Claim 1:
2. The method for preparing lignin porous carbon nanosheets according to claim 1, wherein being “assembled” means the lignin/oxalate composite is added to the matrix solution and stirred uniformly, and then ethanol is added thereto for precipitation and separation to obtain the assembled lignin/oxalate composite;
being assembled “multiple times” means repeating the above assembly steps many times; specifically, the assembled lignin/oxalate composite is added to the matrix solution and stirred uniformly, and then ethanol is added thereto for precipitation and separation to obtain the lignin/oxalate composite after the secondary assembly, with the process repeated 6-10 times.
