In this report, boron doped mesoporous activated carbon (B-MAC) was synthesized by direct hydrothermal route. The prepared B-MAC was characterized for HR-TEM, wide-angle XRD, SEM, XPS, FTIR and N-2 sorption analyses. The results suggested that the B-MAC is mesoporous in structure and amorphous in nature, with surface area of 3.036 m(2) g(-1). The B-MAC was chosen as a catalyst for the electrochemical oxidation of synthetic aniline solution. For the oxidations process, graphite rod was chosen as anode; SS 316 was chosen as cathode in the electrochemical catalytic oxidation process. The electro chemical oxidation of aqueous aniline solution was confirmed through UV-visible spectroscopy, Florescence emission spectrum and cyclic voltammetry analyses. The results revealed that, the removal efficiency of COD and aniline by B-MAC was found to be 76-80% and 80-85%, respectively, in electro catalytic oxidation. MAC fluidized electro catalytic oxidation system removed COD by 40-45% and aniline by 50-62%, respectively. Thus, the B-MAC catalyst was found to be viable for the electrochemical treatment of aniline containing waste water. (C) 2014 The Korean Society of Industrial and Engineering Chemistry.
