Biomass derived phosphorous containing porous carbon material for hydrogen storage and high-performance supercapacitor applications

Modulating the porosity of carbons for improved adsorption of hydrogen, carbon dioxide, and methane: a review

“…6,308 Similar effects have also been reported by Ariharan et al for precursors containing phosphorous. [314][315] Self-activation may also have had a part to play in the unusual temperature-porosity relationship of a series of cigarette buttderived KOH-activated carbons. It is supposed that the unexpectedly high surface area (4300 m 2 g -1 ) of highly microporous sample activated at 600 o C may be a result of metal contaminants within the cigarette butt that assist KOH in the activation process.…”

A sustainable one-step strategy for highly graphitized capacitive carbons with hierarchical micro–meso–macro porosity

“…The GPC electrode can achieve 354.8, 323.9 and 188.7 F g À1 in H 2 SO 4 , KOH and Na 2 SO 4 aqueous electrolytes at 1 A g À1 , respectively, which are comparable and even higher than those of many previously reported biomass-derived porous carbon electrodes. [43][44][45][46] Based on the capacitive performance of GC, PC and GPC in different electrolytes, the PC electrode exhibits a higher capacitance value than that of the GC electrode, demonstrating that a superior porosity, especially a high microporosity, plays a crucial role in the capacitive performance of the material. Compared to the PC electrode, the GPC electrode shows better capacitive properties in spite of its decreased microporosity, which suggests that a highly graphitized carbon skeleton and a hierarchical porosity can promote the capacitive performance of the electrode.…”

Synthesis Methods and Applications of Semiconductor Material ZnWO4 with Multifunctions and Multiconstructions

“…Therefore, they have been widely studied worldwide. [ 99–103 ] Among all factors, electrode materials play the most important role in the performance of supercapacitors. Due to the lack of electrodes with excellent electrochemical performance, the practical application of supercapacitors is limited.…”
