Au nanoparticles (NPs) uniformly embedded into an ultrathin hollow graphene nanoshell (Au@HGN) are synthesized using a facile template-based procedure. The obtained Au@HGN catalyst exhibits robust and stable catalytic performance in the reduction of 4-nitrophenol to 4-aminophenol, compared with that traditional Au/TiO2 previously reported Au- Ag-based catalysts.
Abstract Transition metal dichalcogenides (TMDs) exhibit excellent electronic and photoelectric properties under pressure, prompting researchers to investigate their structural phase transitions, electrical transport, response upon compression. Herein, the of layered ZrS 2 pressure using in situ high‐pressure photocurrent, Raman scattering spectroscopy, alternating current impedance absorption theoretical calculations are studied. The experimental results show that photocurrent continuously...
Compared with other carbon materials, the surface chemistry, electronic properties and corresponding catalytic performance of nanodiamond its derivatives are investigated.
Dehydrogenation of ethylbenzene to styrene is one the most important catalytic processes in chemical industry. While it was demonstrated that nanocarbons like nanotubes, nanodiamond, or nanographite show high performance, especially selectivity, these powders give rise handling problems, pressure drop, hampered heat and mass transfer, unclear health risks. More common macroscopic carbon materials activated carbons unsatisfying selectivity below 80%. In this study, mesoporous, graphitic, easy...
Reduced porous graphene oxide as a metal free catalyst was selected for the oxidative dehydrogenation of ethylbenzene to styrene and it exhibited high activity stability.
Photocatalytic water splitting, using solar energy to obtain hydrogen, is an ideal technology for producing new energy. In the process of photocatalysis, improvement catalytic performance catalysts used a matter great concern scientists. So far, there are many problems preventing improvements in photocatalytic performance. this paper, we propose atom-doping method, which effective method improve We present type graphene-like carbon nitride material, whose primitive cell composed 12 atoms and...
Abstract For the first time, significant improvement of catalytic performance nanodiamonds was achieved for dehydrogenation ethylbenzene to styrene under oxygen‐lean conditions. We demonstrated that combination direct and oxidative indeed occurred on nanodiamond surface throughout reaction system.

Selective oxidation of substituted phenols to p-benzoquinones is known be inefficient because the competing C–O coupling reaction caused by phenoxy radicals. The poor stability conventional metal-based catalysts represents another bottleneck for industrial application. Here, we describe a metal-free pathway in which onion-like carbon (OLC) as low-cost catalyst exhibits excellent catalytic activity and selective mono-, di- trisubstituted their corresponding p-benzoquinones, even better than...
The electronic structure of the graphitic carbon nitride (g-C<sub>6</sub>N<sub>6</sub>) under strain was obtained using hybrid density functional HSE06 with a larger computational workload.
The electronic structure of g-C3N4/C2N-h2D nanoribbons was investigated by first-principles calculations. As a splice structure, we first computed the three magnetic coupled states nanoribbons. After self-consistent calculations, both antiferromagnetic and paramagnetic coupling become ferromagnetic states. It proved that state is most stable state. Thermodynamic stability subsequently verified based on had steady electron spin polarization, with moment 1 μB for each primitive cell. changed...
