Tailoring the electronic arrangement of graphene by doping is a practical strategy for producing significantly improved materials oxygen-reduction reaction (ORR) in fuel cells (FCs). Recent studies have proven that carbon doped with elements, which larger (N) or smaller (P, B) electronegative atoms than such as N-doped nanotubes (CNTs), P-doped graphite layers and B-doped CNTs, also shown pronounced catalytic activity. Herein, we find graphenes similar electronegativity sulfur selenium, can...
Abstract Atomically thin boron nitride (BN) nanosheets are important two-dimensional nanomaterials with many unique properties distinct from those of graphene, but investigation into their mechanical remains incomplete. Here we report that high-quality single-crystalline mono- and few-layer BN one the strongest electrically insulating materials. More intriguingly, shows behaviours quite different graphene under indentation. In striking contrast to whose strength decreases by more than 30%...
An integrated, selective interlayer structure is developed to further mitigate the diffusion of polysulfides, simply by coating surface a C–S cathode with graphene/TiO2 film. It found that application film as an enables porous carbon nanotubes–S exhibit high reversible specific capacity and extraordinarily excellent cycling stability. As service our authors readers, this journal provides supporting information supplied authors. Such materials are peer reviewed may be re-organized for online...
Active sites and catalytic mechanism of nitrogen-doped graphene in oxygen reduction reaction (ORR) have been extensively studied but are still inconclusive, partly due to the lack an experimental method that can detect active sites. It is proposed this report on be determined via examination its chemical composition change before after ORR. Synchrotron-based X-ray photoelectron spectroscopy analyses three multilayer samples reveal intermediate OH(ads) which should chemically attach remains...
Semiconducting single-walled carbon nanotubes are studied in the diffusive transport regime. The peak mobility is found to scale with square of nanotube diameter and inversely temperature. maximum conductance, corrected for contacts, linear inverse These results good agreement theoretical predictions acoustic phonon scattering combination unusual band structure nanotubes. measurements set upper bound performance transistors operating
Millimeter-long and well-aligned single-walled carbon nanotubes (SWNTs) have been produced on silica/silicon surfaces using the monoxide chemical vapor deposition (CO-CVD) method. The orientation of nanotube arrays can be well-controlled by gas flow during growth. majority orientated SWNTs are straight individual. length >2 mm for a 10 min Furthermore, multidimensional crossed-networks SWNT easily generated multistep processes. These results present great opportunity in controllable...
The growth mechanism of long and aligned single walled carbon nanotubes using a recently reported "fast heating" chemical vapor deposition (CVD) method is discussed. effect heating speed at the initial stage CVD process has been systematically studied, "kite-mechanism" for nanotube proposed. understanding would enable us to design future experiments obtain better control morphology produced nanotubes.
N-Doped carbon dots synthesized by a one-pot solvothermal route displayed tunable luminescence due to different N contents. They could be directly applied in the imaging of peritoneal macrophages mice. This study provides new method tune carbon-based materials through non-metal doping.
Iodine-doped graphene has been successfully fabricated through a simple, economical, and scalable approach. The new metal-free catalyst can exhibit high catalytic activity, long-term stability, an excellent methanol tolerance for the oxygen reduction reaction.
Despite the good progress in developing doped carbon catalysts for oxygen-reduction reaction (ORR), current metal-free are still far from satisfactory large-scale applications of fuel cell. Developing new metal free materials with abundance active sites as well excellent electron transfer and reactant transport rate towards ORR may be a potential solution. Herein, we develop novel three-dimensional (3D) sulfur-nitrogen co-doped foams (S-N-CF) hierarchical pore structures, using convenient,...

The as-obtained products characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission microscopy, Brunauer−Emmett−Teller surface area, UV−vis diffuse-reflectance...
Water electrolysis is an emerging energy conversion technology, which significant for efficient hydrogen (H2) production. Based on the high-activity transition metal ions and alloys of ultrastable bifunctional catalyst, evolution reaction (HER) oxygen (OER) are key to achieving method by overall water splitting (OWS).

Lithium–sulfur (Li–S) batteries have a much higher energy density than Li ion and thus are considered as next generation for electric vehicle applications. However, the problem of rapid capacity fading due to shuttling soluble polysulfides between electrodes remains main obstacle practical Here, thin selective interlayer structure has been designed produced decrease charge transfer resistance mitigate problem, simply by coating surface cathode with film functionalized boron nitride...
The precursory carbon source is one of the key parameters which govern formation nanotubes (CNTs). In this work, by selecting four homologous series, namely n-pentane, n-hexane, n-heptane and n-octane, as investigated targets, we comparatively study relationship between thermodynamic properties aligned CNTs. We find that all these alkanes are favored for growth CNTs in a suitable environment. But only can yield with relatively high quality, narrow diameter distribution. Furthermore, after...

Recent studies have proven that carbon materials doped atoms which a relatively small atomic size (e.g. N, B, P or S), also shown pronounced catalytic activity. Herein, we demonstrate successful fabrication CNT/graphene Se atoms, large size, by simple, economical, and scalable approach....
Lithium–sulfur batteries have become an appealing candidate for next-generation energy-storage technologies because of their low cost and high energy density. However, one major practical problems is the solubility long-chain lithium polysulfides infamous shuttle effect, which causes Coulombic efficiency sulfur loss. Here, we introduced a concept involving dithiothreitol (DTT) assisted scission into lithium–sulfur system. Our designed porous carbon nanotube/S cathode coupling with...
