The electrochemical reduction of CO2 on planar electrodes is limited by its prohibitively low diffusivity and solubility in water. Gas-diffusion (GDEs) can be used to reduce these limitations, facilitate current densities orders magnitude higher than the limiting electrodes. These improvements are accompanied increased variation local environment within cathode, with significant effect Faradaic...

Tetrathiafulvalene (TTF) exhibits two reversible oxidation steps and is used as a novel multi-electron catholyte for nonaqueous organic redox flow batteries. To increase solubility in polar solvents, TTF derivatives with side chains are synthesized. 4-Methoxymethyl tetrathiafulvalene emerges promising two-electron because it liquid at room temperature miscible acetonitrile. Bulk-electrolysis ex...

This paper focuses on changes in potential drops over different parts of a two-compartment electrodialtyic cell during process developed for P recovery from sewage sludge ash and simultaneous removal heavy metals. The has two compartments separated by cation exchange membrane. suspension is the anode compartment. major aim this work to obtain knowledge needed optimize energy consumption process...

In this study, the electrochemical impedance characteristics of CO2/H2O co-reduction to produce CO/H2 syngas were investigated in a low-temperature single cell. The effect operating conditions on single-cell performance was evaluated at different feed concentrations and cell voltages, corresponding spectroscopy (EIS) data collected analyzed. Nyquist plots exhibited two semicircles with separate...

Azobenzene (azoB) is a promising anode active material for nonaqueous redox flow battery (NARFB), but the performance assembled with azoB rather poor. Here, we show that rate of NARFB and 2,5-di-tert-butyl-1-methoxy-4-[2?-methoxyethoxy] benzene (DBMMB) as anolyte catholyte materials can be significantly enhanced by optimizing solvent, supporting electrolyte, membrane. The synergistic interactio...
