Electrochemical Oxygen Reduction for the Production of Hydrogen Peroxide
The development of economical, stable, and highly active electrocatalysts for the oxygen reduction reaction (ORR) to form water represents a major thrust in the research area of polymerelectrolyte-membrane fuel cells. However, one of the main challenges facing these low-temperature fuel cells is slow ORR kinetics at the cathode, even with the use of Pt-based catalysts. In addition, Pt-based cat...
متن کاملA printed electrocatalyst for hydrogen peroxide reduction
The modification of silver screen-printed electrodes with a dodecyl benzenesulphonic acid and KCl solution was performed by inkjet printing. Scanning Electron Microscopy was performed to characterize the electrode surfaces. Electrochemical reduction of H2O2 was studied and compared to electrodes modified by dip-coating. Analytical parameters of the allprinted electrode such as LOD, sensitivity ...
متن کاملGreen oxidation with aqueous hydrogen peroxide.
Aqueous H2O2 is an ideal oxidant, when coupled with a tungstate complex and a quaternary ammonium hydrogensulfate as an acidic phase-transfer catalyst. It oxidizes alcohols, olefins, and sulfides under organic solvent- and halide-free conditions in an economically, technically, and environmentally satisfying manner.
متن کاملOptical Analyzer for Continuous Monitoring of Dissolved Oxygen in Aviation Fuel and Other Non-aqueous Media
A special sensitive element based on the novel composite material was created. The sensor has a linear calibration and is resistant to aliphatic hydrocarbons, in particular aviation fuel. A low cost and easy-to-implement method for calibrating the sensor was proposed. Temperature dependence of the oxygen mass transfer coefficient kL was measured for aviation fuel TS-1 (Russi...
متن کاملNox4: A Hydrogen Peroxide-Generating Oxygen Sensor
Nox4 is an oddity among members of the Nox family of NADPH oxidases [seven isoenzymes that generate reactive oxygen species (ROS) from molecular oxygen] in that it is constitutively active. All other Nox enzymes except for Nox4 require upstream activators, either calcium or organizer/activator subunits (p47(phox), NOXO1/p67(phox), and NOXA1). Nox4 may also be unusual as it reportedly releases h...
