The molybdenum disulfide (MoS2) was loaded on the stainless steel fiber felt (SSFF) by hydrothermal synthesis method to prepare SSFF-MoS2 in this study. The effects of (NH4)6Mo7O24·4H2O concentration, molybdenum-sulfur atomic ratio, reaction time and reaction temperature on the electrochemical performance of SSFF-MoS2 were investigated. Scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), fully automatic specific surface, porosity analyzer (BET), Fourier transform infrared spectrometer (FT-IR), X-ray powder diffractometer (XRD), and X-ray photoelectron spectroscopy (XPS) were physically characterized to reveal the differences between SSFF-CK and SSFF-MoS2 prepared under optimal conditions. The results show that SSFF-MoS2 prepared at a reactant concentration of 0.005 mol/L, a molybdenum-sulfur atomic ratio of 1∶4, a reaction time of 24 h and a reaction temperature of 180 ℃ had a stronger current response, lower internal resistance and higher exchange current density. The physical characterization results show that MoS2 was successfully loaded on the surface of SSFF, and the specific surface area of the SSFF-MoS2 composite prepared under optimal conditions was 2.14 times that of SSFF-CK. This study is expected to use SSFF-MoS2 as cathode for microbial fuel cells (MFCs) to improve the cathode performance. ? 2023 Journal of Functional Materials.
