摘要
Carbon materials have attracted much attention due to their high electrochemical catalytic activity, low cost, and excellent corrosion resistance against the redox couple.A simple and cost-effective method to prepare carbon materials from waste biomass was developed, and the structure, specific surface area, electrochemical catalytic activity and photovoltaic performance were investigated when the as-prepared carbon materials were applied as counter electrodes(CEs) materials in dye-sensitized solar cells(DSCs) and as accelerants in anaerobic digestion(AD).The power conversion efficiency of the DSCs using the as-prepared carbon materials achieved 5.24%-6.15%.The as-prepared carbon materials as accelerants in AD produce cumulative biogas yield of 380-500 mL/g TS, and COD degradation rate was more than 40% as compared with the control one.Those results indicated that the biomass-derived carbon has potential use in both areas of DSCs and AD.
