摘      要：An anodic TiO2/g-C3N4 hetero-junction and cathodic WO3/W were used to build a self-sustained catalytic fuel cell system for oxidizing rhodamine B or triclosan and reducing NO3^--N to N2 *** WO3 nano-catalyst was formed in situ by heating and oxidizing a tungsten wire in *** voltammetry and current-time curves were used to characterize the electrochemical properties of the electrodes and *** and activation of molecular oxygen by self-biased TiO2/g-C3N4 led to the formation of reactive oxidizing species in the fuel *** mechanism of simultaneous anodic oxidation of pollutants and cathodic reduction of nitrate was *** spontaneously formed circuit and tiny current were used simultaneously in treating two kinds of wastewater in the reactor chambers,even without light illumination or an external applied *** new catalytic pollution control route can lower energy consumption and degrade many other kinds of pollutants.
