Aqueous CO2-to-CO electrolysis is a promising technology for closing the carbon cycle and defossilizing industrial processes. Considering technological readiness, consensus has been achieved about using silver as stable selective electrocatalyst reduction reaction in aqueous electrolyte. On other hand, challenges such media flow management, component stability, force distribution are still asso...

BACKGROUND This work studied the treatment of and metal recovery from a synthetic acid mine drainage (AMD) containing 500 mg L−1 copper (Cu2+) iron (Fe+3), 50 nickel (Ni2+) tin (Sn2+) by using bioelectrochemical system (BES). The presence electroactive bacteria improved performance such reactor configuration, contrast with systems abiotic anodes. RESULTS Operating as microbial fuel cell (MFC), ...

Powder extrusion molding is proposed to fabricate ceramic LiFePO4 layers (0.5–1.0 mm thickness) as solid booster for ferricyanide electrolyte in semisolid redox flow battery. In some extruded layers, the binder partially decomposed, while others it completely removed and, afterwards, material sintered, so materials with different porosity and dimensions are obtained. After characterizing materi...

Microbial community changes in response to acid stress microbial fuel cells (MFCs) were studied. Acid mine drainage (AMD) wastewater is usually difficult treat because of the high concentration sulfate and heavy metals. MFCs, which have multiple functions based on principle synergistically treating organic metal while generating electrical energy, represent a promising direction for development...

ConspectusFlow battery (FB) is nowadays one of the most suited energy storage technologies for large-scale stationary storage, which plays a vital role in accelerating wide deployment renewable energies. FBs achieve conversion by reversible redox reactions flowing active species at positive and negative sides. An ion conducting membrane (ICM) necessary to separate anolyte catholyte, while charg...

The atmospheric corrosion of Mg and MgAl alloys was investigated. Corrosion tests were performed in the laboratory under controlled environment. CP Mg, AM50 and AZ91 samples were exposed at 95% RH and 22°C in the presence and in the absence of 400 ppm CO2 for 24 h to 672 h. The passive film was characterized by means of XPS, FTIR, AES and XRD. The film consisted of MgO/Mg(OH)2 with carbonate on...

HYDROGEN interaction with amorphous alloys has Ribbons (,25-mm thick) of amorphous Fe80B11Si9 were been studied extensively due to both scientific and technoused for this research. The ribbons were produced by planarlogical interest. In the framework of a more comprehensive flow casting and were kindly supplied by AlliedSignal Inc. investigation of hydrogen interaction with amorphous and (Parsi...

The possibility of using molten mixtures of 1,4-dimethyl-l,2,4-triazolium chloride (DMTC) and aluminum chloride (A1C13) as secondary battery electrolytes was studied, in some cases extended by the copresence of sodium chloride. DMTC-A1CI~ mixtures demonstrated high specific conductivity in a wide temperature range. The equimolar system is most conductive and has K values between 4.02 x 10 -~ an...
