A preheated high-temperature environment is believed to be critical for a chemical-exfoliation-based production of graphenes starting from graphite oxide, belief that based on not only experimental but also theoretical viewpoints. novel exfoliation approach reported in this study, and the process realized at very low temperature, which far below proposed by introducing high vacuum process. Owing unique surface chemistry, low-temperature exfoliated demonstrate an excellent energy storage...
Homogeneous single-layer graphene films are fabricated using an electrophoretic deposition technique, and their field-emission properties investigated. The show high density, uniform thickness, numerous edges normal to the film surface, good interface contact adhesion with substrate, consequently excellent properties.
Single-atom catalysts (SACs) are the smallest entities for catalytic reactions with projected high atomic efficiency, superior activity, and selectivity; however, practical applications of SACs suffer from a very low metal loading 1-2 wt%. Here, class based on atomically dispersed transition metals nitrogen-doped carbon nanotubes (MSA-N-CNTs, where M = Ni, Co, NiCo, CoFe, NiPt) is synthesized an extraordinarily loading, e.g., 20 wt% in case NiSA-N-CNTs, using new multistep pyrolysis process....

Lithium-sulfur (Li-S) batteries are promising next-generation energy storage technologies due to their high theoretical density, environmental friendliness, and low cost. However, conductivity of sulfur species, dissolution polysulfides, poor conversion from reduction, lithium sulfide (Li2S) oxidation reactions during discharge-charge processes hinder practical applications. Herein, under the guidance density functional theory calculations, we have successfully synthesized large-scale single...
Copper electrocatalysts derived from an oxide have shown extraordinary electrochemical properties for the carbon dioxide reduction reaction (CO2RR). Using in situ ambient pressure X-ray photoelectron spectroscopy and quasi electron energy-loss a transmission microscope, we show that there is substantial amount of residual oxygen nanostructured, oxide-derived copper but no oxide. On basis these findings combination with density functional theory simulations, propose subsurface changes...

Single-wall carbon nanotubes (SWCNTs) are ideal for fabricating transparent conductive films because of their small diameter, good optical and electrical properties, excellent flexibility. However, a high intertube Schottky junction resistance, together with the existence aggregated bundles SWCNTs, leads to degraded optoelectronic performance films. We report network isolated SWCNTs prepared by an injection floating catalyst chemical vapor deposition method, in which crossed welded graphitic...
Designing high-performance and low-cost electrocatalysts is crucial for the electrochemical production of hydrogen. Dislocation-strained IrNi nanoparticles loaded on a carbon nanotube sponge (DSIrNi@CNTS) driven by unsteady thermal shock in an extreme environment are reported here as highly efficient hydrogen evolution reaction (HER) catalyst. Experimental results demonstrate that numerous dislocations kinetically trapped self-assembled due to ultrafast quenching different atomic radii,...
The development of efficient Fe–N–C materials enriched with single-atom Fe sites toward the oxygen reduction reaction (ORR) is still a great challenge because atoms are mobile and easily aggregate into nanoparticles during high-temperature treatment.
