Sheet-like graphitic carbon with a porous structure can provide low-resistant pathways and short ion-diffusion channels for energy storage, thus is expected to be an excellent material high-power supercapacitors. Herein, graphene-like nanosheets (PGNSs) large surface area were synthesized the first time via easy cost-effective SAG (simultaneous activation–graphitization) route from renewable biomass waste coconut shell. In synthesis, catalyst precursor (FeCl3) activating agent (ZnCl2)...

Abstract Separated boron and nitrogen porous graphitic carbon (BNGC) is fabricated by a facile hydrothermal coordination/ZnCl 2 ‐activation process from renewable inexpensive nitrogen‐containing chitosan. In this synthetic pathway, chitosan, which has high content, first coordinates with Fe 3+ ions to form chitosan–Fe that subsequently reacts boric acid (boron source) generate the BNGC precursor. After simultaneous carbonization ZnCl activation followed removal of catalyst, BNGC, containing...

Organic afterglow materials based on carbon dots (CDs) have aroused extensive attention for their potential applications in sensing, photoelectric devices, and anticounterfeiting. Effective methods to control the CD structure modulate energy levels are critical but still challenging. Here, we demonstrate a method emission of CDs@SiO2 composites by controlling carbonization degree CDs with variable calcining temperatures. The CDs@SiO2-Raw prepared hydrothermal bottom-up synthesis shows more...

The deformation-coordination ability between ductile metal and brittle dispersive ceramic particles is poor, which means that an improvement in strength will inevitably sacrifice ductility dispersion-strengthened metallic materials. Here, we present inspired strategy for developing dual-structure-based titanium matrix composites (TMCs) achieve 12.0% elongation comparable to the Ti6Al4V alloys enhanced compared homostructure composites. proposed dual-structure comprises a primary structure,...

Abstract B,N-codoped carbon nanostructures (BNCS) can serve as alternative low-cost metal-free electrocatalysts for oxygen reduction reactions (ORR). However, the compensation effect between p- (B atoms) and n-type (N dopants would make covalent boron-nitride (BN) easily formed during synthesis of BNCS, leading to a unsatisfactory ORR activity. Therefore, it has been challenging develop facile rapid synthetic strategies highly active BNCS without forming direct BN. Here, method is developed...
