The decaheme cytochrome MtrC from Shewanella oneidensis MR-1 immobilized on an ITO electrode displays unprecedented H2O2 reduction activity. Although MtrC showed lower peroxidase activity in solution compared to horseradish peroxidase, the ten heme cofactors enable excellent electronic communication and a superior activity on the electrode surface. A hierarchical ITO electrode enabled optimal i...

Multi-walled carbon nanotubes (MWCNTs) were synthesized on platinum plate electrodes by the chemical vapor deposition (CVD) method. From the results of X-ray photoelectron spectroscopy and voltammetric investigation, the iron nanoparticles used as a catalyst for the MWCNT synthesis were enclosed with MWCNTs. The MWCNTs synthesized on the Pt plate (MWCNTs/Pt) electrode were immediately immersed ...

The oxidation of a pure pyrite by Thiobacillus ferrooxidans is not really a constant phenomenon; it must be considered to be more like a succession of different steps which need characterization. Electrochemical studies using a combination of a platinum electrode and a specific pyrite electrode (packed-ground-pyrite electrode) revealed four steps in the bioleaching process. Each step can be ide...

Abstract The oxygen evolution reaction (OER) and the value‐added oxidation of renewable organic substrates are critical to supply electrons protons for synthesis sustainable fuels. To meet industrial requirements, new methods a simple, fast, environmental‐friendly cheap robust, self‐supported high surface area electrodes required. Herein, novel in‐liquid plasma (plasma electrolysis) approach gr...

Oxygen Evolution Reaction For green hydrogen production, the development of highly active and durable electrode materials that function under intermittent power supply renewable energies is necessary. In article number 2204403, Byung-Hyun Kim, MinJoong Hyun-Seok Cho, co-workers propose rational design a stable iron-rich nickel-iron layered double hydroxide dynamic operating conditions for alkal...

In this study, a symmetric supercapacitor has been fabricated by adopting the nanostructured iron oxide (Fe3O4)-activated carbon (AC) composite as the core electrode materials. The composite electrodes were prepared via a facile mechanical mixing process and PTFE polymeric solution has been used as the electrode material binder. Structural analysis of the nanocomposite electrodes were character...

Iron-based electrode materials are widely investigated for robust and high-performance SOCs because of their low-cost the appropriate valence stability Fe–O bond to exhibit excellent redox activity across a wide range functions.
