Photo-Electrochemical Technologies for Removing Organic Compounds in Wastewater
Abstract In recent years, electrochemical technologies for the prevention and remediation of environmental pollution have been strongly developed. A review of photoelelectrocatalysis (PEC) for the treatment of wastewater is presented in this chapter. Different types of photo-anodes and cathodes have been developed and studied to increase the efficiency of PEC for the removal of organic compounds. An interesting parameter that was investigated in the last work is the generation of an active species by the utilization of proper cathodes. Moreover, this chapter deals with the keys factors affecting the PEC, including electrolyte oxidation.
Design of highly efficient porous carbon foam cathode for electro-Fenton degradation of antimicrobial sulfanilamide
Abstract This work investigated, for the first time, the potential of novel biomass derived carbon foam as a suitable and efficient electrocatalytic material (as cathode) for in-situ hydrogen peroxide (H2O2) production and its applicability in electro-Fenton (EF) approach for oxidizing organic pollutants. The carbon foam cathode was prepared by polymerization and carbonization of sucrose at high temperature. The as-prepared carbon foam consists of highly porous and extremely light structure with interconnected spherical cells. It exhibited excellent electrocatalytic properties such as high conductivity, relatively high redox current and several active-sites for producing oxidizing species, …
Diamond Films as Support for Electrochemical Systems for Energy Conversion and Storage
Many efforts have been dedicated to develop and study different catalysts supported materials for energy storage and conversion. Polymer electrolyte membranes (PEM) and capacitors have been topics of special interest for the scientific community, then, the research to find excellent catalyst-supports has constantly increased. The use of conductive diamond films has been proposed due to their mechanical and chemical stability properties. In this context, the application of BDD-catalyst surfaces for PEM fuel cells as well as the production of electrochemical capacitors using BDD materials have been summarized and discussed in this chapter.
Electrochemical technology for the treatment of real washing machine effluent at pre-pilot plant scale by using active and non-active anodes
Abstract Real effluent of washing machine is one of the major sources of microplastics and fabrics in municipal and surface water. The effluents constitute large volume of wastewater with different surfactants since every household and industries nowadays use washing machine rather than traditional hand washing. In this work, a real effluent of washing machine was treated by electrooxidation (EO) in a pre-pilot plant scale electrochemical flow reactor using active (Ti/Pt) or non-active (boron doped diamond (BDD)) anodes and Ti cathode. The effect of anode material (Ti/Pt or BDD) and the applied current density (16.6, 33.3 and 66.6 mA cm−2) on the decay of the organic matter, in terms of che…
