We report here the application of “preanodized” screen printed carbon electrode without the need of adding catalysts for the adsorption and subsequent oxidation of polyaromatic hydrocarbons (PAHs). By suitably defining the preanodization conditio

In this communication, we present some new findings on surface oxidized carbon nanotubes (CNTs) when used as cathode of Li–O2 batteries. It is found that the content of oxygen-containing functional groups has a significant influence on the electroc

Metal-oxygen systems are an attractive option to enhance the specific energy of secondary batteries. However, their power is limited by the oxygen electrode. In this communication we address the issue of the sluggish kinetics of the oxygen cathode in

In this paper we investigate in details the changes occurring in the lithium–oxygen cell during operation in a tetraglyme-base electrolyte, in terms of electrochemical behavior and of carbon electrode morphology. The study evidences a decrease of t

A facile, cost-effective and single-step pyrolysis approach using a single precursor is introduced to fabricate boron-doped carbon (BDC) without using a template, solvent, or catalyst. BDC has the ability to reduce oxygen directly to water with four

A straight-forward method for the synthesis of metal-free catalysts for oxygen reduction by thermal treatment of a mixture of poly(3,5-pyridine) with carbon black in helium is reported. The catalyst was characterized by X-ray diffraction and photoele

Cyanamide was used in the preparation series of metal–nitrogen–carbon (M–N–C) oxygen reduction catalysts. The best catalyst, treated at 1050 °C, shows good performance versus previously reported non-precious metal catalysts with an OCV ~1.0

The role of oxygen functionalities and edge plane sites on disposable screen-printed carbon electrodes (SPCE) was evaluated for simultaneous determination of dopamine, uric acid and ascorbic acid in this study. Both electrochemically preanodized and

A new electrocatalysis of carbon materials for oxygen reduction reaction (ORR) on Pt/C catalysts was discovered. It was found that there exist two kinds of electroactive sites on these supports of carbon materials, which can effectively electrocataly

The oxygen reduction reaction (ORR) has been studied on platinum free, palladium-based electrocatalysts in acid media. Polycrystalline electrodes were prepared by electrodeposition on a polycrystalline gold substrate using a dual ligand approach at r
