PROGRESS REPORT Microbial Electrosynthesis www.advmat.de Dual-Function Electrocatalytic and Macroporous Hollow-Fiber Cathode for Converting Waste Streams to Valuable Resources Using Microbial Electrochemical Systems Krishna P. Katuri, Shafeer Kalathil, Ala’a Ragab, Bin Bian, Manal F. Alqahtani, Deepak Pant, and Pascal E. Saikaly* increased resource (water, energy, food, Dual-function electrocatalytic and macroporous hollow-fiber cathodes and chemicals) consumption with con- are recently proposed as promising advanced material for maximizing comitant production of large volumes of the conversion of waste streams such as wastewater and waste CO2 to “used resources,” commonly recognized as waste. These “used resources” could valuable resources (e.g., clean freshwater, energy, value-added chemicals) potentially represent an economic value if in microbial electrochemical systems. The first part of this progress report they are recovered. There is an emerging reviews recent developments in this type of cathode architecture for the interest worldwide for resource recovery simultaneous recovery of clean freshwater and energy from wastewater. from waste streams
