“…5 reveals that, the pH that yields the major oxidation of phenol via a photoFenton process is 2.8, under the current experimental conditions and range of pH studied. In fact, it is known that Fenton processes are more efficient at pH close to 3 because the oxidation potential of the hydroxyl radical adopts its highest value (2.80 V) [25]. The profile of disappearance of phenol shown in Fig.…”

“…This is clearly related to the stability of H 2 O 2 which is strongly affected by pH. In Fenton chemistry, it is generally accepted that iron hydroxide can be formed at a pH above 4, which is not favorable for the generation of hydroxyl radical species . A lower pH is favorable for stabilizing H 2 O 2 but the formation of H 3 O 2 + , which occurs at a pH below 2, is not desirable for the formation of reactive hydroxyl radical species .…”

Direct conversion of methane into value‐added chemicals is a challenging but worthwhile subject. In this communication, the direct conversion of methane into methane oxygenates was achieved in an aqueous solution at room temperature using iron salts and Pd/C as catalysts and hydrogen peroxide as an oxidant. The hydrogen peroxide can be directly added or generated in situ from hydrogen and oxygen. The Pd/C catalyst greatly enhanced the reaction rate together with the iron salts. The effect of some parameters such as reaction temperature, reaction time, pH, acid type, and catalyst amount on the yields of the methane oxygenates was also investigated. When hydrogen peroxide was directly added, the turnover frequency (TOF), defined as the moles of methane oxygenates per moles of Fe per unit time, at 293 K was 29 h−1 at pH=2.3. The TOF at 293 K was 42 h−1 at pH=1.3 with in situ generated hydrogen peroxide from hydrogen and oxygen.

Abstract:The basic and applied aspects of Fenton and Fenton-like processes for removal of pollutants using zerovalent iron materials, including nanoparticles, are reviewed in this article. Only those examples including the use of the iron materials together with hydrogen peroxide addition are included. The mechanistic aspects of homogeneous and heterogeneous Fenton processes, still under discussion, are displayed. The use of biogenic generated iron nanoparticles for removal of pollutants is discussed due to their novelty and economy of synthesis.
