摘要

摘要: 吸附和电解是2种去除水中有机物的有效方法，为发挥吸附和电解对有机物的协同作用，将具有优良吸附导电性能的还原氧化石墨烯（RGO）与活性炭（AC）复合得到复合材料并将其黏附在Ti极片上，得到RGO/AC/Ti复合电极用于电解水中的甲基橙。利用SEM、FT-IR、BET、XRD、C-V、EIS等对复合材料及电极进行表征，考察了Ti、RGO/Ti和RGO/AC/Ti对甲基橙的电化学性能。结果表明：与RGO相比，RGO/AC的比表面积由318.1 m²/g增加到405.1 m²/g。相对于RGO/Ti，RGO/AC/Ti电极比电容值略有下降，但电容保持率提升。在电解质浓度为0.15 mol/L，极距为15 mm，电流为100 mA，pH为6时，Ti、RGO/Ti和RGO/AC/Ti电极对甲基橙的去除率分别达到48.1%、79.5%和88.8%，去除效果较好。

Abstract: Adsorption and electrolysis are two effective methods to remove organics in water. In order to exert the synergistic effect of adsorption and electrolysis on organics, graphene oxide (RGO) with excellent adsorption conductivity and activated carbon (AC) were compounded to obtain composite materials, which were adhered to Ti electrode plate to obtain RGO/AC/Ti composite electrode for the electrolysis of methyl orange in water. The composite and electrode were characterized by SEM, FT-IR, BET, XRD, C-V and EIS. The electrochemical properties of Ti, RGO/Ti and RGO/AC/Ti for methyl orange were investigated. Compared with RGO, the specific surface area of RGO/AC increased from 318.1 m²/g to 405.1 m²/g. Compared with RGO/Ti, the specific capacitance of RGO/AC/Ti electrode decreased slightly, but the capacitance retention increased. When the electrolyte concentration was 0.15 mol/L, the electrode distance was 15 mm, the current was 100 mA and the pH was 6, the removal rates of methyl orange by Ti, RGO/Ti and RGO/AC/Ti electrodes were 48.1%, 79.5% and 88.8%, respectively. Then satisfactory removal effect was obtained. The paper provided a new idea for the treatment of refractory organic wastewater such as dyes.
