“…1(b). FTIR curves also show C-H deformation vibration at 1443 cm -1 while the strong transmission from 900 cm -1 to 600 cm -1 could be signed as fingerprint region of C-H on aromatic ring 26,27 . S1), suggesting ZnCl 2 as active agent hasn't changed the basic crystallinity of the samples.…”

Graphical AbstractPorous carbons were prepared from enteromorpha overrunning in China Sea with ZnCl 2 as active reagent. The prepared porous carbon with a specific surface area of 1651 m 2 /g exhibited a specific capacitance of 206 F/g and capacity retention of 93% even after 5000 cycles, indicating good electrochemical properties and promising utilization future of enteromorpha as electrode materials for supercapacitors.Porous carbons were prepared from enteromorpha overrunning in China Sea with ZnCl 2 as active agent. The obtained porous carbons were used as electrode materials to make supercapacitors. In order to make enteromorpha based supercapacitors with high performance, the effects of preparation parameters including impregnation weight ratio of ZnCl 2 to enteromorpha, activation time and temperature on pore structure and electrochemical performances of enteromorpha based porous carbons (EBPCs) were investigated. The specific area and porous structure were characterized by nitrogen adsorption. Galvanostatic charge-discharge and cyclic voltammetry analysis were used to investigate the electrochemical properties of EBPCs. The results show that activation temperature of 700 °C, the impregnation weight ratio of 2/1 and activation time of 1.5 h are the optimal preparation parameters. The prepared EBPC with a specific surface area of 1651 m 2 /g exhibited a specific capacitance of 206 F/g and capacity retention of 93 % even after 5000 cycles, showing excellent electrochemical properties of EBPC and good utilization future of enteromorpha. the pseudocapacitance contribution is little, and specific capacitance derives mainly from electric double layer capacitance 34 . In addition, the CV curve of H700-0-1.5 has a larger area than those of H800-0-1.5 and H600-0-1.5, indicating the highest specific capacitance, which can also be confirmed by galvanostatic charge-discharge curves in Fig. 7(a).

“…The increase of basal spacing of GO in the course of oxidation owing to the expansion of the layer planes caused by accommodation of various oxygen species and the changes of carbon hexahedron grid plane during oxidation [47]. The interlayer spacing of GO (0.858 nm) was in the range of the reported values (0.6-1.1 nm) [48]. The weak peak at 2Â = 20.6 • indicated the existence of some stacking structures.…”

“…According to XPS data, oxygen content in samples 2 and 3 is about 20%, which is a little higher than the value by elemental analysis. The heterogeneous characteristic with extensive functionalisation on the surface and none or less in the bulk accounts for the error between two analytical results [9]. The O/C ratios of both two samples are about 0.19.…”
