| 英文摘要 | Microbial fuel cells (MFCs) are attractive due to the inherent potential for effective clean energy extraction from wastewater. Unfortunately, it is still a challenge to achieve high power by improving the extracellular electron transfer (EET) efficiency between the bacteria and the electrode. Herein, a three-dimensional (3D) macroporous sugarcane carbon (SC) embedded with Fe nanoparticles (20-40 nm) with graphite protective layers (3D nano-Fe@C/SC) is prepared for the MFC anode. The 3D nano-Fe@C/SC anode with low charge transfer resistance (0.38 Omega) facilitates microbial adhesion/colonization, achieving a superior power density of 3012.7 mW m(-2) in acetate-feeding MFC, which is higher than that of previously reported studies dealing with biochar-based anodes. The 3D nano-Fe@C/SC anode also exhibits a higher Cr(VI) removal efficiency (91 %) than that of SC (63 %) or carbon cloth (CC) (16 %) anodes under neutral conditions (pH 6.7). This high-performance anode material can promote pollutant removal and energy conversion, which will have promising applications in sustainable wastewater treatment via MFCs. |
