Porous Fe2O3 nanocubes composed of fine Fe2O3 nanoparticles have been facilely synthesized by simultaneous oxidative decomposition of Prussian blue (PB) nanocubes at high temperature. When evaluated as an anode material for lithium-ion batteries, the as-obtained porous Fe2O3 nanocubes manifest high specific capacity (…
The selective oxidation of glycerol was investigated using AuPd/TiO2 as the catalyst in the presence of AlCl3, and lactic acid was obtained as the predominant product. It was demonstrated that AuPd/TiO2 and AlCl3 played synergistic roles in the production of lactic acid. The possible reaction pathway was proposed, in…
In this contribution we present recent experi- mental and theoretical results on local near-field assisted laser ablation. Along these lines, we have generated sub- diffraction sized nanostructures on fused silica substrates, exploiting the local near fields of highly ordered triangu- lar gold nanoparticle arrays gene…
A nanocluster composite assembled by interconnected ultrafine SnO2-C core-shell (SnO2@C) nanospheres is successfully synthesized via a simple one-pot hydrothermal method and subsequent carbonization. As an anode material for lithium-ion batteries, the thus-obtained nano-construction can provide a three-dimensional tra…
Herein we report the synthesis and characterization of light responsive metal organic framework (MOF) single crystals containing the photochromic diarylethene 1,2-bis(2,5-dimethyl-thien-3-yl)perfluorocyclopentene. Polarized light microscopy on single crystals indicates that the photochrome is preferentially aligned al…
Ag0.1Pd0.9 nanoparticles assembled on reduced graphene oxide are synthesized by a facile co-reduction route. The resultant AgPd nanoparticles/reduced graphene oxide exert 100% H2 selectivity and exceedingly high activity toward the complete decomposition of formic acid at room temperature under ambient conditions.
The crystal structure of the 18650-type Li-ion cell constituents has been studied at ambient temperature by high-resolution neutron powder diffraction at different states of charge. The structure evolution occurring on the anode (graphite) site as a function of the cell state has been accurately monitored by simultane…
Palladium nanoparticles supported on a mesoporous graphitic carbon nitride, Pd@mpg-C3N4, has been developed as an effective, heterogeneous catalyst for the liquid-phase semihydrogenation of phenylacetylene under mild conditions (303 K, atmospheric H2). A total conversion was achieved with high selectivity of styrene (…
Ag 3 PO 4 as a photocatalyst has attracted enormous attention in recent years due to its great potential in harvesting solar energy for environmental purification and fuel production. The photocatalytic performance of Ag 3 PO 4 strongly depends on its morphology, exposed facets, and particle size. The effects of morph…
The deactivation of 0.5 wt% Pt/Al2O3 and 0.5 wt% Pt-1.5 wt% Sn/Al2O3 catalysts has been studied by operando Raman spectroscopy during the dehydrogenation of propane and subsequent regeneration in air for 10 successive dehydrogenation-regeneration cycles. Furthermore, the reaction feed was altered by using different pr…
To prepare a water-soluble catalyst for photocatalytic hydrogen (H2) evolution, a simple hydrophobic precursor of [FeFe]–H2ase mimics, Fe2S2(CO)6, has been successfully assembled on the surface of CdSe QDs using an interface-directed approach in aqueous/organic solution. The resulting photocatalyst shows the highest e…
Mesoscopic solar cells are one of the most promising photovoltaic technologies among third generation photovoltaics due to their low cost and high efficiency. The morphology of wide-band semiconductors, sensitized with molecular or nanosized light harvesters, used as electron collectors contribute substantially to the…
Stimulated by the growing importance and recognized toxicity of anions such as fluoride, cyanide and azides, we have, in the past few years, developed a family of Lewis acidic triarylboranes that can be used for the complexation of these anions in organic and protic solvents, including water. A central aspect of our a…
Graphene nanosheets (GNSs) have been considered as potential conductive additives for electrodes in Li-ion batteries to replace the existing carbon black (CB). Graphene has exceptionally high aspect ratio and excellent electrical conductivity, enabling the formation of extensive conductive networks at a much lower con…
Photodynamic therapy is widely used in clinics and for anti-bacterial applications. The major challenge is the limited depth of tissue penetration of light and poor targetability. In this study, magnetite nanoparticles were used as a highly sensitive T2-weighted MR imaging contrast agents to target the tumor and mimic…
Development of nano-sized carriers including nanoparticles, nanoemulsions or liposomes holds great potential for advanced delivery systems for cancer immunotherapy, as such nanostructures can be used to more effectively manipulate or deliver immunologically active components to specific target sites. Successful develo…
In this study, silicon–graphite composites were prepared and investigated as anode materials for Li-ion batteries with small amounts of silicon and different binders. The silicon powders were prepared by ball-milling crystalline silicon for 100 h and 200 h. After 200 h, an average silicon particle size of 0.73 μm was…
Rational assembly from a layer structure to a pillared-layer metal-organic framework affords an ideal microporous material with large Langmuir surface area for highly selective separation of hydrocarbons.
Using graphene oxide (GO) as both a reducing agent and a support, a two-step method was used to fabricate GO decorated with Au–Ag alloy nanoparticles with an Au-rich shell. The material exhibited excellent catalytic activity for the reduction of 4-nitrophenol to 4-aminophenol in water at room temperature and its activ…
Free-standing and binder-free Co3O4/graphene films were fabricated through vacuum filtration and thermal treatment processes, in which sheet-like Co3O4 and graphene were assembled into a robust lamellar hierarchical structure via electrostatic interactions. The morphological compatibility coupled with strong interfaci…
