Synthesis of highly self-N-O-dual doped unique carbon blooming flower-like nanofiber derived novel snake-plant waste for ultrahigh energy of solid-state-supercapacitor

Abstract

This research expected to foster a novel bio-organic-derived highly Nitrogen (N)-Oxygen (O) self-dual-doped carbon (C) nanofiber (N/OCNF) using the green snake plant (Sansevieria trifasciata lauretii) for supercapacitor. The O-N doped carbon nanofibers were synthesized using a one-way system pyrolysis approach. The material conductivity was maintained through a binder-free dense circular design. The synthesized optimum CNF exhibited unique blooming flower-like nanofiber, connected nano-network, high mesopores ratio of 41 %, and enriched N (16.42 %) and O (4.35 %) heteroatoms. In the symmetrical cell shape, 850 N/OCNF-SP as optimum precursor exhibited an excellent capacitive feature of 347 F/g with retention capacity and coulombic efficiency were 76.94 % and 95.27 %, respectively. The symmetrical cell showed impressive energy output of 27.37 Wh kg−1 with low internal resistance of 0.72 Ω. This research proved a newly bio-organic-derived self-N/O double doped carbon nanofiber using one-way systems for excellent energy-power output of solid-state supercapacitor.
