Abstract:

The electro–reduction of CeO2in eutectic CaCl2–NaCl melt was studied by cyclic voltammetry and constant voltage electrolysis techniques. One cathodic current peak in the cyclic voltammogram was observed and supports a one–step electro–reduction mechanism of CeO2. During different times of electrolysis at 800°Cof temperature and 3.0V of constant voltage, the products CeOCl and CeO2were observed by XRD and confirms the following electro–reduction sequence: CeO2CeOCl.

Abstract:

The treatment of metal-contaminated sediment generated in environmental dredging projects often requires both reduction and remediation, and the electric field has good application prospects in the integration of reduction and remediation. In this study, based on the electro-osmosis, vacuum, and vacuum electro-osmosis methods, a detachable test system was made. Experiments of the three methods were carried out independently on the reduction and remediation of dredged sediment from Tai Lake under pollution-free and Cu-contaminated conditions. The results show that copper contamination weakens t

Abstract:

The recycling of sodium borohydride poses a huge challenge to the drive towards a hydrogen economy. Currently, mechano-chemical, thermo-chemical and electrochemical are the only reported methods of recycling sodium metaborate into sodium borohydride. Much attention has been devoted to the mechano-chemical and thermo-chemical methods of reduction, but little focus has been devoted to electrochemical methods. This review describes the electrochemical behaviour of borohydride (BH4−) and metaborate (BO2−) anions in alkaline solutions. The BH4− is stabilized in highly concentrated alkaline solution

A comparative study of three kinds of electrolysis methods: indirect electro-oxidation, electro-flocculation and electro-Fenton, as pre-treatment processes for a real dyestuff wastewater with high salinity and unbiodegradable organics were investigated.

The results indicate electro-Fenton process as the most efficient pre-treatment method for improving biodegradability, reducing toxicity, and removing organic pollutants from dyestuff wastewater.

Abstract:

Carbon nano-onions (CNOs) were successfully synthesized by employing the flame pyrolysis (FP) method, using flaxseed oil as a carbon source. The alcohol reduction method was used to prepare Pd/CNOs and Pd-Sn/CNOs electro-catalysts, with ethylene glycol as the solvent and reduction agent. The metal-nanoparticles were supported on the CNO surface without adjusting the pH of the solution. High-resolution transmission electron microscopy (HRTEM) images reveal CNOs with concentric graphite ring morphology, and also PdSn nanoparticles supported on the CNOs. X-ray diffractometry (XRD) patterns confir

Abstract:

This paper deals with the advanced oxidation using Electro-fenton reagent for the degradation of azo-dyes in textile effluents. Discharge of textile effluents causes inevitable pollution of water resources which calls for further treatment methods. In this experiment, textile effluent samples were treated with iron electrodes with the reagents, hydrogen peroxide and ferrous sulfate .The acid dye effluents which were used in this study are Acid Orange 7, Acid Red 88, and Acid Violet 7. The temperature was set to 40° C. Samples of 20 ml were analyzed for Biological Oxygen Demand (BOD), Chemical

Abstract:

The reduction of Fe2O3-Al2O3 is one of the important reactions in the resource utilization of iron-containing oxide waste. Fe2O3-Al2O3 was electro-deoxidized in the NaCl-KCl system by molten salt electrolysis to prepare FeO/Al2O3. The effect of the Fe2O3 content on the electro-deoxidation reaction process was studied. The results show that under the conditions of 850 °C, 2.3 V, and electro-deoxidation for 4 h, FeO/Al2O3 could be obtained by controlling the content of Fe2O3. The deoxidation process was divided into three stages: electric double layer charging, Fe2O3 electro-deoxidation to Fe3O4

Abstract:

This work shows the preparation of carbon nanospheres with a high superficial nitrogen content (7 wt.%), obtained by a simple hydrothermal method, from pyrocatechol and formaldehyde, around which tungsten nanophases have been formed. One of these nanophases is tungsten carbide, whose electro-catalytic behavior in the ORR has been evaluated together with the presence of nitrogen surface groups. Both current and potential kinetic density values improve considerably with the presence of tungsten, despite the significant nitrogen loss detected during the carbonization treatment. However, the syner
