactor, demonstrate a new, flexible and inexpensive platform for rapid photochemical transformations, high-throughput process analytics and pho...

The structures of the new anthraquinone antitumor antibiotic DC92-B and its photodegradation product DC92-D were determined by their spectral studies. DC92-B and D are pluramycin antibiotics, related to hedamycin which possess a characteristic ring F and a side chain containing a cis-epoxide and terminal dimethyl.
