Zhang, Xuxu; Lin, Zitong; Ren, Xiaoyu; Qin, Chuanli; Meng, Qiuyu; Jiang, Xiankai published the artcile< High-performance supercapacitors enabled by boron/nitrogen co-doped carbons through WPU/PF/GO composite>, Quality Control of 112-63-0, the main research area is waterborne polyurethane phenolic resin graphene oxide supercapacitor electrochem performance.
In this study, a facile one-step carbonization was developed for producing B and N co-doped carbon through waterborne polyurethane, phenolic resin, and graphene oxide composite (nWPGC) used as electrode materials in supercapacitors. Furthermore, nitrogen-enriched carbon also had repetitive urethane bond (-NHCOO) in waterborne polyurethane (nWPU). Moreover, we used the ferric chloride treatment and washing method to remove the B-N bonds. The fabricated B/N co-doped carbon had a high specific capacitance of 356.3 F g-1 at 0.5 A g-1 in 6 M KOH electrolyte, with the surface area, and pore volume (611 m2 g-1 and 0.3 cm3 g-1). The assembled nWPGC-Fe-B//nWPGC-Fe-B sym. supercapacitor exhibited an energy d. of 10.35 Wh kg-1 was achieved at a power d. of 493.2 W kg-1. On top of that, the capacitor also maintained a well rate capability and brilliant cyclic stability of 89.78% capacitance retention even after 5000 cycles.
Ionics published new progress about Carbonization. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Quality Control of 112-63-0.
