A Review on Nano

2020/5/30Electrochemical partial exfoliation of graphitic materials is the most common synthesis method of electrochemically synthesizing 3D carbon materials. As indicated by its name, electrochemical partial exfoliation only partially exfoliates graphitic precursors, e.g., carbon fibers [ 37, 85, 97, 99 ], graphene aerogels [ 99 ], and graphite foils [ 88, 103, 104 ], leading to graphene
