The applicability of electro-Fenton technology to remediation of wastewater contaminated by several organic pollutants such as dyes and polycyclic aromatic hydrocarbons has been evaluated using iron-enriched zeolite as heterogeneous catalyst. The electro-Fenton technology is an advanced oxidation process that is efficient for the degradation of organic pollutants, but it suffers from the high o...

Abstract A metal–organic framework (MOF) of cerium (Ce) ions and 4,4?,4??-nitrilotribenzoic acid linker was synthesized via a hydrothermal method. Ce-MOF consists Lewis moiety, i.e. Ce 3+ triphenylamine cores. It showed Fenton-like properties with excellent catalytic oxidation activity for olefins, primary/secondary alcohols, water pollutants e.g., organic dyes. displayed high conversion cinnam...

In this paper, we designed and synthesized free-metal dyes based on indoline. The proposed dyes were synthesized from phenothiazine as the starting material by standard reactions. The chemical structure of the synthesized dye was confirmed using FT-IR, 1HNMR and DSC techniques. Spectrophotometric measurements of the organic dyes in acetonitrile and on a TiO2 substrate ...

Abstract Environmental remediation of toxic organic pollutants on catalytic degradation has gained much attention. Organic dyes and fossil fuels as are the two major problems nowadays. The efficient targeted eradication dye from water systems is a critical global concern for treatment both drinking wastewater. In this study, ZnO–ZnS–CdO–CdS quaternary core–shell nanocomposites (NCs) were synthe...

Nowadays, materials with great potential for environmental protection are being sought. Metal–organic frameworks, in particular those cobalt species as active sites, have drawn considerable interest due to their excellent properties. This review focuses on describing cobalt-based MOFs the context of light-triggered processes, including dye degradation, water oxidation and splitting, carbon diox...

Phenols and their derivatives commonly exist in the environment. These compounds are used as the components of dyes, polymers, drugs and other organic substances. The presence of phenols in the ecosystems is also related with production and degradation of numerous pesticides and the generation of industrial and municipal sewages. Some phenols are also formed during natural processes. These comp...

the main theme to conduct present research work was to evaluate the effect of anaerobic granular sludge in degradation of two azo dyes. the study was evaluated in batch experiments where anaerobic and aerobic conditions were integrated by exposing anaerobic granular sludge to oxygen. under these conditions, the azo dyes were reduced, resulting in a temporal accumulation of aromatic amines. subs...

Porous silicon nanowires are synthesized through metal assisted wet-chemical etch of highly-doped silicon wafer. The resulted porous silicon nanowires exhibit a large surface area of 337 m(2)·g(-1) and a wide spectrum absorption across the entire ultraviolet, visible and near infrared regime. We further demonstrate that platinum nanoparticles can be loaded onto the surface of the porous silicon...
