Summary: A novel binder-free AQS/PANI@CF cathode for selective H2O2 generation and efficient pollutant removal in electro-Fenton was fabricated, showing high stability and repeatability. The cathode achieved a high H2O2 concentration of 83.3 mu mol L-1 and a RhB degradation efficiency of 98.8% within 60 minutes. The main generated reactive radicals were identified through quenching experiments and EPR tests, and a plausible mechanism of the cathode applied electro-Fenton process was proposed. This work serves as a reliable reference for subsequent investigations.

Summary: We report on the formation and enhanced electrochemical capacitive behavior of semi-polycrystalline polyaniline synthesized by a modified surfactant-free chemical route. The material exhibits spindle-shaped morphology and well-defined crystallographic lattices. Characteristic chemical properties of polyaniline are recorded using Fourier transform infrared technology and laser Raman spectroscopies. The material shows features of surface-redox pseudocapacitance in cyclic voltammetry curves. With a scan rate of 10 mV s(-1), the specific capacitance of the material is calculated to be 551 F g(-1). Good stability is observed in cycle stability and coulombic efficiency over 3000 cycles at a current density of 12 A g(-1) (90.3% and 99.5%, respectively).

Summary: Bio-electrochemical systems (BESs) have gained attention in wastewater treatment due to their fast electron transfer rate and high performance. However, the low electro-chemical activity of commonly used carbonaceous materials in BESs limits their practical applications, especially for refractory pollutants remediation. In this study, a reduced graphene oxide (rGO) and polyaniline (PANI) modified electrode with improved electro-chemical activity was fabricated using carbon brush as raw material. The rGO/PANI electrode showed highly conductive network with increased electro-active surface area and decreased charge transfer resistance, leading to highly efficient azo dye removal from wastewater. This research provides new insights for the development of high performance BESs through electrode modification.
