htvb}+OH--'OHOrhlvb)+H2OT"'OH+Htq [5] These active species of oxygen as well as eand ht.b) would support a wide variety of Ti02 dependent photo-induced catalytic reactions, oxidation, oxidative cleavage, reduction, geometric and valence isomerization, substitution, condensation, and polymerizatien.i) We showed here that NOi is oxidized by・OH and reduced by e', producing NOi and NO, respectively...

Currently, the textile industry is one of the most important economic sectors in many countries. Besides, it is known as a major consumer of water and consequently one of the largest groups of industries causing intense water pollution. Chemicals, including surfactants, dyes, resins, dispersants agents, inorganic salts, etc., play a variety of functions during the textile processing and are pre...

Abstract Silver orthophosphate (Ag 3 PO 4 ) is an attractive photocatalytic catalyst for disinfection and degradation, but its instability arising from silver release generates significant environmental issue. Aiming to develop a highly efficient environmental-friendly catalyst, we synthesized Ag nanoparticle incorporated hierarchical porous silica @ h -SiO 2 as novel high-performance without o...

Potentiodynamic discharge measurements of hematite photoanodes, supported by micro-kinetic modeling, indicate that parallel reaction pathways prevail in water photo-oxidation. Their co-existence may lead to collective phenomena with complex dynamics.

Abstract Oil is a complex mixture of alkanes, cycloalkanes, aromatics, nitrogen/sulfur/oxygen (N/S/O) heterocycles, alcohols, ketones, carboxylic acids, porphyrins, and myriad possible combinations therein. Once introduced into the environment, some weathering processes reduce this complexity through evaporative losses (loss to atmosphere) as well water washing low ring number N/S/O acids seawa...

In this research paper a novel Ultra Violet Photo Catalyst Oxidation (UVPCO) sensor for air and surface sanitization using Common Source (CS) amplifier is presented. The ultra violet photo catalysis is the process in which the highly reactive radicals like H+, OH-and peroxides ions are produced from air in the presence of the ultra violet radiation and photo catalyst. In this process, the free ...

Degradation products formed during removal of an aqueous nonylphenol ethoxylate compound (NP-10) by the H2O2/UV-C, Fenton (Fe/H2O2) and photo-Fenton (Fe/H2O2/UV) advanced oxidation processes and their relationship with the acute toxicity toward Vibrio fischeri photobacteria were investigated. Polyethylene glycols with 3-8 ethoxy units, aldehydes and carboxylic acids were identified as the prima...

Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. New technologies have been developed in the last decades and in particular Advanced Oxidation Processes (AO...

We present the rational synthesis of nanoporous CuS for the first time by chemical dealloying method. The morphologies of the CuS catalysts are controlled by the composition of the original amorphous alloys. Nanoporous Cu2S is firstly formed during the chemical dealloying process, and then the Cu2S transforms into CuS. The nanoporous CuS exhibits excellent photocatalytic activity for the degrad...
