Due to the increasing demand for military and commercial applications, magnetic metal-based core@shell nanostructures have attracted extensive attention in field of electromagnetic wave (EMW) absorption materials. To further improve overall performance, herein, an effective strategy is designed fabricate Co3Fe7@C yolk-shell structures by using (Co0.9Fe0.1)Fe2O4@phenolic resin as precursors. The structure parameters, including size CoFe alloy cores, thickness carbon shell, void between core...
Atomically dispersed metal catalysts often exhibit superior performance compared to that of nanoparticle in many catalysis processes. However, these so-called "single-atom" have a consistently low loading density on the support surface and easily aggregate at high temperatures, hindering their practical application. Herein, we demonstrate facile engineering protocol using molecule–surface charge transfer adducts fabricate highly stable noble with atomic dispersion, Pt/CeO2 catalyst as an...
Ce 3+ /Pr codoped Li 2 SrSiO 4 ( LSS ) phosphors with blue, red, and near‐infrared NIR tri‐emission have been prepared via a high‐temperature solid‐state reaction method. Under the excitation of 200 to 400 nm near‐ultraviolet n ‐ UV ), photoluminescence PL spectra are composed visible two parts. The former exhibits blue red emission bands centered at around 428 from 5 d –4 f transition 611 1 D → 3 H Pr , those overlap photosynthesis action plants absorption chlorophylls carotenoids. While...
We report a photochemical synthesis of Pd/CeO2 catalysts with atomically dispersed Pd. Compared to cubic CeO2 support (Pd/CeO2-CP), truncated octahedral (Pd/CeO2-TOP) exhibited higher activity and selectivity, owing the synergy between Pd atoms (111) surface CeO2. When compared clusters nanoparticles via chemical reduction, Pd/CeO2-TOP showed excellent an enhancement factor 324 in CO oxidation, as well by 344 selective oxidation benzyl alcohol.
Direct epoxidation of propylene by molecular oxygen alone is one the "dream reactions" in heterogeneous catalysis. Despite much effort, yield epoxide still too low to be commercially attractive due trade-off between conversion and selectivity. Here, we demonstrate that doping Cl into lattice Cu2O nanocrystals intergrowth method not only can enhance catalytic selectivity direct but also solve long-existing loss problem. In particular, Cl-doped rhombic dodecahedral with (110) exposing facets...
The supermoiré lattice, built by stacking two moiré patterns, provides a platform for creating flat mini-bands and studying electron correlations. An ultimate challenge in assembling graphene lattice is the deterministic control of its rotational alignment, which made highly aleatory due to random nature edge chirality crystal symmetry. Employing so-called "golden rule three", here we present an experimental strategy overcome this realize controlled alignment double-aligned hBN/graphene/hBN...
In this paper, we propose a multi-channel photonic crystal fiber sensor, which adopts dual-polarization and multiple materials to effectively reduce the mutual interference between channels enhance surface plasmon resonance, thus achieving simultaneous detection of with low interference. Four are polished around cylindrical fiber, then different metal films (gold or silver) plasmonic (titanium dioxide, thallium pentoxide, graphene) added sensing area each channel. All detect refractive...
Predictable synthesis of bimetallic nanocrystals with spatially controlled metal distributions offers a versatile route to the development highly efficient nanocatalysts. Here we report one-pot super branched Rh-on-Cu nanoscale sea urchins (Rh–Cu NSUrs) high density Cu–Rh interfaces by manipulating ligand coordination chemistry. Structural analysis and UV–vis spectra reveal that ascorbic acid can serve as Rh-selective in nonaqueous reverse reduction potentials Rh3+ Cu2+ cations. The...
