Phosphorus-Doped Exfoliated Graphene for Supercapacitor Electrodes

Abstract

Graphene, a single atom thick carbon material with high surface area and electrical conductivity provides an ideal platform for designing high performance electrochemical devices. This paper reports the synthesis of phosphorous doped graphene from reduced graphene sheets, its characterization by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy and its use for supercapacitor applications. The specific capacitance was found to be 367 Fg(-1) from electrochemical measurements. These samples show a high power density of 9 kW kg(-1) and energy density of 59 Wh kg(-1) in an aqueous electrolyte solution, which is much higher than other graphene-based supercapacitors. The phosphorus-doped graphene showed a high potential for use in low cost energy storage devices.

A first-principles study of light non-metallic atom substituted blue phosphorene

“…Doped 2D materials are, therefore, useful for various applications including energy storage [4][5][6][7][8], energy conversion [9,10], and sensing [11][12][13][14]. Also, there are abundant works [15][16][17][18][19][20][21][22][23][24][25][26] focusing on the domain of nanoelectronics.…”

Ionothermally synthesized hierarchical porous Schiff-base-type polymeric networks with ultrahigh specific surface area for supercapacitors

“…The Fourier transform infrared spectroscopy (FT-IR), 13 indicating that the nitrogen from melamine was high efficiently integrated into the polymeric networks. The gradual decline of total nitrogen content in HPPNs synthesized through the relatively longer polymerization processes can be ascribed to the further rearrangement or decomposition reactions of the aromatic frameworks in HPPN-400-ts.…”

Synthesis of mesoporous carbons using silica templates impregnated with mineral acids

“…From the XPS result, the content of P atoms in 1.3FA-OMC was determined to be 2.0 wt%. Such incorporation of heteroatoms into the carbon framework can alter the intrinsic chemical properties and therefore can result in catalytic function in various redox catalytic reactions [16,38,39].…”
