Original Data for Development of Pd-Ni/Ni foam cathode based MFC-PMS system for dye wastewater treatment: Performance and underlying mechanism
Description
This dataset contains the original experimental data supporting the research article on the development of a novel Pd-Ni/Ni foam cathode for microbial fuel cell-peroxymonosulfate (MFC-PMS) system for dye wastewater treatment. The data includes: Electrochemical Performance Data: Polarization curves and power density measurements for three different electrodes: Carbon cloth, Ni foam, and Pd-Ni foam Voltage monitoring data over extended operation periods Current-voltage characteristics under varying conditions Material Characterization Data: SEM images showing the microstructural evolution of electrode materials EDS spectra and elemental composition analysis (including weight% and atomic% quantification) XRD patterns for crystal structure identification BET surface area measurements Microbial Analysis Data: 16S rRNA sequencing data showing microbial community composition Relative abundance of key electroactive bacteria (Geobacter, Thiobacillus, etc.) Functional gene expression profiles related to electron transfer mechanisms Wastewater Treatment Performance: Dye degradation efficiency under different operational conditions Chemical oxygen demand (COD) removal data PMS activation efficiency measurements Reactive oxygen species quantification Experimental Parameters: Detailed operational conditions (pH, temperature, PMS concentration, etc.) Electrode preparation protocols Analytical methods and instrumentation specifications
