A simple method for preparing 3D hierarchical carbide derived carbon by single step molten salts electrolysis

摘要

In this work, we have proposed a simple, cost-effective and green method for the production of 3D hierarchical carbide derived carbon by single step molten salts electrolysis at 710 degrees C. During the electrolysis process, the high carbon ferromanganese fed manganese and iron ions into molten salts and then those ions were reduced on cathode. At last, there is only porous left on the anode. By XRD and Raman analysis, it was found that the as-prepared porous carbon is composed of amorphous carbon and ordered graphitic carbon with a high degree of graphitization. SEM, TEM and N-2 sorption measurement indicate that this type of CDC has a multimodal pore system consisting of micro-pores, meso-pores and macro-pores.
