Zero-valent iron supported on nitrogen-containing activated carbon for catalytic wet peroxide oxidation of phenol

Nitrogen-doped carbon nanomaterials: To the mechanism of growth, electrical conductivity and application in catalysis

“…The use of such bifunctional supports provided a substantial increase in the activity of a palladium catalyst for the liquid-phase oxidation of benzyl alcohol to benzaldehyde [119] or an iron metal catalyst for the oxidation of phenol by hydrogen peroxide [120] in comparison with unmodified supports.…”

Efficient Removal of Methylene Blue by Fenton-like Reaction using nZVI/GAC Composite as Catalyst

“…Nano-zero valent iron (nZVI) is currently of an interest catalyst to decompose hydrogen peroxide (H 2 O 2 ) to produce hydroxyl radicals (·OH) owing to its high surface and activity in Fenton-like system. However, nZVI is tend to aggregate because of its small size, which decreases the surface area of nZVI and hinders the regeneration of ferrous ions (Fe 2+ ), often resulting in the decrease of catalytic degradation efficiency [2]. Thus, it is necessary to modify the features of nZVI.…”

Preparation of Novel Fe Catalysts from Industrial By-Products: Catalytic Wet Peroxide Oxidation of Bisphenol A

“…Carbonaceous materials are known to contain metal impurities such as iron and their presence may increase the catalytic activity [51]. Also, the impregnated iron has been shown to enhance the catalytic oxidation of various compounds using carbon-based catalyst in CWPO in several works [35,52,53,54,55,56].Therefore iron was chosen as an active metal for the CR support.…”

“…CWPO was adapted from a classical Fenton process [32], which has been referred to as an economical alternative to wastewater treatment techniques [33] because it requires only basic equipment and operates at ambient-like pressure and temperature [34,35]. During this process, hydrogen peroxide (H O ) decomposes in the presence of the catalyst (typically Fe or Cu salts) producing highly reactive hydroxyl radical species (OH ) that degrade most of the organic pollutants present in the wastewater [36].…”
