Abstract Recently great efforts have been focused on converting biowastes into high-valued carbon materials. However, it is still a challenge to achieve high yield and controllable porous distribution in both industrial academic research. Inspired by the multi-void structure of waste coffee grounds, herein we fabricated hierarchical via combination catalytic carbonization alkali activation. The process was applied obtain well-defined mesoporous with as 42.5 wt%, subsequent activation...
ABSTRACT Converting waste plastics into valuable carbon materials has obtained increasing attention. In addition, have shown to be the ideal electrode for double‐layer supercapacitors owing their large specific surface area, high electrical conductivity, and stable physicochemical properties. Herein, an easily operated approach is established efficiently convert poly(ethylene terephthalate) beverage bottles porous nanosheet (PCNS) through combined processes of catalytic carbonization KOH...
Abstract Carbon-based supercapacitors have aroused ever-increasing attention in the energy storage field due to high conductivity, chemical stability, and large surface area of investigated carbon active materials. Herein, eucalyptus-derived nitrogen/oxygen doped hierarchical porous carbons (NHPCs) are prepared by synergistic action ZnCl 2 activation NH 4 Cl blowing. They feature superiorities such as specific area, rational porosity, sufficient N/O doping. These excellent physicochemical...
Recently porous carbon hybrids have attracted ever-increasing attention as electrode materials for supercapacitors, but it remains a great challenge to simultaneously control their pore structure and element composition with optimal electrochemical performances. Herein, Na3PO4 assistant dispersion of nano-CaCO3 template in egg white was proposed fabricate nitrogen/oxygen/phosphorus (N/O/P) co-doped 3D hierarchical hybrids. The as-prepared exhibited high surface area (2576 m2 g−1),...
Porous carbon-based supercapacitor has been regarded as a promising candidate for powering wearable electronics. To improve its energy density and mechanical flexibility, great efforts have made to design ideal porous carbon. However, it is still difficult synthesize carbon with reasonable pore size distribution. Herein, glucose-derived two-dimensional nitrogen-doped hierarchical nanosheets (2D-NPC) are synthesized through one-step pyrolysis-activation process. Melamine potassium oxalate...
Summary Poly(butylene succinate)/magnesium hydroxide (PBS/Mg(OH) 2 ) composites were prepared by melt compounding to investigate the effect of particle size on flame retardancy PBS. Their flammability properties investigated limiting oxygen index, UL‐94, and cone calorimeter tests, which suggested that medium‐sized Mg(OH) ‐5 µm displayed best retardancy. The residual char structure analyzed indicated could form a better protective layer than other sized particles, leading Copyright © 2016...
Carbon-based supercapacitors have attracted considerable academic and practical interest due to their advantages of low cost, high power density, superior durability. Herein, we report the facile synthesis hierarchical porous carbon sheets (HPCSs) featuring a specific surface area (2788 m2 g-1), derived from pyrrole through combination MgO template carbonization KOH activation. The pores with co-existence micropores mesopores were obtained in HPCSs. Benefiting area, well-balanced pore size...
A facile and sustainable approach was established to convert polystyrene into porous carbon sheets hollow shells over magnesium oxide templates with different morphologies.
Abstract The high specific surface area and the fine electrical conductivity are vital impacts, but they always a pair of mutually counterbalancing factors in carbon‐based supercapacitors. Herein, facile strategy combined CoCl 2 catalytic graphitization ZnCl activation is applied to synthesize porous carbonaceous materials with enriched nitrogen oxygen doping from cheap abundant biowaste peanut shells. as‐produced carbon possess (1745–2257 m g −1 ), naturally nitrogen/oxygen co‐doping,...
