High selectivity of benzene electrochemical oxidation to p-benzoquinone on modified PbO2 electrode

Intrinsic Iron‐Containing Multiwalled Carbon Nanotubes as Electro‐Fenton Catalyst for the Conversion of Benzene to Redox‐Active Surface‐Confined Quinones

“…It is speculated that the 2.1 wt % iron impurity in pristine MWCNT‐Fe* involved in the electrochemical oxidation is similar to the iron oxide and was immobilized ex situ onto the solid electrode system for the BZ oxidation with H 2 O 2 through an electro‐Fenton‐type reaction mechanism ,,. It is likely that BZ can be electro‐oxidized to quinone‐like compounds, such as hydroquinone (HQ) and/or catechol (CA), designated as BZO, on the MWCNT‐Fe* surface, which might result in the specific redox peaks in the CV response (Figure C, curve b). Hereafter, the BZ electro‐oxidized GCE/MWCNT‐Fe* system is designated as GCE/MWCNT‐Fe*@BZO.…”

Minimizing the Health Risks from Hydrocarbon Contaminated Soils by Using Electric Field-Based Treatment for Soil Remediation

“…A current promotes the movement of pollutants in the pore fluid towards the electrode chambers, where they are finally collected and treated. Therefore, this technique is recommended for application with fine and low-permeability soils [24][25][26][27] and has been mainly applied to the treatment of soils polluted by metals, due to the property to move the ionic species [28]. This treatment has emerged as an alternative to conventional soil treatments due to its peculiar advantages, namely the capability of treating fine and low-permeability materials, as well as achieving a high yield in the removal of salt content and inorganic and organic pollutants [29].…”

Study on the properties of Pb–Co3O4–PbO2 composite inert anodes prepared by vacuum hot pressing technique

“…8 In order to solve the above problems, there are two main optimization routes by researchers. [9][10][11][12][13][14] (i) The electrocatalytic activity, corrosion resistance and mechanical properties are improved by binary alloy and multi-component alloy base on Pb substrate such as Pb-Ag, Pb-Sn, Pb-Ca, Pb-Ba, Pb-Cd, Pb-Ag-Ca, Pb-Ag-Ti and Pb-Ag-Sn. [15][16][17][18] But there are still some defects such as high energy consumption and short service life.…”
