Microbial fuel cells (MFCs) are promising bioelectrochemical systems for simultaneous wastewater treatment and electricity generation, but their performance is strongly influenced by electrode properties. Carbon cloth (CC) is attractive as an electrode support because of its conductivity, chemical stability, and accessible surface structure. In this preliminary study, graphene oxide (GO) was applied to the anode and reduced graphene oxide/carbon nanotube (rGO/CNT) composites were investigated as cathode coating materials. The coating mass was evaluated gravimetrically after the coating process. Based on the supplied experimental chart, the GO-coated anode showed a coating mass of 0.005 g, whereas rGO/CNT cathodes with ratios of 1:0, 1:1, 1:2, and 1:3 showed coating masses of 0.001, 0.003, 0.003, and 0.002 g, respectively. The highest cathode coating mass was obtained at rGO:CNT ratios of 1:1 and 1:2. Compared with rGO alone (1:0), these formulations produced a threefold coating mass. The results indicate that rGO:CNT composition affects the amount of material retained on the carbon cloth surface and provides a useful screening parameter before electrochemical evaluation. However, coating mass alone cannot establish the optimum electrode composition; electrical conductivity, electrochemical surface area, adhesion stability, polarization behavior, and MFC power output should be evaluated in subsequent experiments.
