A spatial confinement effect of copper nanoparticles in an ordered mesoporous γ-Al2O3, which is synthesized by evaporation induced self-assembly (EISA) method, was investigated to verify the enhanced catalytic activity and stability with less aggregation crystallites during direct synthesis dimethyl ether (DME) from syngas. The surface acidity Al2O3 metallic area significantly altered stability. mesopore structures were effective suppress even under reductive CO hydrogenation conditions...
Over the history of carbon, it is generally acknowledged that Bernal AB stacking sp2 carbon layers unique crystalline form graphite. The universal graphite structure synthesized at 2,600~3,000 °C and exhibits a micro-polycrystalline feature. In this paper, we provide evidence for metastable with an AA' structure. non-Bernal allotrope by thermal- plasma-treatment graphene nanopowders ~1,500 °C. formation bilayer nuclei facilitates preferred texture growth results in single-crystal nanoribbons...
Raman spectra of single-wall carbon nanotubes (SWNTs) exhibit a unique radial breathing mode (RBM) band (∼100–300 cm–1) and G– peak (∼1570 cm–1), along with D (∼1350 cm–1). We show that the typical signals for SWNTs are signature their helical structure determined using density functional theory simulation structural analysis hydrogenated dehydrogenated SWNT samples. demonstrate at ∼1570 cm–1 is to opened tubular graphene structures ∼2 nm diameter. also ∼1350 originated from edge defects...
The combined steam and CO2 reforming reaction of CH4 was investigated using LaSrNiOx mixed oxides supported on Al2O3-modified β-SiC to elucidate the largely enhanced conversion at an optimal concentration Al2O3 modifier. dispersion SiC support simultaneously altered crystallites increasing their strength when with SiC. Although all tested catalysts showed similar activation energies, increased around 10 wt % modifier well-correlated active perovskite-like La2NiO4 which resulted in catalytic...
