In situ dye sensitized solar cell driving E-Fenton oxidation system degradation of RhB based on P25/FTO and Fe@Fe2O3/ACFelectrodes
Recently electrochemical advanced oxidation technologies (EAOTs),involving an in situ generation of highly potent chemical oxidants such as hydroxyl radicals (·OH) with electric energy,has amused los of attention in degradation of aqueous recalcitrant organic pollutants due to its amenability to high efficiency,automation and environmental compatibility.Among EAOTs,photo-electrochemical oxidation (PEC) and electro-Fenton oxidation (EF) technologies are widely used for the destruction of recalcitrant organic contaminants that cannot be eliminated biologically in wastewater treatment.In this study we design an in situ dye sensitized solar cell driving E-Fenton oxidation system by coupling a P25/FTO anode with a Fe@Fe2O3/ACF composite cathode (P25/FTO | Fe@Fe2O3/ACF) in an undivided cell.This system could promote the separation of the holes and photoelectrons and meanwhile utilize the photoelectrons generated on the anode to reduce oxygen for the generation of H2O2 on the cathode.
