Identification of catalytic sites for oxygen reduction reaction (ORR) and evolution (OER) in carbon materials remains a great challenge. Here, we construct pyridinic-N-dominated doped graphene with abundant vacancy defects. The optimized sample an ultrahigh pore volume (3.43 cm3 g–1) exhibits unprecedented ORR activity half-wave potential 0.85 V alkaline. For the first time, density functional theory results indicate that quadri-pyridinic N-doped site synergized defect is active site, which...
3d transition metals or their derivatives encapsulated in nitrogen-doped nanocarbon show promising potential non-precious metal oxygen electrocatalysts.
Abstract Sodium‐ion hybrid capacitors (SIHCs) can potentially combine the virtues of high‐energy density batteries and high‐power output as well long cycle life in one device. The key point constructing a high‐performance SIHC is to couple appropriate anode cathode materials, which match capacity kinetics behavior simultaneously. In this work, novel SIHC, coupling titanium dioxide/carbon nanocomposite (TiO 2 /C) with 3D nanoporous carbon cathode, are both prepared from metal–organic...
Metal-free bifunctional oxygen electrocatalysts are extremely critical to the advanced energy conversion devices, such as high metal-air batteries. Effective tuning of edge defects and electronic density on carbon materials via simple methods is especially attractive. In this work, a facile alkali activation method has been proposed prepare with large specific surface area optimized porosity. addition, subsequent nitrogen-doping leads pyridinic-N graphitic-N contents abundant defects,...
Porous silicon carbide (SiC) has attracted considerable attention as an alternative catalyst support, particularly in corrosive and high-temperature environment. Herein, we report a facile strategy to controllably fabricate macroporous, meso-microporous macro-meso-microporous SiC ultrathin fibers (M-SFs, MM-SFs MMM-SFs, respectively) mats with good flexibility via electrospinning combined polymer-derived ceramics route. The formation mechanism of different porous structures been discussed....
Designing a novel heterojunction structure on SiC gas sensing material is extremely desirable for high-performance sensors applied in harsh environments. Inspired by the unprecedented catalyzing effect of single-atom catalysts, here, we have sequentially loaded tin oxide nanorods (SnO2 NRs) and platinum single atoms (Pt SAs) silicon carbide nanosheets (SiC NSs) to build Pt SAs@SnO2 NRs@SiC NSs multi-heterojunction. Gas based show highly enhanced performance, including high response (119.75 ±...
The SnO<sub>2</sub> NS@SiC NF sensor shows an ultrafast response/recovery rate, high sensitivity, excellent reproducibility, good sensing selectivity and outstanding long-term stability toward ethanol, even at temperature.
Fast and effective detecting of flammable explosive gases in harsh environments (high temperature, corrosion atmosphere) is crucial for preventing severe accidents the chemical industry, fuel cell applications engine tests. Silicon carbide material reported to be a good candidate gas sensing devices applied extreme conditions. Herein, high-temperature available silicon nanosheets (SiC NSs) were synthesized from graphene oxide (GO) via catalyst-free carbothermal method. The structure...
The nanocomposite BaFe 12 O 19 ( BFO )/ Ni 0.5 Zn Fe 2 4 NZFO )‐aligned microfibers with diameters 0.8–2 μm and high aspect ratios have been prepared by the gel precursor transformation process, where is hard magnetic phase soft phase. binary ferrites are formed after calcined at 1000°C for 3 h. These aligned exhibit a clear shape anisotropy. Their difference observed 297 77 K largely arises from competition of exchange‐coupling interaction thermal fluctuation on dipolar interaction....
