As climate change progresses, there is an increasing interest on the use of non-conventional water sources such as brackish or saline waters. Nowadays, main threat in Europe detected these waterbodies nitrate contamination. Within multiple available methods studied for reduction, photocatalysis presents promising results, but this technology has not yet been tested water. This work tackles elim...

Background & Aims of the Study: In this study, 4-(2-pyridylazo) resorcinol (PAR) as model azo dye was used. In spectroscopic measurements and studies of PAR reagent as a ligand are used to formation a complex with toxic metals. So, removal and degradation these compounds of wastewaters are necessary. The aim of this study is the degradation of PAR from aqueous solutions in circulating fludized ...

There is growing recognition that cooperative effects exist under dual-mode (photo-thermal) heterogeneous catalytic excitation offer genuine prospects in the transition to a sustainable energy and chemicals economy. Solar beams can act as practical combined source of photons heat (via non-radiative relaxation after optical absorption) lead process intensification. This review provides critical ...

Zinc oxide nanoparticles (ZnO NPs) is unique studied semiconductor substance for photocatalytic utilization like light-emitting diodes, solar cells, photo-diode, sensor, and photo-detector. The ZnO ratio of surface to volume as increases with reduces size afford an increase improve the reactivity surface. Among all possible approaches preparation, sol-gel process individual simple synthesis met...

Highly efficient recyclable photocatalysts of ternary g-C 3 N 4 -ZnO/Cu 2 O nanocomposite were designed for photo-degradation RhB dye. The structural, morphological, surface structure and optical properties the as-prepared nanocomposites (NCs) characterized by XRD, FT-IR, FE-SEM with EDS, HRTEM, XPS, BET, UV–Vis DRS PL spectra analysis respectively. efficiencies dye over , /ZnO, /Cu (PCs) 36.4%...

This paper is a definition of photo elicitation and a history of its development in anthropology and sociology. The view of photo elicitation in these disciplines, where the greatest number of photo elicitation studies have taken place, organizes photo elicitation studies by topic and by form. The paper also presents practical considerations from a frequent photo elicitation researcher and conc...

The specific roles played by both support and noble metals in light absorption, charge separation, the formation of ·OH O2− (ROS) are analyzed for light-triggered oxidation phenol (Ph) over pristine metal (Ag, Au, Pt) -loaded TiO2. Experiments show that supported act as a visible absorber, assist separation photo-charges reduction O2 to O2−. oxidizes mildly Ph oxygenated products (hydroquinone,...

in this research degradation and mineralization of ortho-toluidine (ot) in the wastewater of petrochemical industries was investigated by uv/tio 2 process in a batch recirculating photo reactor. the influence of different variables such as initial ph, amount of tio 2 and initial concentration of ot on the reaction rate was investigated. in optimum conditions (1.75 g/l of catalyst, ph at 7 and i...

In article number 2008244, Jorge Gascon and co-workers report complete visible-light photo-thermal CO2 conversion to methane using a new composite catalyst based on Ni nanoparticles supported barium titanate. Under optimal conditions, the photocatalyst displays an outstanding CH4 production rate of 103.7 mmol g−1 h−1 derived from its excellent performance light harvesting properties.

In this work, H3PW12O40 (PPT) and nano-sized titania supported on urea formaldehyde (UF) resinwas prepared via an impregnation method. The prepared sample was characterized by X-raydiffraction (XRD), UV-Vis spectrophotometer, Fourier transform infrared spectroscopy (FT-IR),scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The photocatalyt...
