Cu-Ni nanostructured electrocatalysts obtained by electrocodeposition
Environmental Engineering and Management Journal › Vol. 8 › Nr. 4 Abstract
A simple method to synthesize copper, nickel and Cu-Ni nanotubes in alumina membrane by direct electrochemical deposition technique is presented.
This work is divided into three main parts:
- elaboration of the nanostructured metals supported on Cu and Ni electroconductive support;
- SEM - EDX characterization of nanodeposits;
- electrochemical characterization of the nanostructured electrodes;
Cu and Cu-Ni nanostructures were obtained by deposition through an alumina membrane (... Autori: Maria Jitaru, Ana-Maria Toma, Mihaela-Claudia Tertis, Ancuta Trifoi ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=25496
BORON-DOPED DIAMOND ELECTRODE-BASED ADVANCED TREATMENT METHODS FOR DRINKING WATER
Environmental Engineering and Management Journal › Vol. 13 › Nr. 9 AbstractIn this study, boron-doped diamond (BDD) electrode was tested in electrochemical oxidation and reduction processes using thesame vertical electrodes undivided cell in order to remove natural organic matter (NOM) and nitrogen compounds (NC) fromdrinking water. Boron-doped diamond-based electrochemical oxidation process has proven to be an efficient and versatilemethod suitable for NOM and NC in forms of nitrite and ammonium present in drinking water sources. However, the applicationof BDD... Autori: Florica Manea ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26492
A PRELIMINARY STUDY ON ELECTROCATALYTIC CONVERSION OF CO2 INTO FUELS
Environmental Engineering and Management Journal › Vol. 13 › Nr. 10 AbstractThe CO2 electroreduction in gas phase using Pt on carbon black catalysts is investigated in this work. This process is expected tobecome a key technology to prevent anthropogenic CO2 emissions. Specifically, the electrocatalytic reduction in a solventless gasphase is studied, as a first approach to later develop a photoelectrocatalytic device for the efficient conversion of CO2 to fuelsusing solar energy for the reaction. The objective of this preliminary work has been the tuning up of t... Autori: Fabiola Martínez ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26578
IRON ELECTROCOAGULATION WITH ENHANCED CATHODIC REDUCTION FOR THE REMOVAL OF AQUEOUS CONTAMINANT MIXTURES
Environmental Engineering and Management Journal › Vol. 14 › Nr. 12 Abstract
This study presents enhanced reduction of soluble contaminants in a modified electrocoagulation process that is capable of
treating a mixture of aqueous contaminants. By incorporating an iron foam cathode, the process can remove aqueous
trichloroethylene (TCE) by 99.1% and nitrate ions by 98.2%, which represents 58.1 and 20 percent higher than the removal rates
achieved by iron plate cathode, respectively. pH and ORP measurements indicate the development of a reducing electrolyte
